How to Set Up and Use Multi Chat
Multi-Chat MCP Server connects AI assistants like Claude and Cursor directly to Google Chat, enabling them to search messages, send replies, manage spaces, and participate in team conversations in real time. It uses OAuth 2.0 to authenticate with your Google Workspace account and surfaces a rich set of space management, messaging, and file-sharing capabilities as MCP tools. Teams use it to let AI summarize channel activity, search historical discussions, and help coordinate across multiple chat threads — all from within their AI coding assistant.
Prerequisites
- Python 3.9+ with uv or pip installed
- A Google Workspace account with Google Chat API enabled
- Google OAuth 2.0 credentials (credentials.json) downloaded from Google Cloud Console
- An MCP-compatible client such as Claude Desktop or Cursor
Clone the repository and install dependencies
Clone the multi-chat-mcp-server repository and create a virtual environment using uv, then install all Python requirements.
git clone https://github.com/siva010928/multi-chat-mcp-server.git
cd multi-chat-mcp-server
uv venv .venv
source .venv/bin/activate
uv pip install -r requirements.txtConfigure Google Cloud credentials
Download OAuth 2.0 credentials from the Google Cloud Console for the Chat API. Place the credentials.json file in the project root, then update provider-config.yaml to point to it.
# provider-config.yaml
providers:
google_chat:
name: "Google Chat"
token_path: ".token"
credentials_path: "credentials.json"
callback_url: "http://localhost:8080"Authenticate with Google Chat
Run the local auth flow to grant the server access to your Google Workspace account. This opens a browser window for the OAuth consent screen and stores an access token.
python -m src.server --provider google_chat --local-authConfigure your MCP client
Add the server entry to your Claude Desktop or Cursor MCP configuration file, pointing to your local clone directory.

"mcpServers": {
"google_chat_mcp": {
"command": "uv",
"args": [
"--directory", "/path/to/multi-chat-mcp-server",
"run", "-m", "src.server",
"--provider", "google_chat"
]
}
}
}Restart your MCP client and verify
Restart Claude Desktop or reload the Cursor window. The server should appear connected and you can test it by asking Claude to list your Google Chat spaces.

OAuth error: redirect_uri_mismatch during local auth
In the Google Cloud Console, add http://localhost:8080 as an authorized redirect URI for your OAuth 2.0 client ID. Ensure the callback_url in provider-config.yaml matches exactly.
Server starts but Claude cannot list spaces
Verify that the Google Chat API is enabled in your Google Cloud project under APIs & Services. Also confirm the token file was created at the path specified by token_path after running --local-auth.
