Can you ask the built-in assistant a question in plain English?

Yes
Quoted from BigQuery’s docsConversational analytics in BigQuery lets you chat with agents about your data using natural language.
Source: docs.cloud.google.com/bigquery/docs/conversational-analytics · checked Oct 26, 2026 · quoted by Claude
Claude yes · GPT yes · Gemini yes
Grading standard

Someone types a question the way they would say it out loud and the built-in assistant returns an answer or a working query against your data, without needing SQL or a dashboard someone built first. An assistant that only suggests or completes SQL the user is already writing is partly; one that writes the query from a plain-English description is yes, including inside a code editor.

Can you refine the answer by carrying on the conversation?

Yes
Quoted from BigQuery’s docsContinues a stateful conversation by sending a chat message that references an existing conversation and its associated agent context.
Source: docs.cloud.google.com/gemini/data-agents/conversational-analytics-api/overview · checked Oct 26, 2026 · quoted by Claude
Claude yes · GPT yes · Gemini yes
Grading standard

The assistant holds the thread, so you can say “now split that by region” and it knows what you are referring to.

Does the answer expose the query or analytical steps used to derive it?

Yes
Quoted from BigQuery’s docsThe Summary section includes the generated query followed by the query result.
Source: docs.cloud.google.com/bigquery/docs/create-conversations · checked Oct 26, 2026 · quoted by Claude
Claude yes · GPT yes · Gemini yes
Grading standard

The answer exposes the query or analytical steps used to derive it. Named fields belong to field citation; upstream dependencies belong to lineage.

Does the answer say which specific tables, columns or metrics it was built from?

Partly
Quoted from BigQuery’s docsMetadata about the conversation, such as the agent and data sources used.
Source: docs.cloud.google.com/bigquery/docs/create-conversations · checked Oct 26, 2026 · quoted by Claude
Claude partly · GPT yes · Gemini partly
Grading standard

Named tables, columns or metrics attached to the answer, such as a field list or a citation shown with it. The text of a generated query is credited to the analytical-steps row, not this one, even though it names tables. Naming only the dataset does not count.

Can the AI analyze a CSV or spreadsheet a user uploads?

Yes
Quoted from BigQuery’s docsTo analyze a CSV using the DSA in BigQuery, follow these steps.
Source: docs.cloud.google.com/bigquery/docs/colab-data-science-agent · checked Oct 26, 2026 · quoted by Claude
Claude yes · GPT yes · Gemini yes
Grading standard

A user can give the product a CSV or spreadsheet and use the AI to analyze its contents.

Can the AI clean or reshape data while leaving inspectable transformation logic?

Yes
Quoted from BigQuery’s docsThis document explains how to clean and transform your data within BigQuery data preparations using SQL code suggestions from Gemini.
Source: docs.cloud.google.com/bigquery/docs/data-prep-get-suggestions · checked Oct 26, 2026 · quoted by GPT
Claude yes · GPT yes · Gemini yes (preview)
Grading standard

The AI can clean or reshape data and leaves transformation steps, code or another inspectable artifact behind.

Can the AI combine two or more data sources in one analysis?

Yes
Quoted from BigQuery’s docsThis feature lets you query and join regional open-source format tables (stored in Cloud Storage) directly alongside your BigQuery tables.
Claude partly · GPT yes · Gemini yes (preview)
Grading standard

The AI joins or blends at least two sources, for example two databases or a database and an uploaded file. Tables in one database are one source, and analyzing an uploaded file on its own is the file-upload row.

Can the AI select and create a visualization suited to the analytical question?

Yes
Quoted from BigQuery’s docsWhen you ask a question that doesn't specify a results format, the Conversational Analytics API determines the format that's best suited to the specific criteria and the key terms that are provided in the question.
Claude yes · GPT yes · Gemini yes
Grading standard

The AI selects and creates a chart or table suited to the question, rather than only changing a visualization the user chose.

Can the AI identify what contributed to a change, with calculations a person can check?

