Best Google BigQuery MCP Servers
Google BigQuery is a fully-managed, serverless data warehouse that enables scalable analysis over petabytes of data. It is a Platform as a Service that supports querying using ANSI SQL.
Why this server?
Provides read-only access to Google BigQuery, enabling discovery of datasets, tables, schemas, partitioning, freshness, scheduled queries, notebooks and code assets, and execution of validated SELECT queries under the user's Google credentials.
AlicenseAqualityBmaintenanceA read-only Model Context Protocol server over Google BigQuery that lets AI clients answer plain-language data questions by discovering schemas, inspecting table freshness and code assets, and running validated SELECT queries under the user's own Google credentials.1422 PyPI2MITWhy this server?
