About this plugin

The plugin adds Logfire observability workflows to Python projects, detecting frameworks and helping instrument FastAPI, httpx, asyncpg, SQLAlchemy, and other supported libraries. It can query traces, logs, and metrics, investigate errors, monitor infrastructure, and add dataset-based evaluations for AI and agent behaviour.

Use it when setting up Logfire, debugging an instrumented application, exploring project data, or opening Logfire views. It authenticates with Logfire and includes an MCP server for querying Logfire data.