Yes
Quoted from BigQuery’s docsConversational analytics supports the following AI and ML functions in response to chats with data agents and data sources, and in verified SQL queries that you create.
Source: docs.cloud.google.com/bigquery/docs/conversational-analytics · checked Oct 26, 2026 · quoted by Claude
Claude yes · GPT yes · Gemini yes
Grading standard

yes: the built-in assistant breaks a change down into contributing segments or factors and shows the contribution of each, with the calculation a person can check, for example a table of segments with their share of the change. A key-driver function the assistant is documented to use counts; one only a user calls in SQL does not. Naming likely causes, or describing that a number rose or fell, without contributions is partly.

Can the AI produce a forecast and expose the assumptions behind it?

Partly
Quoted from BigQuery’s docs- "Using SQL, forecast the future traffic of my website for the next month based on bigquery-public-data.google_analytics_sample.ga_sessions_. Then, plot the historical and forecasted values."
Source: docs.cloud.google.com/bigquery/docs/colab-data-science-agent · checked Oct 26, 2026 · quoted by GPT
Claude partly · GPT partly · Gemini partly
Grading standard

The AI creates a forecast and exposes its horizon, inputs and assumptions so the result can be challenged. A forecast that does not expose its assumptions is partly. The AI itself must produce the forecast, so a classic forecasting feature it does not drive does not count, and a horizon with a confidence range but no stated inputs is partly.

Can the AI calculate and compare what-if scenarios, each with its changed assumptions stated?

Not found
Nothing in the docs settles this.
Claude nothing found · GPT nothing found · Gemini nothing found
Grading standard

A user can define more than one what-if scenario with the AI, the changed assumptions of each scenario are stated explicitly, and the AI calculates results for each that can be compared side by side. A single what-if answer, or scenarios without stated assumptions or calculated results, is partly.

Does the answer expose data freshness or staleness to the user?

Not found
Nothing in the docs settles this.
Claude nothing found · GPT nothing found · Gemini nothing found
Grading standard

The answer exposes the age or last-refresh time of the data it used, so stale output is visible at the point of use. Freshness shown with the answer through the data source's own indicator, for example a "last refreshed" badge on the dataset the answer used, is partly.

Chart logic 4

Can the built-in assistant read the calculation behind a chart or table in BI content?

Partly
Quoted from BigQuery’s docsYou can prompt Gemini in BigQuery to explain a SQL query in natural language.
Source: docs.cloud.google.com/bigquery/docs/write-sql-gemini · checked Oct 26, 2026 · quoted by Claude
Claude partly · GPT partly · Gemini partly
Grading standard

The assistant can read the calculation behind a chart or table in BI content: its formula, measure or the query that feeds it. Reading SQL in an editor, worksheet or notebook cell that no chart in BI content uses is partly.

Can the built-in assistant write the calculation behind a chart or table in BI content?

Partly
Quoted from BigQuery’s docsYou can generate SQL in the query editor by describing the query that you want in a comment.
Source: docs.cloud.google.com/bigquery/docs/write-sql-gemini · checked Oct 26, 2026 · quoted by Claude
Claude partly · GPT yes (preview) · Gemini partly
Grading standard

The assistant writes or changes the calculation behind a chart or table in BI content. Writing SQL in an editor, worksheet or notebook cell is partly.

Can an outside coding agent read the calculation behind a specific chart or table in BI content?

Not found
Nothing in the docs settles this.
Claude nothing found · GPT nothing found · Gemini nothing found
Grading standard

An outside agent can retrieve, through the vendor's API, CLI, MCP server or skills, the calculation behind a specific chart or table in BI content. Downloading a whole file or workbook it must then parse is partly.

Can an outside coding agent write the calculation behind a specific chart or table in BI content?

Not found
Nothing in the docs settles this.
Claude nothing found · GPT nothing found · Gemini nothing found
Grading standard

An outside agent can change the calculation behind a specific chart or table in BI content through the vendor's interface. Styling need not be writable. Replacing a whole file or workbook is partly.

Saved content, sharing & reuse 6

Can the built-in assistant open and work from existing BI content?

