RECOMMENDED RULE

The rule that runs osv.security.get 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 osv.security.get, this is the rule to start with:

osv.security.get Allowed

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

  "tools": {
    "osv.security.get": {}
  }
}

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

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