2 of Tanstack Start Devtools'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 Tanstack Start Devtools

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

Cap read operations

{
  "get_connection_status": {
    "limits": [
      {
        "counter": "get_connection_status_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

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.
