Q&A

What VRChat functionalities are exposed through the MCP server’s tools?

The server provides tools for user data (friends list, send friend request), avatar operations (search and select avatars), world data (search worlds, list favorited worlds), and instance management (create and get instance info), all accessed via standardized MCP endpoints.

Asked by Ravi Chandrasekaran · May 17, 2026

Can the MCP server be integrated with Claude Desktop and how is it configured?

Yes. Add an entry in Claude Desktop’s config file (e.g., `claude_desktop_config.json`) under `mcpServers` specifying the command `npx vrchat mcp` and the required environment variables. Claude Desktop will then launch the MCP server automatically.

Asked by Pierre Dubois · Apr 12, 2026

How do I authenticate the VRChat MCP server and what credentials are required?

Set the environment variables VRCHAT_USERNAME and VRCHAT_AUTH_TOKEN before starting the server. You obtain the auth token by running `npx vrchat auth token` and entering your username, password, and any 2FA code; the token has a long lifetime.
