# Approve a proposed capability execution plan

`POST /v1/capability-executions/{plan_id}/approve`

  - HTTP bearer

Approval is an explicit, credentialed operation bound to the exact plan hash and a single-use nonce. It is intentionally not exposed as an MCP/LLM tool. Approving does NOT execute the capability (approve != execute) -- call POST /v1/capabilities/execute again with plan_id set to run it.
