Observe Instrument MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 123 installs a week from pypi. Last commit 17 Mar 2026.
Add OpenTelemetry tracing to Python AI agents. Supports LangGraph, LlamaIndex, CrewAI, OpenAI SDK.
Today is the operative word: we check Observe Instrument MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
