What unifi_unblock_client does on UniFi Access MCP
AI agents use unifi_unblock_client 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.
Why unifi_unblock_client is rated Medium
This tool reverses a block state on a network client/device, which is a reversible write/modify operation (toggling access control state). It does not delete data, execute arbitrary code, or involve financial transactions. Misuse could allow unauthorized devices back onto the network, hence medium severity.

The rule that runs unifi_unblock_client 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 unifi_unblock_client, this is the rule to start with:
unifi_unblock_client 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.
The button opens the PolicyLayer dashboard: create your workspace, connect UniFi Access MCP, apply this rule, and every unifi_unblock_client call is checked against it from then on.
