WHAT IT DOES

What access_revoke_credential does on UniFi Access MCP

AI agents call access_revoke_credential to permanently remove resources in UniFi Access MCP, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why access_revoke_credential is rated Critical

Revoking a credential removes access rights, which is typically an irreversible or hard-to-undo action. In physical access control systems, revoking a credential can immediately lock someone out of secured areas. The description is empty, so confidence is reduced, but 'revoke' strongly implies a destructive, non-recoverable operation distinct from a soft 'disable'.

From the tool's definition Tool name 'access_revoke_credential' — 'revoke' implies permanently invalidating a credential, which is typically irreversible. Sibling tool 'access_create_credential' exists, suggesting revoke is the destructive counterpart.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs access_revoke_credential safely

PolicyLayer is an MCP gateway: it sits between your AI agents and UniFi Access MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For access_revoke_credential, this is the rule to start with:

access_revoke_credential Hidden

access_revoke_credential is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
