MOST DANGEROUS TOOLS

High Risk

The most dangerous MCP Server POC tools

Execute · Low calculate The tool executes computation logic rather than simply reading stored data. Write · High write_file This tool creates or modifies file content, which is reversible (files can be edited or deleted afterward).

2 of MCP Server POC's 5 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control MCP Server POC

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

Rate limit write operations

{
  "write_file": {
    "limits": [
      {
        "counter": "write_file_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "fetch_url": {
    "limits": [
      {
        "counter": "fetch_url_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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