Build Your MCP server
summary
Hands-on workshop builds an MCP server from scratch to expose concrete tools — examples include read unread emails and send email — using the FastMCP SDK and an OpenAI model, connecting Gmail via SMTP and an app password. An MCP inspector runs on ports 6274/6277, transport follows JSON-RPC 2.0, and ngrok is shown for public endpoints. The demo composes persona-driven replies and successfully reads, generates, and sends emails end-to-end.
