Authz Check
Verify that an endpoint checks ownership, not just authentication. Use on any handler that reads or mutates user data.

Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Authz Check
The most common security hole: the code checks you're logged IN, but not that you OWN the thing.
- For every resource access: does it verify the current user is allowed THIS specific record?
WHERE id = ? AND owner_id = current_user— not justWHERE id = ?. - IDOR test: swap the ID in the request to another user's. Does it leak/allow?
- Admin/privileged actions: is the role checked server-side, every time, not just hidden in the UI?
- Default deny: new endpoints should require explicit authorization, not be open by oversight.
Output each handler that authenticates but doesn't authorize, with the missing check.
