Google BigQuery documentation

What it does

Google Cloud's serverless data warehouse, where many RevOps teams land CRM, product and billing data for modelling and reporting; a first-party remote MCP server exposes dataset and table metadata and SQL execution to agents.

Access and connection

MCP support: official

Access requirements: free - Google's free-tier list gives BigQuery "1 TiB of querying per month" and "10 GiB of storage per month" at no charge, and the MCP docs state "The BigQuery MCP server doesn't have its own quotas" and "there is no limit on the number of calls", with usage "still subject to the quotas enforced by the APIs called by the MCP server tools". Query and storage beyond the free tier are billed at standard BigQuery rates.

Authentication: oauth. The docs state the server uses the "OAuth 2.0 protocol with IAM for authentication and authorization", supports "all Google Cloud identities" and requires the scope https://www.googleapis.com/auth/bigquery; the client sends a Google access token as a Bearer header.
