I think it's a flaw in end-user MCP combined with agentic, where the end-user chooses the combination of tools. Even if the end-user is in an IDE.
The trouble is you can want an MCP server for one reason, flip it on, and a combination of the MCP servers you enabled and that you hadn't thought of suddenly breaks everything.
We need a much more robust deterministic non-LLM layer for joining together LLM capabilities across multiple systems. Or else we're expecting everyone who clicks a button in an MCP store to do extremely complex security reasoning.
Is giving an LLM running in an agentic loop every combination of even these vetted Microsoft MCP servers safe? https://code.visualstudio.com/mcp It seems unlikely.
