WHAT IT DOES

What revoke_kb_access does on FlowDot MCP Server

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

RISK

Why revoke_kb_access is rated Critical

Revoking access is an irreversible action that removes permissions/grants. Once a grant is revoked, the access is gone and must be re-granted explicitly. This is a destructive operation on access control with high blast radius if misused, as it could lock out users or systems from knowledge bases they depend on.

RECOMMENDED RULE

The rule that runs revoke_kb_access safely

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

revoke_kb_access Hidden

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