AI agents call raster_info to retrieve information from Gdal without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'info' suffix strongly implies a read-only metadata retrieval operation, consistent with GDAL's gdalinfo utility which inspects raster file properties. The sibling 'vector_info' tool reinforces this pattern. No description is provided, which lowers confidence slightly, but the naming convention is clear. Misuse potential is low as it only reads file metadata.
From the tool's definition Tool name 'raster_info' alongside sibling tools like 'raster_query' and 'vector_info' suggests this retrieves metadata/information about raster files without side effects.
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 Gdal, 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_info. It is categorised as a Read tool in the Gdal MCP Server, which means it retrieves data without modifying state.
Register the Gdal 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 Gdal. 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 Gdal MCP server (jordangunn/gdal-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
