This project is a Model Context Protocol (MCP) server for interacting with the VRChat API. It allows you to retrieve various information from VRChat using a standardized protocol.
Overview
The VRChat MCP server provides a way to access VRChat's API endpoints in a structured manner. It supports a wide range of functionalities, including user authentication, retrieving user and friend information, accessing avatar and world data, and more.
Usage
To start the server, ensure you have the necessary environment variables set:
export VRCHAT_USERNAME=your_username
export VRCHAT_AUTH_TOKEN=your_auth_token
[!NOTE]
How to obtain AUTH TOKEN
You can use the following command to login and obtain an auth token:
$ npx vrchat-auth-token-checker VRChat Username: your-username Password: ******** # If 2FA is enabled 2FA Code: 123456 # Success output Auth Token: authcookie-xxxxxPlease handle the obtained token with care as it has a very long lifetime
Then, run the following command:
npx vrchat-mcp
This will launch the MCP server, allowing you to interact with the VRChat API through the defined tools.
Usage with Claude Desktop
To use this MCP server with Claude Desktop, you do not need to run npx vrchat-mcp manually. Instead, add the following configuration to your Claude Desktop config file:
- MacOS:
~/Library/Application Support/Claude/claude_desktop_config.json - Windows:
%APPDATA%\Claude\claude_desktop_config.json
{
"mcpServers": {
"vrchat-mcp": {
"command": "npx",
"args": ["vrchat-mcp"],
"env": {
"VRCHAT_USERNAME": "your-username",
"VRCHAT_AUTH_TOKEN": "your-auth-token"
}
}
}
}
Then, start Claude Desktop as usual. If you have to use nodenv or nvm, you may need to specify the full path to the npx command.

Debugging
First, build the project:
npm install
npm run build
Since MCP servers run over stdio, debugging can be challenging. For the best debugging experience, we strongly recommend using the MCP Inspector.
You can launch the MCP Inspector via npm with this command:
npx @modelcontextprotocol/inspector "./dist/main.js"
Be sure that environment variables are properly configured.
Upon launching, the Inspector will display a URL that you can access in your browser to begin debugging.
