Implement HTTP transport using SSE, Protocol 2024-11-05 (Final)

[Dogacel]

Description

Implement the HTTP transport using SSE. The CLI tool automatically determines whether the connection is an http or stdio by checking the command's arguments. If it is only 1 argument and starts with http:// or https://, it uses HTTP instead of stdio.

Hi Fatih, this project looks pretty cool, MCP is relatively new and I wanted to contribute. It's been a while since I have written Go so let me know if anything looks odd.

Also, I have implemented the solution based on "Final" edition. The "Latest" version actually changed quite a bit of things, it is much more complicated and I couldn't find any example project that used the new protocol (TBH I did not search hard enough).

Type of change

• New feature (non-breaking change which adds functionality)
• This change requires a documentation update

How Has This Been Tested?

I have run the "everything" MCP server using a docker image,

docker run -p 3001:3001 --rm -it tzolov/mcp-everything-server:v1

Later, I have conducted the test manually by calling the existing functionality,

Screen.Recording.2025-03-26.at.22.14.54.mov

Note that for some reason server exits when the connection is broken.

I belive there might be some kind of bug with tool calls in shell mode, I couldn't make it work.

Can you fix the lint errors?

Can you fix the lint errors?

I also found that lint makefile command was failing and tried to fix it by,

1. Fix makefile command
2. Add comment to transport package

Let me know if you want to add lint as a required step to setup as well. I expected it to run after running make but seems like it doesn't.
