Why publish_featurestore needs a policy

Publishing a featurestore makes it accessible and registered in GeoServer, which is a reversible configuration change (can be unpublished). This is a Write operation rather than Execute because it creates/modifies metadata and configuration, not arbitrary code execution.

From the tool's definition Tool name 'publish_featurestore' and description 'Publish an existing featurestore' indicates creating or making visible a data store resource.

How to control publish_featurestore

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 publish_featurestore:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "publish_featurestore": {
      "limits": [
        {
          "counter": "publish_featurestore_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

publish_featurestore 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.

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