Full written post / accessibility read
I open the tools plane docs and look for cancel job, continue from prior response, and collect artifacts. Those verbs belong to a job contract. If they are missing, MCP is doing its real job as tools and data, not as the whole stack.
Next I ask where allow and deny are decided. Host, gateway, policy. If someone points only at the MCP schema, the enforcement story is incomplete. That is the field test for a tools plane claim.
I keep a sticky that says untested on any sentence that claims MCP alone solves permissions. Evidence boundaries matter when security is asked to sign.
Write one paragraph in the architecture doc: MCP is tools and data; enforcement is host side; job lifecycle is elsewhere. That short note saves a long false review later.

Four-beat scene transcript
1. Ask MCP to cancel a job.
I open the tools plane docs and look for cancel job, continue from prior response, and collect artifacts. Those verbs belong to a job contract. If they are missing, MCP is doing its real job as tools and data, not as the whole stack.
Visual: If the answer is silence, you found the boundary.
2. Then ask who enforces.
Next I ask where allow and deny are decided. Host, gateway, policy. If someone points only at the MCP schema, the enforcement story is incomplete. That is the field test for a tools plane claim.
Visual: Schema is not the allow list.
3. Label synthesis honestly.
I keep a sticky that says untested on any sentence that claims MCP alone solves permissions. Evidence boundaries matter when security is asked to sign.
Visual: MCP solves permissions is untested.
4. Ship the boundary note.
Write one paragraph in the architecture doc: MCP is tools and data; enforcement is host side; job lifecycle is elsewhere. That short note saves a long false review later.
Visual: Tools plane, named and limited.
