Get SLD XML for classified vector style. Args: style_name (str): Name of style. column_name (str): Column to use for class. values (list): Scalar classes. color_ramp (str, optional): Colors. geom_type (str, optional): Geometry type. Returns: str: SLD XML.
AI agents call style_classified_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.
This tool retrieves and generates styling XML based on input parameters. It performs a read-only operation that queries geospatial style information and returns formatted output without creating, modifying, or deleting any data in the GeoServer. No side effects occur from calling this tool.
From the tool's definition Tool returns SLD XML for a classified vector style; the description states 'Get SLD XML' which indicates data retrieval with no side effects.
Documented attack patterns abuse exactly the kind of access style_classified_xml gives an agent:
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_classified_xml:
{
"version": "1",
"default": "deny",
"tools": {
"style_classified_xml": {}
}
}style_classified_xml is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get SLD XML for classified vector style. Args: style_name (str): Name of style. column_name (str): Column to use for class. values (list): Scalar classes. color_ramp (str, optional): Colors. geom_type (str, optional): Geometry type. Returns: str: SLD XML. It is categorised as a Read tool in the GeoServer MCP Server MCP Server, which means it retrieves data without modifying state.
Register the GeoServer MCP Server MCP server in PolicyLayer and add a rule for style_classified_xml: 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.
style_classified_xml 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 style_classified_xml 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 style_classified_xml. 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.
style_classified_xml 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.
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.
