AI agents use create-point 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 new spatial data objects (points) in the PostGIS database. This is a Write operation as it generates new data that modifies the database state reversibly. Severity is medium because while geometry creation is reversible (points can be deleted), in a spatial database context, bulk or maliciously-placed geometries could impact query performance or clutter the database.
From the tool's definition Tool name 'create-point' and description indicate creation of point geometry objects in PostGIS database. Description translates from Turkish as 'Create point geometry from coordinates,' which is explicitly a creation operation.
Documented attack patterns abuse exactly the kind of access create-point 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-point:
{
"version": "1",
"default": "deny",
"tools": {
"create-point": {
"limits": [
{
"counter": "create-point_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create-point 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.

Koordinatlardan nokta 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-point: 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-point 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-point 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-point. 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-point 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.
