AI agents call raster-info to retrieve information from PostGIS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries information about raster data in the PostGIS database. It has no side effects and does not create, modify, delete, or execute operations. The action is purely informational/read-only, consistent with the Read category for data retrieval tools. The low severity reflects minimal risk if misused, as it only exposes metadata.
From the tool's definition Tool name 'raster-info' and description 'Raster verisinin bilgilerini al' (Turkish: 'Get raster data information') indicate retrieval of metadata or information about raster data without modification.
Documented attack patterns abuse exactly the kind of access raster-info 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 raster-info:
{
"version": "1",
"default": "deny",
"tools": {
"raster-info": {}
}
}raster-info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Raster verisinin bilgilerini al. It is categorised as a Read tool in the PostGIS MCP Server MCP Server, which means it retrieves data without modifying state.
Register the PostGIS MCP Server MCP server in PolicyLayer and add a rule for raster-info: 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.
raster-info is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the raster-info 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 raster-info. 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.
raster-info 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.
