Logfire MCP Server

This repository hosts a Model Context Protocol (MCP) server designed to access OpenTelemetry traces and metrics sent to Logfire, enabling LLMs to analyze application telemetry data, distributed traces, and SQL query results via Logfire APIs.

Available Tools: The server offers tools like find_exceptions (exception counts by file), find_exceptions_in_file (detailed trace info for file exceptions), arbitrary_query (custom SQL queries), and get_logfire_records_schema (OpenTelemetry schema).

Setup: Requires uv for running the server. A Logfire read token is needed, obtainable from the Logfire project settings. The server can be run manually using uvx with the LOGFIRE_READ_TOKEN environment variable or --read-token flag.

Configuration: Instructions are provided for configuring the server with Cursor, Claude Desktop, and Cline, including JSON configuration examples. The base URL for the Logfire API can be customized using the --base-url argument or the LOGFIRE_BASE_URL environment variable.
