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

Unity MCP Server — questions

Answers built from our own checks of this server.

Why is there no uptime for Unity MCP Server?

Unity MCP 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 unity-mcp-server was installed 142 times last week.

How do I connect Unity MCP 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 unity-mcp-server straight from npm; nothing to host, nothing to sign up for.

How many people use Unity MCP Server?

The npm package unity-mcp-server was installed 142 times in the last week. Week over week that is -37%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Unity MCP Server open source?

We cannot say either way: written in TypeScript and 5 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
