The rule that runs list_surface_credentials safely
PolicyLayer is an MCP gateway: it sits between your AI agents and metagraphed — Bittensor subnet operational registry, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_surface_credentials, this is the rule to start with:
list_surface_credentials 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 metagraphed — Bittensor subnet operational registry, apply this rule, and every list_surface_credentials call is checked against it from then on.
