Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs proto_export_schema safely

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

proto_export_schema Rate-limited

proto_export_schema stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

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