MOST DANGEROUS TOOLS

High Risk

The most dangerous MCP Demo Application tools

Execute · Medium calculate This tool evaluates mathematical expressions, which constitutes executing computation. Write · Low store_note This tool writes a note to the system, which is a reversible write operation. Write · Medium generate_uuid Generate a random UUID (Universally Unique Identifier).

3 of MCP Demo Application'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 Demo Application

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

Rate limit write operations

{
  "generate_uuid": {
    "limits": [
      {
        "counter": "generate_uuid_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_weather": {
    "limits": [
      {
        "counter": "get_weather_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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