RISK

Why keychain_disconnect is rated Medium

This is classified as Write rather than Destructive because credential removal from a keychain is typically reversible—the user can re-authenticate and re-add credentials. It modifies the caller's own credential store (scoped to their UNCLICK_API_KEY) without permanently destroying underlying platform accounts.

From the tool's definition The tool description states it will 'Remove a platform credential from the UnClick Keychain,' which modifies stored authentication data by deleting/removing credentials.

RECOMMENDED RULE

The rule that runs keychain_disconnect safely

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

keychain_disconnect Rate-limited

keychain_disconnect 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.
