Firestore MCP Server

What is Firestore MCP Server?

An MCP (Model Context Protocol) server for interacting with Google Firestore directly through Claude Desktop. It provides a clean interface for creating, reading, updating, and deleting Firestore documents, targeting developers who use Claude and need to manage Firestore data programmatically.

How to use Firestore MCP Server?

Install dependencies with npm install, build with npm run build, then configure Claude Desktop by adding the server to claude_desktop_config.json with the path to build/index.js, a GOOGLE_CLOUD_PROJECTS environment variable listing project IDs, and corresponding .json credential files in a keys folder. The service account must have Firestore permissions (e.g., Cloud Datastore Owner). Tools are invoked via natural language prompts in Claude Desktop (e.g., "Get the document with ID user123 from the users collection").
