RECOMMENDED RULE

The rule that runs find_definition safely

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

find_definition Allowed

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

View as policy code

policy.json

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

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

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