Partlypreview
Quoted from BigQuery’s docsThe assistant works with new or existing data canvases.
Source: docs.cloud.google.com/bigquery/docs/data-canvas · checked Oct 26, 2026 · quoted by Claude
Claude partly (preview) · GPT partly · Gemini partly (preview)
Grading standard

The assistant can open existing BI content and work from what it shows. Analyst work only (a notebook, SQL worksheet or SQL file that people edit rather than view) is partly.

Can the built-in assistant build persistent, governed BI content?

Partly
Quoted from BigQuery’s docsAs the plan runs, generated code and text appear in the notebook.
Source: docs.cloud.google.com/bigquery/docs/colab-data-science-agent · checked Oct 26, 2026 · quoted by Claude
Claude partly · GPT yes (preview) · Gemini partly
Grading standard

The assistant builds persistent BI content with an owner, permissions and a live governed data source. Analyst work only (a notebook, a SQL file) is partly.

Can an outside coding agent read the contents of existing BI content?

Partly
Quoted from BigQuery’s docsTo manage BigQuery Studio saved queries by using the BigQuery API:

Claude partly · GPT partly · Gemini partly
Grading standard

An outside agent can create BI content through the vendor's interface, the way it would open a pull request. Analyst work only is partly.

Can a user share AI-created BI content with named users or groups, with each viewer seeing only what their own permissions allow?

Partlypreview
Quoted from BigQuery’s docsAll viewers see the rendered Data Apps based on the author's access.
Source: docs.cloud.google.com/bigquery/docs/colab-data-apps · checked Oct 26, 2026 · quoted by Claude
Claude partly (preview) · GPT partly (preview) · Gemini partly (preview)
Grading standard

yes: AI-created BI content can be shared with named users or groups and each viewer sees only the data their own permissions allow (results evaluated as the viewer). Sharing that shows the author's results to everyone is partly. An asset counts as AI-created only if the AI built it, not if a person pasted AI-generated SQL into it.

Can permitted users find colleagues' saved analytical assets through workspace-wide browse or search?

Yes
Quoted from BigQuery’s docsUsers with the dataform.repositories.list permission—which is included in standard BigQuery roles such as BigQuery Job User, BigQuery Studio User, and BigQuery User—can see all code assets in the Explorer panel of the Google Cloud project, regardless of whether they created these assets or these assets were shared with them.
Source: docs.cloud.google.com/bigquery/docs/data-canvas · checked Oct 26, 2026 · quoted by Claude
Claude yes · GPT yes · Gemini yes
Grading standard

Permitted users can browse or search across the workspace for saved analytical assets created by colleagues, including AI-created work.

Built-in agents 7

Can you save a built-in assistant with its own instructions, data and permissions, and let colleagues reuse it?

Yes
Quoted from BigQuery’s docsData agents consist of one or more knowledge sources, and a set of instructions specific to a use case for processing that data.
Source: docs.cloud.google.com/bigquery/docs/conversational-analytics · checked Oct 26, 2026 · quoted by GPT
Claude yes · GPT yes · Gemini yes
Grading standard

An assistant someone configures once, with its own instructions, data and permissions, that colleagues can then reuse.

Can the product’s AI or an agent rerun a defined analysis on a schedule or trigger and deliver a fresh result or alert?

Partlypreview
Quoted from BigQuery’s docsSchedule a query by providing the following details in your prompt:
Source: docs.cloud.google.com/bigquery/docs/use-cloud-assist · checked Oct 26, 2026 · quoted by Claude
Claude partly (preview) · GPT partly (preview) · Gemini partly (preview)
Grading standard

The product’s AI or an agent can rerun a defined analytical task on a schedule or trigger and deliver a fresh result or alert without a person present. An ordinary report or dashboard schedule that the AI or an agent does not run does not count, and an AI that only sets up such a schedule is partly.

Can an agent do something beyond answering, write back, notify, call another system?

