Agent Observability runs on your own machine — the client starts it, so there is no endpoint to ping. 198 installs a week from pypi. Last commit 25 Aug 2026.
AI agent observability with deterministic record/replay for debugging agent failures.
What the code does
We read the source, 11 h ago · rules 3dff92dd89df
What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.
return spawnSync(command, commandArgs, {
result = subprocess.run(command, env=env, check=False) # noqa: S603

This code can reach further than it looks
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
