WHAT IT DOES

What crow_gis_create_geojson does on Crow

AI agents invoke crow_gis_create_geojson to trigger actions in Crow. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why crow_gis_create_geojson is rated High

This tool executes a SQL query against a database to retrieve geospatial data and transform it into GeoJSON. The execution of arbitrary SQL queries represents an Execute-level risk, as the query contents determine the actual operations performed. Depending on the SQL permitted, this could range from simple reads to destructive operations.

RECOMMENDED RULE

The rule that runs crow_gis_create_geojson safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Crow, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For crow_gis_create_geojson, this is the rule to start with:

crow_gis_create_geojson Rate-limited

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.
