Mcp Firebird

What is Mcp Firebird?

Mcp Firebird is a server that implements Anthropic's Model Context Protocol (MCP) for Firebird SQL databases. It enables Large Language Models (LLMs) like Claude to securely access, analyze, and manipulate data in Firebird databases.

How to use Mcp Firebird?

Install globally or locally via npm (npm install -g mcp-firebird or npm install mcp-firebird). Configure using environment variables (FIREBIRD_HOST, FIREBIRD_PORT, FIREBIRD_DATABASE, FIREBIRD_USER, FIREBIRD_PASSWORD, FIREBIRD_ROLE) or run directly with npx and command-line arguments (npx mcp-firebird --host localhost --port 3050 --database /path/to/database.fdb --user SYSDBA --password masterkey). For Claude Desktop, add the server configuration to claude_desktop_config.json using absolute paths.

FAQ from Mcp Firebird

What is MCP and how does Mcp Firebird relate to it?

MCP (Model Context Protocol) is a protocol by Anthropic that allows LLMs to access external tools and data. Mcp Firebird implements this protocol specifically for Firebird databases, enabling LLMs like Claude to interact with the database.

What runtime dependencies does Mcp Firebird have?

It requires Node.js and npm to install and run. The server is launched as a child process using npx.

Where does the data live when using Mcp Firebird?

All data remains in the Firebird database specified via the --database argument or FIREBIRD_DATABASE environment variable. The server only reads and writes to that database.

What authentication is supported?

Authentication is handled via a Firebird username and password (FIREBIRD_USER / FIREBIRD_PASSWORD). An optional FIREBIRD_ROLE can also be set.

How does the server transport data?

The server communicates over standard input/output (stdin/stdout) as a child process, following the MCP transport contract. The README examples show usage with ChildProcessTransport in TypeScript and subprocess.Popen in Python.
