MCP server for Langfuse LLM observability — trace and observation analysis.

Install

The sweep installs into a clean prefix, but this is the command a user would run:

npx langfuse-observability-mcp-server

Needs credentials: LANGFUSE_SECRET_KEY, LANGFUSE_PUBLIC_KEY. The probe used placeholder values, so an amber needs credentials result below means the server asked for the real ones, not that it is broken. Maintainers: how to go green.
