WHAT IT DOES

What style_outline_only_xml does on GeoServer MCP Server

AI agents call style_outline_only_xml to retrieve information from GeoServer MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why style_outline_only_xml needs a policy

This tool constructs and returns an SLD XML document based on input parameters (color, width, geometry type). It has no side effects and does not interact with GeoServer's REST API to create or modify resources. It is purely a data-generation/query utility, making it a Read operation with low blast radius.

From the tool's definition Returns 'SLD XML for outline style' — the tool generates and returns an XML string; it does not persist, upload, or modify any server-side data.

POLICY

How to control style_outline_only_xml

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 style_outline_only_xml:

policy.json

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

style_outline_only_xml 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.
