Mergewarden — questions

Answers built from our own checks of this server.

Why is there no uptime for Mergewarden?
Mergewarden 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 mergewarden-mcp was installed 314 times last week.
How do I connect Mergewarden?
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 mergewarden-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Mergewarden?
The npm package mergewarden-mcp was installed 314 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Mergewarden open source?
Yes — it is published under the MIT licence, written in TypeScript, 15 stars on GitHub and 11 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
