I haven’t seen a single major MCP provider that would let us limit access properly
Miro, Linear, Notion etc… They just casually let the MCP do anything the user can and access everything.
For example: Legal is never letting us connect to Notion MCP as is because it has stuff that must NEVER reach any LLM even if they pinky swear not to train with our stuff.
-> thus, hard deterministic limits are non-negotiable.
it's straightforward to spin up a custom MCP wrapper around any API with whatever access controls you want
the only time i reach for official MCP is when they offer features that are not available via API - and this annoys me to no end (looking at you Figma, Hex)
