I could see some cases were the tools are user data specific. You upload some csv and now there are some tools customized for slicing and manipulating that data.
It's totally possible to build tools in way that everything is static but might be less intuitive for some use cases.
Totally agree, hopefully it's clear closer to the end that I don't actually expect MCP to solve and be responsible for a lot of this. More so MCP creates a lot of surface area for these issues that app developers and users should be aware of.
