Everything Wrong with MCP
The Model Context Protocol has security, UX, and LLM limitation issues that need formal standardization, particularly around access control and action criticality levels.
tl;dr
While MCP has rapidly become the de-facto standard for integrating third-party data and tools with LLMs, it has significant issues in protocol security, LLM security, UI/UX, and fundamental LLM limitations that need addressing before widespread adoption.
My Thoughts
There are some issues with MCPs that we need to make a formal standard on that protocol before adopting, eg: Protocol Security, LLM Security, UX/UI, limitations of LLMs. I think the main issue here is access control and how to determine for which agent what is the level of access / criticality of an action. Probably having a standard will be highly relevant here.
