WHAT IT DOES

What create_gpkg_datastore does on GeoServer MCP Server

AI agents use create_gpkg_datastore to create or update resources in GeoServer MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your GeoServer MCP Server environment.

THE RISK

Medium Risk

Why create_gpkg_datastore needs a policy

This tool creates a new datastore configuration in GeoServer, which is a reversible write operation. It does not execute arbitrary code, delete data, or move money. However, it modifies system state by adding new geospatial data sources, which could affect downstream queries and analyses.

From the tool's definition Tool name contains 'create' and description explicitly states 'Create a GeoPackage (GPKG) datastore.' The function creates new data storage resources in GeoServer.

POLICY

How to control create_gpkg_datastore

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 create_gpkg_datastore:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_gpkg_datastore": {
      "limits": [
        {
          "counter": "create_gpkg_datastore_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_gpkg_datastore 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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about create_gpkg_datastore

What does the create_gpkg_datastore tool do? +

Create a GeoPackage (GPKG) datastore. Args: workspace (str): Workspace name. name (str): Datastore name. file_path (str): Path to the .gpkg file (relative to --storage if provided) Returns: dict: Creation result. It is categorised as a Write tool in the GeoServer MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_gpkg_datastore? +

Register the GeoServer MCP Server MCP server in PolicyLayer and add a rule for create_gpkg_datastore: 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 GeoServer MCP Server. Nothing to install.

What risk level is create_gpkg_datastore? +

create_gpkg_datastore is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_gpkg_datastore? +

Yes. Add a rate_limit block to the create_gpkg_datastore 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.

How do I block create_gpkg_datastore completely? +

Set action: deny in the PolicyLayer policy for create_gpkg_datastore. 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.

What MCP server provides create_gpkg_datastore? +

create_gpkg_datastore is provided by the GeoServer MCP Server MCP server (mahdin75/geoserver-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every GeoServer MCP Server tool call.

Start from GeoServer MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
