Generate color map entries for raster SLD. Args: color_ramp: List/dict of colors. min_value (float): Minimum value. max_value (float): Maximum value. number_of_classes (int, optional): Number of classes. Returns: List or dict: Colormap structure for SLD.
AI agents call style_coverage_style_colormapentry as a supporting operation in GeoServer MCP Server workflows.
This tool purely generates/computes a data structure (colormap entries) for use in SLD styling. It does not read from, write to, or modify any external system — it is a local computation that returns a structured result. No network calls, no data persistence, no side effects implied.
From the tool's definition Generate color map entries for raster SLD... Returns: List or dict: Colormap structure for SLD.
Documented attack patterns abuse exactly the kind of access style_coverage_style_colormapentry 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_coverage_style_colormapentry:
{
"version": "1",
"default": "deny",
"tools": {
"style_coverage_style_colormapentry": {
"limits": [
{
"counter": "style_coverage_style_colormapentry_rate",
"window": "minute",
"max": 60,
"scope": "grant"
}
]
}
}
} style_coverage_style_colormapentry gets a rate cap, and everything else on the server is denied unless you say otherwise.

Generate color map entries for raster SLD. Args: color_ramp: List/dict of colors. min_value (float): Minimum value. max_value (float): Maximum value. number_of_classes (int, optional): Number of classes. Returns: List or dict: Colormap structure for SLD. It is categorised as a Other tool in the GeoServer MCP Server MCP Server, which means it performs auxiliary operations.
Register the GeoServer MCP Server MCP server in PolicyLayer and add a rule for style_coverage_style_colormapentry: 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_coverage_style_colormapentry is a Other tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the style_coverage_style_colormapentry 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_coverage_style_colormapentry. 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_coverage_style_colormapentry 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.
