The most dangerous Mcp Wag tools

3 of Mcp Wag's 7 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

How to control Mcp Wag

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

Block financial tools by default
{
  "book_walk": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Requires human approval."
      }
    ]
  }
}

Financial tools should be explicitly enabled per use case, not open by default.

Rate limit write operations
{
  "rate_walker": {
    "limits": [
      {
        "counter": "rate_walker_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations
{
  "get_pet_report": {
    "limits": [
      {
        "counter": "get_pet_report_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

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

Questions about Mcp Wag

Can an AI agent move money through the Mcp Wag MCP server? +

Yes. The Mcp Wag server exposes 2 financial tools including book_walk, schedule_recurring. Without a policy, an autonomous agent can call these with no spend caps, no rate limits, and no approval flow. PolicyLayer lets you block financial tools by default, require human approval, or set per-tool rate limits — enforced on every call.

How do I prevent bulk modifications through Mcp Wag? +

The Mcp Wag server has 1 write tools including rate_walker. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach Mcp Wag.

How many tools does the Mcp Wag MCP server expose? +

7 tools across 2 categories: Read, Write. 4 are read-only. 3 can modify, create, or delete data.

How do I enforce a policy on Mcp Wag? +

Register the Mcp Wag MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.
