MCP access should not be all or nothing. A least-privilege router can allow read tools, ask for sensitive writes, and block risky actions.
Practical workflow
- Define team-level allow, ask, and block policy.
- Map tools to read, write, database, browser, and external-message risk tags.
- Require approval for higher-risk tool routes.
- Log every decision for audit review.
