Protocol version in the readme is Full MCP 2025-03-26 specification support

in the code it is "protocolVersion": "2024-11-05"

The fact that this is an achievement is a testament to how bloated the MCP protocol/spec already is.

Will be interesting to see how many days it'll take before the implementation no longer is the latest

It does not implement the Auth :)

(mcp auth is terrible btw)

This guide may be useful for anyone interested in building their own spec-compliant MCP server: https://simplescraper.io/blog/how-to-mcp.

Albeit, it's a few weeks old so already in need of an update!

Tool annotations are missing. (Are they of any use though?)

also checkout @profullstack/mcp-server on npm

What is MCP? I’ve never heard of it.

That README.md is so vibed with all the emojis and self-proofed comments. One day we’re going to look back on code written in June 2025 and laugh. The code works, but man does Claude 4 pump itself up.

Almost no client, including Claude Dekstop, implements Sampling.

I was so excited to see if I can create a server that used sampling and quickly figured out I can't use it anywhere. Funnily Windsurf hangs forever if you use sampling.
