BigQuery Data Platform

io.github.deBilla/data-platform-mcpv0.4.0Databases

Read-only BigQuery tools for plain-language data questions, with a cost gate on every query

The current version, v0.4.0, was published to the official MCP registry on 2026-09-22. It is distributed as data-platform-mcp on PyPI, filed under Databases by this index, and declares 11 environment variables. Removals and unreachable sources are measured across every server this index tracks, contract drift across the servers that answer in consecutive snapshots; the index's current counts put this record in context.

In-path gate · all MCP tools

Using BigQuery Data Platform in Claude, Cursor, Gemini CLI, Cline, or Zed?

MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).

Install the mcpindex gate (one command)

Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

Limits of this verdict

- Semantic screen only - the deterministic conformance probe has not run on this server
- Confidence is reported but not yet calibrated (v1)
- Screen reads the tool description, not the live behavior
- advisory
- registry description only no input schema
- screen model 8b
- Still current: the description we screened is unchanged, re-checked against the registry
- The registry listing (version, packages, links) changed after this screen ran - the description we assessed did not

Semantic screen: an LLM judge reads the tool description for hidden instructions (status PARTIAL). A pass means the description is not lying, not that the tool is safe: a high-capability tool with an honest description still warrants caution. The deterministic conformance probe has not been run on this server yet, so the screen here is semantic-only. Posture: advisory. Confidences are reported but not yet calibrated (calibrated=false at v1). Full verdict history is not shown on this page.

Own this server? Test a description on the public screen → It is a separate check from the verdict above, so the two can differ.

That verdict was true at screening time (snapshot 2026-10-19).

Contracts can change after screening, with no version bump. The gate pins BigQuery Data Platform’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

Cite this record

People vet a server before wiring it in. One line on your project site or docs answers that with an independent record: screening verdict, registry provenance, contract drift history. It stays current as new screens and drift events land.

Environment variables

BQ_MCP_ENVIRONMENTS

JSON map of environment name to BigQuery settings (project, location, impersonate, dataset_allowlist, byte caps). Omit when using a config file at ~/.config/data-platform-mcp/config.toml.

BQ_MCP_DEFAULT_ENVIRONMENT

Environment used when a tool call omits the environment argument.

BQ_MCP_CONFIG

Path to a TOML config file, overriding ~/.config/data-platform-mcp/config.toml.

BQ_IMPERSONATE_SERVICE_ACCOUNT

Read-only service account to impersonate, making read-only a property of the identity rather than of this code. Create it with `data-platform-mcp setup`.

BQ_PROJECT

GCP project whose BigQuery datasets are queried. Falls back to the project associated with Application Default Credentials.

BQ_LOCATION

BigQuery location for jobs and datasets. Defaults to US.

BQ_CODE_ASSET_LOCATION

Region holding BigQuery Studio notebooks and saved queries. Separate from BQ_LOCATION and usually different: code assets are regional and Dataform rejects multi-regions, so datasets in US typically pair with code assets in a region like us-central1. A wrong region returns an empty list rather than an error. Defaults to BQ_LOCATION.

BQ_DATASET_ALLOWLIST

Comma-separated dataset IDs the server may read. Empty means all datasets.

BQ_WARN_BYTES

Scan size above which a query is returned for user confirmation instead of run. Defaults to 1 GiB.

BQ_MAX_BYTES_BILLED

Hard per-query scan cap; a query estimated above this never runs. Defaults to 5 GiB.

BQ_MCP_AUDIT_LOG

Path for the JSONL tool-call audit log, or 'off' to disable it. SQL text is never recorded, only a hash and a length.

Verdict API

Provenance

Each verdict is bound to a hash of the exact description it judged, so a re-crawl that changes the text produces a new record rather than silently inheriting this one. Verdict history is hash-chained and anchored to Bitcoin via OpenTimestamps (latest confirmed at block 972,115). Verify it yourself.
