AI agents invoke transform-coordinates to trigger actions in PostGIS MCP Server. 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.
This tool executes a coordinate system transformation operation, which is a computational operation with side effects on data representation. While not destructive or financial, it modifies how spatial data is interpreted and used downstream. The transformation could affect analysis results if applied incorrectly, making it Execute category rather than simple Read.
From the tool's definition Tool name 'transform-coordinates' and description 'Koordinat sistemini dönüştür' (Turkish: 'Transform coordinate system') indicates execution of a spatial transformation operation that affects coordinate reference system conversion.
Documented attack patterns abuse exactly the kind of access transform-coordinates 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 transform-coordinates:
{
"version": "1",
"default": "deny",
"tools": {
"transform-coordinates": {
"limits": [
{
"counter": "transform-coordinates_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}transform-coordinates 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.
Free to start. No card required.
Koordinat sistemini dönüştür. It is categorised as a Execute tool in the PostGIS MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the PostGIS MCP Server MCP server in PolicyLayer and add a rule for transform-coordinates: 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.
transform-coordinates is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the transform-coordinates 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 transform-coordinates. 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.
transform-coordinates 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.
