Which BigQuery MCP server should you use?

BigQuery bills by bytes scanned, so an agent writing exploratory queries can get expensive. Prefer servers that dry-run queries or cap maximum bytes billed, and point them at partitioned tables.

Use a service account with BigQuery Data Viewer and Job User roles on specific datasets instead of project-wide editor access.

Frequently asked questions about BigQuery MCP servers

What is the best BigQuery MCP server?

This page ranks BigQuery MCP servers with servers we have seen run first, then by popularity. Prefer servers that support dry runs or byte limits to keep query costs predictable.

How do I limit BigQuery costs when an agent runs queries?

Set a maximum bytes billed limit, give the service account access only to needed datasets, and use a server that dry-runs queries to estimate cost before executing.

What credentials does a BigQuery MCP server need?

Usually a Google Cloud service account key or application default credentials, with read and job-run roles on the datasets the agent should query.
