BigQuery FAQs

Question 1

What is the BigQuery MCP Server?

Accepted Answer

It's a tool that allows Large Language Models (LLMs) like Claude to query and analyze your BigQuery data using natural language, providing a secure and efficient way to interact with your database.

Question 2

Which LLMs are supported?

Accepted Answer

Currently, MCP support is available as a developer preview in Claude Desktop. Connections are limited to local MCP servers running on the same machine.

Question 3

What permissions do I need?

Accepted Answer

You'll need either the `roles/bigquery.user` role or both `roles/bigquery.dataViewer` and `roles/bigquery.jobUser` roles assigned to your Google Cloud project.

Question 4

How does it work?

Accepted Answer

The server uses the Model Context Protocol (MCP) to translate natural language questions into SQL queries, which are then executed against your BigQuery dataset. It provides read-only access for enhanced security and enforces a 1GB query limit by default.

Question 5

What are the benefits of using this server?

Accepted Answer

You can query your BigQuery data using plain English, eliminating the need to write SQL queries manually. It offers enhanced security with read-only access and allows you to explore dataset schemas easily. All while staying within safe data access limits.
