RECOMMENDED RULE

The rule that runs scan_dir safely

PolicyLayer is an MCP gateway: it sits between your AI agents and A11ychk, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For scan_dir, this is the rule to start with:

scan_dir Allowed

scan_dir 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": {
    "scan_dir": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect A11ychk, apply this rule, and every scan_dir call is checked against it from then on.