Partly
Quoted from BigQuery’s docsThe Data Engineering Agent cannot execute pipelines. You must review and run or schedule pipelines.
Source: docs.cloud.google.com/bigquery/docs/data-engineering-agent-pipelines · checked Oct 26, 2026 · quoted by Claude
Claude partly · GPT partly · Gemini partly
Grading standard

yes: a built-in agent can, on its own, cause a named side effect outside the analytics content: send a message or notification, call a webhook or another system, or write data to a destination. Writing to the product's own dashboards or notebooks does not count. Generating code a person must then run is partly.

Does the documentation describe how an agent hands a task back to a person when it cannot proceed?

Partly
Quoted from BigQuery’s docsThe agent might also generate an agent plan automatically and request your approval.
Source: docs.cloud.google.com/gemini/data-agents/data-engineering-agent/agent-overview · checked Oct 26, 2026 · quoted by Claude
Claude partly · GPT yes · Gemini partly
Grading standard

yes: a built-in agent that cannot finish a task stops and hands it to a person, with the hand-off documented (a notification, a review queue, a pause awaiting a decision). Asking the user a clarifying question during a conversation is partly. Silence is nothing found.

Can a customer configure one agent to delegate a bounded analytical task to another named agent?

Partly
Quoted from BigQuery’s docsSeamless orchestration: Ask a general analytical question (for example, "How is our sales pipeline trending in the last 3 months?") and Gemini Enterprise automatically routes the query to the relevant data agent.
Source: docs.cloud.google.com/bigquery/docs/create-data-agents · checked Oct 26, 2026 · quoted by Claude
Claude partly · GPT partly · Gemini partly
Grading standard

A customer can configure one agent to delegate a bounded analytical task to another named agent with explicit tools and permissions. Hidden implementation subagents do not count.

Can the built-in assistant connect out to external tools or MCP servers you configure?

Not found
Nothing in the docs settles this.
Claude nothing found · GPT nothing found · Gemini nothing found
Grading standard

The vendor documents attaching an outside capability to its own AI. Shipping an MCP server is the opposite direction and a different row.

Can the product's AI find and fix BI content affected by a change in the data or its definitions?

Partlypreview
Quoted from BigQuery’s docsUnderstand the downstream consequences of modifying or dropping an asset.
Source: docs.cloud.google.com/bigquery/docs/use-cloud-assist · checked Oct 26, 2026 · quoted by Claude
Claude partly (preview) · GPT partly (preview) · Gemini partly (preview)
Grading standard

When a column is renamed, a table changes or a shared definition is edited, the product's AI or a built-in agent identifies the BI content affected and repairs it or flags it for an owner. yes: both finding the affected content and repairing or flagging it are documented for the AI. Impact analysis a person runs, with no AI involvement, does not count; the AI fixing one broken chart a user points it at is partly.

Generated apps 4

Can the built-in assistant read a generated app?

Not found
Nothing in the docs settles this.
Claude nothing found · GPT nothing found · Gemini nothing found
Grading standard

The assistant can see the app that exists, its code, its layout, what it renders.

Can the built-in assistant build a persistent governed app backed by live data?

Partlypreview

The same interface, authored from outside the product.

Evaluation & correctness 5

Can you test whether the built-in assistant's answers are right, a saved set of cases, a rubric, or a judge?

Yes
Quoted from BigQuery’s docsEvalBench acts as an automated unit-testing suite, letting you set up multi-turn scenarios, add LLM-backed and deterministic scorers, and manage the lifecycle of your Dataform pipelines.
Claude partly · GPT yes · Gemini yes
Grading standard

A saved set of questions with expected answers, a rubric, a model judging the output, or a run you can repeat after a change, applied to the built-in assistant's answers. A thumbs-up button collects opinions and does not count.

Can you pin which model version the built-in assistant uses?

Partly
Quoted from BigQuery’s docsIn the Model section, choose which types of models are available to users in a conversation with the agent.
Source: docs.cloud.google.com/bigquery/docs/create-data-agents · checked Oct 26, 2026 · quoted by Claude
Claude partly · GPT partly · Gemini partly
Grading standard

yes: an admin or user can choose a specific named model version for the built-in assistant and it stays on that version until changed. Choosing among models or providers without a fixed version is partly. The vendor managing the model with no customer choice is no. Provider choice for data location belongs to KEY, not this. Identical answers are not required.

