MOST DANGEROUS TOOLS

High Risk

The most dangerous A11y Agent tools

Execute · Medium run_keyboard_journey Executes keyboard interactions on web pages; effects depend on target page state and actions specified. Execute · Medium scan_page Triggers external browser execution against a URL to run accessibility audit. Execute · Medium verify_repair Triggers a browser rescan/execution against a page to verify accessibility fingerprints.

3 of A11y Agent's 6 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control A11y Agent

PolicyLayer is an MCP gateway — it sits between your AI agents and A11y Agent, and nothing reaches the server without passing your rules. These are the rules we recommend:

Cap read operations

{
  "compare_reports": {
    "limits": [
      {
        "counter": "compare_reports_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Create a free account and register A11y Agent — nothing to install.
Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on A11y Agent? +
