Q&A

How can I debug the server if stdio communication is problematic?

Use the MCP Inspector by running `npm run inspector`. It launches a browser-based tool that provides a URL to monitor and debug the server’s stdio communication, simplifying troubleshooting.

The server is a JSON document store, so it only accepts and returns data in JSON format. It does not support other data types or binary blobs.

How do I integrate mcp-database-server with Claude Desktop?

Add the server config to your Claude Desktop config file (e.g., ~/Library/Application Support/Claude/claude_desktop_config.json on macOS or %APPDATA%/Claude/claude_desktop_config.json on Windows) with the command pointing to the server’s build entry point: `{ mcpServers : { fireproof : { command : /path/to/fireproof mcp/build/index.js } } }`.