Can you preserve the inputs, configuration and logic needed to reproduce or audit a built-in assistant answer?

Partly
Quoted from BigQuery’s docsResults from questions in a conversation persist even if the underlying data sources are deleted.
Source: docs.cloud.google.com/bigquery/docs/create-conversations · checked Oct 26, 2026 · quoted by GPT
Claude partly · GPT partly · Gemini partly
Grading standard

The product preserves the inputs, configuration, model and analytical logic needed to reproduce or audit an answer. Byte-for-byte model determinism is not required. Kept chat history with the generated query is partly; yes needs the inputs, configuration, model and logic. A record that keeps the model, the prompt and the generated query but not the data snapshot or configuration is partly.

Does a person’s correction to a built-in assistant answer change its later answers, and does the documentation say how far that reaches?

Partly
Quoted from BigQuery’s docsIf the response is not what you expect, change the settings in the Editor section to refine the data agent configuration until you get satisfactory responses.
Source: docs.cloud.google.com/bigquery/docs/create-data-agents · checked Oct 26, 2026 · quoted by Claude
Claude partly · GPT partly · Gemini yes
Grading standard

The documentation says a correction a person makes to a built-in assistant answer changes the assistant’s later answers, and says how far it reaches (that user, a team, everyone using the data). A correction documented to affect later answers with no stated reach is partly. A feedback thumb that only rates an answer or files a ticket is not this.

Does the built-in assistant answer consistently with the product's certified or governed content?

Yes
Quoted from BigQuery’s docsIf an agent can use a verified query to answer a question that you ask it, to ensure a trustworthy answer, the agent invokes the query exactly as written.
Source: docs.cloud.google.com/bigquery/docs/create-data-agents · checked Oct 26, 2026 · quoted by Claude
Claude yes · GPT yes · Gemini yes
Grading standard

When a question is already answered by certified BI content or a governed metric, the product makes the assistant use that same definition, or tells the user when its answer departs from it. yes: the documentation says the assistant is bound to or checked against certified content or governed metrics, and that a mismatch is prevented or flagged. Using the semantic layer when one exists, with no statement about certified content or mismatches, is partly (that alone is the shared-definitions read row, M_IR). A "verified" badge on some answers with no rule tying answers to certified definitions is partly.

Administration & observability 6

Can you cap what the built-in AI spends?

Yes
Quoted from BigQuery’s docsIf the estimated bytes to be scanned exceed the big_query_max_billed_bytes value, the query fails without incurring a charge, and the agent returns an error message.
Claude yes · GPT partly · Gemini yes
Grading standard

A limit that actually blocks the built-in AI's usage once it is reached. Reporting on spend without blocking anything does not count.

Can customers measure the built-in AI’s response time on their own workload by agent, model or evaluation run?

Yespreview
Quoted from BigQuery’s docsAgent metrics include agent usage, model calls, tool usage, health, latency, and token usage.
Source: docs.cloud.google.com/bigquery/docs/create-data-agents · checked Oct 26, 2026 · quoted by Claude
Claude yes (preview) · GPT yes (preview) · Gemini yes
Grading standard

Customers can measure response time on their own workload by agent, model or evaluation run. Marketing estimates and generic timeouts do not count.

Can you see built-in AI consumption broken down by user, team or workspace?

Partly
Quoted from BigQuery’s docsFilter your billing report by label to understand agent costs.
Source: docs.cloud.google.com/bigquery/docs/conversational-analytics · checked Oct 26, 2026 · quoted by Claude
Claude partly · GPT partly · Gemini yes
Grading standard

Per-user or per-team attribution of AI usage. A single tenant-wide total is not this.

Are the built-in assistant’s actions logged with the user and the analytical objects affected?

Yes
Quoted from BigQuery’s docs- Audit agent activity.
Source: docs.cloud.google.com/bigquery/docs/conversational-analytics · checked Oct 26, 2026 · quoted by Gemini
Claude partly · GPT yes · Gemini yes
Grading standard

The product records what the built-in assistant did, the prompt or query it ran and the objects it touched, attributable to the user who asked. A general product audit log that does not distinguish assistant activity is insufficient.

Can an administrator enable or disable AI features for particular users, groups or workspaces?

Yes
Quoted from BigQuery’s docsTo prevent a user from using Gemini in BigQuery features, revoke the specific cloudaicompanion IAM permissions that grant access to these capabilities, as detailed in Enable necessary APIs and grant roles.
Source: docs.cloud.google.com/bigquery/docs/gemini-set-up · checked Oct 26, 2026 · quoted by GPT
Claude yes · GPT yes · Gemini yes
Grading standard

A documented control that turns AI features on or off for a subset of the tenant. An account-wide on/off with no granularity is partly; a setting that only governs which model is used is MODELPIN, not this.

Can the built-in assistant’s change to a governed analytical asset be held for human approval before it takes effect?

Partly
Quoted from BigQuery’s docs- To place the data agent in draft mode, which you can re-edit later, click arrow_back Go back to return to the Agent Catalog page. Because your agent is now in draft mode, it appears in the My draft agents section on the Agent Catalog tab.
Source: docs.cloud.google.com/bigquery/docs/create-data-agents · checked Oct 26, 2026 · quoted by GPT
Claude partly · GPT partly · Gemini partly
Grading standard

yes: the built-in assistant's change to governed BI content or shared definitions is held until a named person or role approves it, or a policy routes the assistant's write to an approver who is a different person or role from whoever asked. A prompt shown only to the requester is partly. A draft the same user later publishes, or a general publishing workflow the assistant is not documented to enter, is partly. A user accepting or rejecting the assistant's suggestion to their own work is not approval.

Data handling & AI governance 6

Can the customer control where model inference occurs?

Partly
Quoted from BigQuery’s docsFor most Gemini in BigQuery features, the Gemini processing location can be controlled by an administrator by using the Global Default Location setting at the project or organization level.
Source: docs.cloud.google.com/bigquery/docs/gemini-locations · checked Oct 26, 2026 · quoted by Claude
Claude partly · GPT partly · Gemini yes
Grading standard

The customer controls where inference occurs. A model running in the customer's cloud, warehouse or tenant earns yes; a documented choice of region or provider endpoint, or a bring-your-own-key path where the documentation says where the provider processes the request, earns partly. Vendor-hosted inference that the documentation says the customer cannot choose or move earns no. Supplying a key does not by itself say where inference runs, and documentation that only states where processing happens, with no customer choice, belongs to the residency row. A choice that applies to only some of the product's AI features is partly.

Do your existing row-level security and column permissions apply to what the BUILT-IN assistant returns?

Yes
Quoted from BigQuery’s docsWhen a user interacts with an agent, the API queries the connected data source by using that user's credentials.
Claude yes · GPT yes · Gemini yes
Grading standard

yes: the documentation states that the built-in assistant answers under the asking user's identity, so existing row-level and column-level rules apply. Dataset-level or object-level permissions only, or row and column rules that some AI surfaces documentedly bypass, are partly.

Does the product documentation say which services receive AI prompts or data, and what they receive?

Yes
Quoted from BigQuery’s docsWhen a user uses Gemini in BigQuery, a prompt and its relevant context are sent to Google's large language models (LLMs) for processing.
Source: docs.cloud.google.com/bigquery/docs/gemini-security-privacy-compliance · checked Oct 26, 2026 · quoted by Claude
Claude yes · GPT partly · Gemini yes
Grading standard

yes: names the services that receive AI prompts or data, what they receive, and how long it is kept. Missing any one of the three is partly. A subprocessor list is not required; one published only on a separate trust or legal site is outside this documentation, so its absence here is nothing found, not no.

Does the product documentation say where AI requests are processed and stored?

