FAQ from MCP Server Suite: Calculator + Gmail Integration

What are the prerequisites?

Python 3.12 or higher, Claude Desktop MCP Client, and a Google Cloud Platform account with the Gmail API enabled.

How is authentication handled for Gmail?

The Gmail server uses OAuth 2.0 with a client credentials file and token file; tokens are stored securely in a user-specified location.

Does the server support sending emails with calculations?

Yes. The workflow demonstrates asking Claude to calculate an expression and then requesting to send the result to an email address; the server drafts an email and asks for confirmation before sending.

How are the calculator and Gmail servers started?

Start the calculator server by running python math-mcp-server/mcp_server.py inside the calculator directory. Start the Gmail server by running python src/gmail/server.py with --creds-file-path and --token-path arguments.
