Firebase MCP

Google ships an official MCP server as part of the Firebase CLI, turning a Firebase project's backend services into tools an AI coding assistant can call. Instead of guessing at your data model or SDK surface, the agent reads real project state: it lists Firestore collections and documents, inspects security rules, looks up Authentication users, browses Cloud Storage buckets, reads Remote Config parameters and pulls Crashlytics issue reports for a specific app. Write actions round out the loop. An agent can create and update Firestore documents, set custom claims on a user, deploy rules, update Remote Config templates and scaffold new apps inside a project. Tools are organized into feature groups, so you can start the server with only the services a given task needs and keep everything else out of reach. It runs locally over stdio through the Firebase CLI and reuses the credentials from your existing CLI login, so there is no separate key to provision or rotate. The intended audience is mobile and web developers already building on Firebase who want an assistant grounded in their actual project rather than generic documentation: debugging a crash against live Crashlytics data, working out why a query is blocked by a rule, or seeding realistic test records.
