1 of OneMap MCP Server's 50 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control OneMap MCP Server

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

Rate limit write operations

{
  "convert_4326_to_3857": {
    "limits": [
      {
        "counter": "convert_4326_to_3857_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "check_theme_status": {
    "limits": [
      {
        "counter": "check_theme_status_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

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