RECOMMENDED RULE

The rule that runs list_instance_mcp_grants safely

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

list_instance_mcp_grants Allowed

list_instance_mcp_grants is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_instance_mcp_grants": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect ProAgentStore, apply this rule, and every list_instance_mcp_grants call is checked against it from then on.
