Today is the operative word: we check Heddle every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Heddle — questions

Answers built from our own checks of this server.

Why is there no uptime for Heddle?

Heddle 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 heddle-mcp was installed 73 times last week.

How do I connect Heddle?

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 heddle-mcp straight from pypi; nothing to host, nothing to sign up for.

How many people use Heddle?

The pypi package heddle-mcp was installed 73 times in the last week. Week over week that is -45%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Heddle open source?

Yes — it is published under the Apache-2.0 licence, written in Python, 2 stars on GitHub and 2 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
