An Elixir library providing an implementation of the Model Context Protocol (MCP) over Server-Sent Events (SSE). It includes SSE connection management, JSON-RPC message handling, tool registration and execution, session management, and automatic ping/keepalive; developers implement the MCPServer behaviour callbacks to build their own MCP server, including within Phoenix or Plug applications.
