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

This one needs environment variables set before it will start: RXN_API_KEY (IBM RXN key for retrosynthesis (free)), ROWAN_API_KEY (Rowan key for pKa/NMR predictions (free)). The author declared them in the registry entry; get the values from the project itself.

Labmate MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Labmate MCP?

Labmate MCP 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 labmate-mcp was installed 128 times last week.

How do I connect Labmate MCP?

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

How many people use Labmate MCP?

The pypi package labmate-mcp was installed 128 times in the last week. Week over week that is +1%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Labmate MCP open source?

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