flamerobin-mcp-server

A Model Context Protocol (MCP) server for Firebird databases intended for local use. It reads connection details from FlameRobin's fr_databases.conf so no extra configuration is needed — if you have FlameRobin set up with your Firebird databases, this server works out of the box.

Compared to mcpFirebird

Building

dotnet build FirebirdMcp.csproj

Publishing a single self-contained executable

dotnet publish FirebirdMcp.csproj -c Release -r win-x64 --self-contained true -p:PublishSingleFile=true -p:IncludeNativeLibrariesForSelfExtract=true -o publish-single

The output is publish-single\FirebirdMcp.exe. The publish-single\ folder is gitignored.

Claude Desktop configuration

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "firebird": {
      "command": "C:\\path\\to\\publish-single\\FirebirdMcp.exe",
      "env": {
        "Logging__LogLevel__Default": "None"
      }
    }
  }
}

Important: The Logging__LogLevel__Default=None env var is required. The server's startup log output is written to stdout, which Claude reads as part of the MCP handshake — any unexpected output causes Claude to fail to recognize the server.