Partly
Quoted from BigQuery’s docsFor these features, Gemini processing occurs in the jurisdictional boundaries of the query location, or where the BigQuery dataset is stored.
Source: docs.cloud.google.com/bigquery/docs/gemini-locations · checked Oct 26, 2026 · quoted by Claude
Claude partly · GPT partly · Gemini partly
Grading standard

yes: the product documentation states the regions where AI requests are processed and where AI data is stored, for all of the product's AI features. A subprocessor or trust page counts if it is part of the product documentation. Regions for some AI features only, or processing without storage, is partly. Terms published only on a separate trust or legal site outside this documentation are not evidence, so their absence here is nothing found, not no.

Does the vendor state your data is not used to train AI models, by default?

Yes
Quoted from BigQuery’s docsGemini in BigQuery doesn't use your data to train or fine-tune its models.
Source: docs.cloud.google.com/bigquery/docs/gemini-overview · checked Oct 26, 2026 · quoted by Claude
Claude yes · GPT yes · Gemini yes
Grading standard

A statement that customer data is not used to train AI models by default. An opt-out you have to find is weaker and should be partly.

Can an administrator restrict which data the assistant may use, separately from user permissions?

Partlypreview
Quoted from BigQuery’s docsTable selection isn't a security setting.
Claude partly · GPT partly · Gemini partly (preview)
Grading standard

yes: an administrator can enforce, across the workspace or tenant, a limit on which data the assistant may use, separate from user permissions. A scope the author of each agent sets, or a scope the documentation says is not a security boundary, is partly.

Agent access 13

Can an outside agent act under an identity or token scoped narrower than the human's own access?

Yes
Quoted from BigQuery’s docsWe recommend that you create a separate identity for agents that are using MCP tools so that access to resources can be controlled and monitored.
Source: docs.cloud.google.com/bigquery/docs/use-bigquery-mcp · checked Oct 26, 2026 · quoted by Claude
Claude yes · GPT yes · Gemini yes
Grading standard

yes: an outside agent can act under an identity or token scoped narrower than the human's own access (read-only, limited objects or limited tools). Acting as the full human identity is partly. Shared broad credentials do not count.

Can an outside agent traverse the upstream sources and transformations behind a number?

Partly
Quoted from BigQuery’s docsVIEW: A virtual table defined by a SQL query.
Source: docs.cloud.google.com/bigquery/docs/reference/mcp/tools_list/get_table_info · checked Oct 26, 2026 · quoted by Claude
Claude partly · GPT partly · Gemini partly
Grading standard

yes: an outside agent can follow a number to its upstream sources and transformations through a documented lineage interface. Reading the SQL of a view or model and inferring its sources is partly. A link from an answer back to its underlying source is partly. A description that names no upstream source or transformation does not count.

Are an outside agent’s actions logged with its identity and the analytical objects affected?

Yes
Quoted from BigQuery’s docsQueries executed using the execute_sql tool will always have the default job label goog-mcp-server: true automatically set in addition to any custom labels provided in the request.
Source: docs.cloud.google.com/bigquery/docs/reference/mcp · checked Oct 26, 2026 · quoted by Claude
Claude yes · GPT yes · Gemini yes
Grading standard

The product records actions taken by an outside agent, tied to its delegated identity and affected analytical objects. A general user activity log is insufficient.

Can an outside agent’s change to a governed analytical asset be held for human approval?

Not found
Nothing in the docs settles this.
Claude nothing found · GPT partly · Gemini nothing found

yes: an outside agent's change to governed BI content or shared definitions is held until a named person or role approves it, or an MCP or agent policy routes the agent's write to an approver who is a different person or role from whoever started the agent. A prompt shown only to the requester is partly. A draft the same user later publishes, or a general Git pull-request workflow not documented for agent changes, is partly.

Can a reviewer see a diff of what an outside agent changed in a governed analytical asset?

Partly

A reviewer can see a before/after diff of changes an outside agent made to a governed analytical asset. A generic publish or change diff is partly; yes needs the documentation to show it covers changes made by an outside agent.

Can an outside agent’s change to a governed analytical asset be rolled back?

Partly

A change made by an outside agent to a governed analytical asset can be reverted or restored.

Does the vendor support an MCP server with documented authentication for outside agents?

Yes
Quoted from BigQuery’s docsBigQuery MCP servers use the OAuth 2.0 protocol with IAM for authentication and authorization.

Grading standard

A vendor-supported MCP server gives outside agents access to the customer’s analytical objects or data, with documented authentication and no customer-built middleware. A vendor-supported server the customer operates, or one in preview, earns partly. A server built by the community or by customers, or one that only searches documentation, does not count.

Can an outside agent list what exists, dashboards, metrics, tables, without being told what to look for?

Yes
Quoted from BigQuery’s docsList table ids in a BigQuery dataset or BigLake namespace.

Claude yes · GPT yes · Gemini yes
Grading standard

A documented way to enumerate objects, not just fetch one by id. Reading a named dashboard is a different row; this is finding out the dashboard is there.

Does the vendor document how an outside agent authenticates, a service account, a token, or acting on behalf of a user?

Yes
Quoted from BigQuery’s docsAuthentication details: depending on how you want to authenticate, you can enter your Google Cloud credentials, your OAuth Client ID and secret, or an agent identity and credentials.

A named credential type for programmatic access. Whose permissions apply is a different row; this is how the agent gets in at all.

Does the vendor publish skills or packaged instructions that teach an outside agent to use the product?

Yes
Quoted from BigQuery’s docsBigQuery provides agent skills that can help your agent accomplish common tasks.

Claude yes · GPT yes · Gemini yes
Grading standard

A vendor-published skill, plugin or instruction pack (for example a SKILL.md or an agent plugin) that an outside coding agent loads to use the product well. Documentation of an MCP server alone is the MCP server row, not this.

Is there a command-line tool documented for use by outside agents?

Business context 8

Can you teach the AI about your business?

Yes
Quoted from BigQuery’s docs- Context. A data agent for sales analysis can be configured to understand that "top performers" refers to sales representatives with the highest revenue, rather than just the most closed deals.

Somewhere to write down what the schema does not say: which customers count as active, which of the three revenue tables is authoritative, what finance means by bookings. The AI reads it before answering.

Can the business context you give the AI live in version control?

Yes
Quoted from BigQuery’s docsYou can create agent instruction files to use in your local workspace, or you can use the same instruction files across multiple data pipelines with an external repository.

The business context lives in files you can diff, review and roll back.

Can different teams get different business context for the AI, rather than one global set?

Yes
Quoted from BigQuery’s docsIf your agent requires more than 20 data sources, is used across teams that have different metric definitions, or prioritizes one type of result at the expense of another, consider creating additional agents.

Context attached to a workspace, team, audience or model rather than the whole tenant.

Is there a way to validate business context before it affects the AI’s answers?

Yes
Quoted from BigQuery’s docs- In the Preview section, type an example user question in the Ask a question field, and then press Enter. To verify that the data agent returns the data that you expect, review the agent's response. If the response is not what you expect, change the settings in the Editor section to refine the data agent configuration until you get satisfactory responses. You can continue to test and modify your agent to refine the agent's results.

yes: a product setting that removes a table, field or answer from the AI's reach, or marks it deprecated so the AI avoids it, specific to the AI. An instruction in the AI's context telling it not to use something is partly. Ordinary data permissions are AIRESTRICT or GOVBIND, not this.

Is there a documented owner or approval workflow for business context?

Partly
Quoted from BigQuery’s docsTo edit, share, or delete a data agent: Gemini Data Analytics Data Agent Owner (roles/geminidataanalytics.dataAgentOwner) on the agent or project.

Claude partly · GPT partly · Gemini partly
Grading standard

yes: the documentation names who owns or approves business context (a role or person) and describes a review or approval step for changes to it. A named owner role with no review step, or a review workflow with no named owner, is partly. Edit permissions alone are not this.

Warehouse logic 5

Can the built-in assistant read logic that lives in your warehouse?

Grading standard

yes: the product documents a direct path from a calculation written for one chart or analysis to a maintained shared definition, without a developer rewriting it. A path that needs the calculation re-expressed by a developer (for example in a modeling language) is partly. Reusing logic that already exists as a shared definition, macro or snippet does not count.
