The rule that runs volcano.catalog.us safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Apibase, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For volcano.catalog.us, this is the rule to start with:
volcano.catalog.us is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Apibase, apply this rule, and every volcano.catalog.us call is checked against it from then on.
