WHAT IT DOES

What access_create_credential does on UniFi Access MCP

AI agents use access_create_credential to create or update resources in UniFi Access MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your UniFi Access MCP environment.

RISK

Why access_create_credential is rated Medium

This tool creates credentials (access passes/tokens) for the UniFi Access physical security system. This is a Write operation because it creates new data objects. Severity is high because miscreated credentials could grant unauthorized physical access to facilities, but the action is reversible (credentials can be deleted).

From the tool's definition Tool name 'access_create_credential' indicates creation of credentials in a physical access control system (UniFi Access). The server manages 'credentials' which are authentication tokens/passes for door access.

RECOMMENDED RULE

The rule that runs access_create_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_create_credential, this is the rule to start with:

access_create_credential Rate-limited

access_create_credential stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
