MCP Composer — questions

Answers built from our own checks of this server.

Why is there no uptime for MCP Composer?

MCP Composer 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 @oaslananka/composer.

How do I connect MCP Composer?

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 @oaslananka/composer straight from npm; nothing to host, nothing to sign up for.

Is MCP Composer open source?

Yes — it is published under the Apache-2.0 licence, written in TypeScript, 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.
