Yes, this is a fully remote MCP server, so the need for an SSE support makes the implementation quite complex. The MCP spec updated to use HTTP streaming, but clients do not support it yet.
It's very helpful when working with a specific technology/library, and you want to access the project's llms.txt, readme, search the docs, etc from within the IDE using the MCP client.
Check it out, for exmaple, with the langgraph docs: https://gitmcp.io/#github-pages-demo
It really improves the development experience.
We built an open source remote MCP server that can automatically serve documentation from every Github project.
Simply replace github.com with gitmcp.io in the repo URL - and you get a remote MCP server that serves and searches the documentation from this repo (llms.txt, llms-full.txt, readme.md, etc). Works with github.io as well.
