WHAT CAN GO WRONG

Write operations (convert_city_to_latitude_longitude) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.

RECOMMENDED RULES

Rate limit write operations

{
  "convert_city_to_latitude_longitude": {
    "limits": [
      {
        "counter": "convert_city_to_latitude_longitude_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "daily_air_quality_forecast": {
    "limits": [
      {
        "counter": "daily_air_quality_forecast_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

FAQ

How do I prevent bulk modifications through Measure Space? +

The Measure Space server has 1 write tools including convert_city_to_latitude_longitude. 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 Measure Space.

How many tools does the Measure Space MCP server expose? +

12 tools across 2 categories: Read, Write. 11 are read-only. 1 can modify, create, or delete data.

How do I enforce a policy on Measure Space? +

Register the Measure Space 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.

Enforce policy on every Measure Space tool call.

Deterministic rules across all 12 Measure Space tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
