What is MCP over SSE?
MCP over SSE is a library that implements the Model Context Protocol using Server-Sent Events. It provides a way to build real-time communication between a server and client using the MCP standard.
How to use MCP over SSE?
The library can be installed in Phoenix or Plug applications. Configuration involves adding dependencies to mix.exs, configuring the router, and setting up session management. Detailed installation steps for both Phoenix and Plug (Bandit) applications are provided in the README.

FAQ from MCP over SSE
What is MCP?
What is MCP?
The Model Context Protocol (MCP) is an open standard that defines how AI models communicate and share context with other applications and services. For more infromation visit https://modelcontextprotocol.io/introduction.
What is SSE?
What is SSE?
Server-Sent Events (SSE) is a server push technology enabling a server to automatically push data updates to a client over HTTP.
How do I configure the ping interval?
How do I configure the ping interval?
You can configure the ping interval using the :mcp_sse, :sse_keepalive_timeout configuration option in your config/config.exs file. The value is in milliseconds, or set :infinity to disable pings.
How do I handle different content types in responses?
How do I handle different content types in responses?
You need to format your responses according to the MCP specification for content types (text, image, resource). The README provides examples of how to format text, image, and resource responses.
How do I manage session IDs?
How do I manage session IDs?
The library automatically manages session IDs. It uses an existing session ID from query parameters if provided or generates a new one if none exists. This ensures all requests to the /sse and /message endpoints have a valid session ID.
