An MCP (Model Context Protocol) server implementation using HTTP SSE (Server-Sent Events) connections with built-in utility tools including echo, time, calculator, and weather query functionality.
Enables MCP clients to connect over stateless Streamable HTTP and authenticate through an existing OAuth 2.1 / OpenID Connect authorization server, with JWT validation, per-tool scope enforcement, and step-up challenges. It ships example scoped tools for reading and creating per-user notes that developers replace with their own.
Enables MCP client interaction via streamable HTTP, providing example tools (echo, getPostsByUser) and resources (posts, users) with pluggable authentication providers.
