Fastmcp Server

You get 30 reference files covering everything from basic tool decorators to production concerns like OAuth authentication, middleware pipelines, OpenTelemetry tracing, and custom providers. The skill walks through context objects for progress reporting and resource access, dependency injection patterns, and four different auth strategies including OIDC proxy and full OAuth servers. If you're writing a new MCP server or upgrading from 2.x, this consolidates the API patterns and deployment options in one place so you're not hunting through scattered docs.
