Agent Harnesses — questions

Answers built from our own checks of this server.

Why is there no uptime for Agent Harnesses?
Agent Harnesses runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package agent-harnesses-mcp was installed 546 times last week.
How do I connect Agent Harnesses?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls agent-harnesses-mcp straight from pypi; nothing to host, nothing to sign up for.
How many people use Agent Harnesses?
The pypi package agent-harnesses-mcp was installed 546 times in the last week. Week over week that is -8%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Agent Harnesses open source?
Yes — it is published under the CC-BY-SA-4.0 licence, written in Python, 458 stars on GitHub and 10 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
