Langfuse open-sources MCP Server to debug agent runs without raw telemetry
blaizedsouza · x · 2026-09-29
Dan Kornas released Langfuse MCP Server, a local Model Context Protocol server and agent skill for builders using Langfuse to inspect agent runs—so debugging failures no longer means digging through raw telemetry.
Key features:
- Trace inspection: fetch individual traces and observations on demand
- Exception triage: group recent errors, inspect files, pull exception details
- Session analysis: retrieve session/user data to investigate runs over time
- Token-aware output: compact summaries, truncation, or file dumps to control response size
- Narrower access: load only needed tool groups or enable read-only mode
MIT-licensed and open source, usable from any MCP client.
