Rune MCP Server

Most tools scan your codebase once, hand your AI a snapshot, and go stale the moment you save a file. Rune doesn't scan - it runs. Always on, always watching, always up to date. It runs locally over stdio via the published package.

People connecting coding agent tools to Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "thecolourfoundation-rune": {
      "command": "npx",
      "args": [
        "-y",
        "@moosl/rune"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

repo age created 2026-07-29 - young repo, little track record yet

license MIT - declared in the repository

npm package @moosl/rune - the @moosl scope differs from the repo owner (thecolourfoundation); confirm it's the project's official package

registry namespace io.github.thecolourfoundation is GitHub-verified and matches the repo owner
