Overview
**Firebase MCP** enables AI assistants to work directly with Firebase services, including:
- **Firestore**: Document database operations
- **Storage**: File management with robust upload capabilities
- **Authentication**: User management and verification
The server works with MCP client applicatios such as Claude Desktop, Augment Code, VS Code, and Cursor.
> ⚠️ **Known Issue**: The firestore_list_collections tool may return a Zod validation error in the client logs. This is an erroneous validation error in the MCP SDK, as our investigation confirmed no boolean values are present in the response. Despite the error message, the query still works correctly and returns the proper collection data. This is a log-level error that doesn't affect functionality.
⚡ Quick Start
Prerequisites
- Firebase project with service account credentials

MCP Servers can be installed manually or at runtime via npx (recommended). How you install determines your configuration:
