Colregs MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Colregs MCP?

Colregs 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 npm package colregs-mcp was installed 498 times last week.

How do I connect Colregs MCP?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls colregs-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use Colregs MCP?

The npm package colregs-mcp was installed 498 times in the last week. Week over week that is +740%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Colregs MCP open source?

Yes — it is published under the AGPL-3.0 licence, written in TypeScript, 0 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.
