THE RISK

High Risk

Why crow_gis_create_geojson needs a policy

The tool executes a SQL query against a database to retrieve geospatial data and transform it into GeoJSON. The execution of arbitrary SQL queries poses significant risk — depending on the underlying database permissions, a malicious or erroneous query could access sensitive data, perform expensive operations, or (if write permissions exist) modify data.

From the tool's definition Generate GeoJSON from a SQL query result

How to control crow_gis_create_geojson

PolicyLayer is an MCP gateway — it sits between your AI agents and Crow, and nothing reaches the server without passing your rules. This is the rule we recommend for crow_gis_create_geojson:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "crow_gis_create_geojson": {
      "limits": [
        {
          "counter": "crow_gis_create_geojson_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

crow_gis_create_geojson stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Crow — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

What does the crow_gis_create_geojson tool do? +

Generate GeoJSON from a SQL query result that includes lat/lng columns. Returns a FeatureCollection for use in maps. It is categorised as a Execute tool in the Crow MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on crow_gis_create_geojson? +

Register the Crow MCP server in PolicyLayer and add a rule for crow_gis_create_geojson: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Crow. Nothing to install.

What risk level is crow_gis_create_geojson? +

crow_gis_create_geojson is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit crow_gis_create_geojson? +

Yes. Add a rate_limit block to the crow_gis_create_geojson rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block crow_gis_create_geojson completely? +

Set action: deny in the PolicyLayer policy for crow_gis_create_geojson. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides crow_gis_create_geojson? +

crow_gis_create_geojson is provided by the Crow MCP server (kh0pper/crow). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Crow tool call.

Start from Crow, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
