The most dangerous Mc tools

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

How to control Mc

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

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

Prevents bulk unintended modifications from agents caught in loops.

  1. Create a free account and register Mc — 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 Mc

How do I prevent bulk modifications through Mc? +

The Mc server has 1 write tools including send_message. 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 Mc.

How many tools does the Mc MCP server expose? +

3 tools across 2 categories: Execute, Write. 0 are read-only. 3 can modify, create, or delete data.

How do I enforce a policy on Mc? +

Register the Mc 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.
