MCP Reference Server — questions

Answers built from our own checks of this server.

Why is there no uptime for MCP Reference Server?
MCP Reference Server 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 mcp-reference-server.
How do I connect MCP Reference Server?
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 mcp-reference-server straight from npm; nothing to host, nothing to sign up for.
Is MCP Reference Server open source?
We cannot say either way: 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
