Experimenting with MCP servers to extend an agent — my honest take

Spent the last stretch wiring MCP servers into an agent product instead of hand-building every integration. The pitch is great in theory: paste a URL, click connect, tools show up as a checklist.

In practice it's been a mixed bag. Some servers are exactly as plug-and-play as advertised. Others expose tools that don't match how the underlying API actually behaves, so the agent confidently calls something that returns garbage, and you don't find out until you're debugging why a real user got a wrong answer.

Ended up hand-building the connectors that really matter (the ones where getting the semantics wrong costs someone money) and using MCP purely for the long tail where "mostly works" is good enough.

Anyone else gone deep on MCP servers? Curious if others found the same gap between the demo and production, or if I just hit unlucky servers.

how do you want to share a skill?

Whenever I search for a skill.MD file for a relevant skill there are tons of Github repositories that I find and none of them actually become useful to me because most of them have AI slop and actual hardcoded instruction which is necessary is somewhere buried in line 12 or 13 and the plug-in comes with a bunch of more files which I can swear I have never read.
What is the best way to share a skill that can be plugged to agentic workflows? And is anybody monetising this already?
With most of the skills that I find online, there is no true sense of ownership and most of them lack authenticity!!
