THE RISK

Low Risk

Why get_layer_info needs a policy

This tool queries and retrieves layer metadata from GeoServer. It takes workspace and layer name as arguments and returns information—a read operation with no capability to modify, delete, or execute actions. No side effects are described or implied. Severity is low because geospatial metadata disclosure poses minimal risk compared to data modification or deletion tools present on the same server.

From the tool's definition Tool name 'get_layer_info' and description 'Get detailed information about a layer' with 'Returns: Dict with layer metadata' indicates retrieval of data without side effects.

POLICY

How to control get_layer_info

PolicyLayer is an MCP gateway — it sits between your AI agents and GeoServer MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_layer_info:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_layer_info": {}
  }
}

get_layer_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register GeoServer MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
