MOST DANGEROUS TOOLS

High Risk

The most dangerous Software Design Mermaid tools

Execute · Medium show_diagram The tool triggers an external operation by opening a browser-based editor, which constitutes executing an action in an external environment. Write · Low close_diagram This tool performs a graceful session termination that may persist state (returns final code) and stops a service.

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

POLICY

How to control Software Design Mermaid

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

Rate limit write operations

{
  "close_diagram": {
    "limits": [
      {
        "counter": "close_diagram_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_diagram_feedback": {
    "limits": [
      {
        "counter": "get_diagram_feedback_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

FAQ

Questions about Software Design Mermaid

How do I prevent bulk modifications through Software Design Mermaid? +

The Software Design Mermaid server has 1 write tools including close_diagram. 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 Software Design Mermaid.

How many tools does the Software Design Mermaid MCP server expose? +

3 tools across 2 categories: Read, Write. 1 are read-only. 2 can modify, create, or delete data.

How do I enforce a policy on Software Design Mermaid? +

Register the Software Design Mermaid 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.
