What is this?

vrchat-udon-mcp is a stdio MCP server that indexes, searches, and validates UdonSharp documentation from the agent-skills-vrc-udon repository at runtime. No hardcoded docs — the remote repo is the single source of truth.

Quick start

git clone https://github.com/MauDevVR/vrchat-udon-mcp.git
cd vrchat-udon-mcp
pnpm install
pnpm update-docs && pnpm build-index && pnpm build
pnpm start

MCP config (Cursor / Claude — relative paths only):

{
  "mcpServers": {
    "vrchat-udon": {
      "command": "node",
      "args": ["${workspaceFolder}/dist/index.js"]
    }
  }
}

See docs/mcp-config.example.json and the language READMEs for npx, global install, submodule, and git dependency options.
