Koordinat dizisinden poligon geometrisi oluştur
AI agents use create-polygon to create or update resources in PostGIS MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your PostGIS MCP Server environment.
This tool creates spatial geometry data structures (polygons) which is a reversible write operation. It does not execute arbitrary code or delete data, making it Write rather than Execute or Destructive. The severity is medium because while polygon creation is generally safe, misuse could create invalid geometries, corrupt spatial indices, or generate large numbers of objects consuming resources. The confidence is 0.
From the tool's definition Tool name 'create-polygon' and description 'Koordinat dizisinden poligon geometrisi oluştur' (Create polygon geometry from coordinate array) indicate the tool creates/constructs a new geometric object in the PostGIS database.
Documented attack patterns abuse exactly the kind of access create-polygon gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and PostGIS MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create-polygon:
{
"version": "1",
"default": "deny",
"tools": {
"create-polygon": {
"limits": [
{
"counter": "create-polygon_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create-polygon stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Koordinat dizisinden poligon geometrisi oluştur. It is categorised as a Write tool in the PostGIS MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the PostGIS MCP Server MCP server in PolicyLayer and add a rule for create-polygon: 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 PostGIS MCP Server. Nothing to install.
create-polygon is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create-polygon 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.
Set action: deny in the PolicyLayer policy for create-polygon. 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.
create-polygon is provided by the PostGIS MCP Server MCP server (receptopalak/postgis-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from PostGIS MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
