RECOMMENDED RULE

The rule that runs nemu_list_symbols 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 nemu_list_symbols, this is the rule to start with:

nemu_list_symbols Allowed

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

  "tools": {
    "nemu_list_symbols": {}
  }
}

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

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