THE RISK

Why getis_ord_g_local needs a policy

This is a read-only analytical tool that computes spatial statistics from geospatial data. It retrieves and processes GIS data to generate statistical measures of local spatial clustering, with no side effects, data modification, or irreversible actions. The 'local' variant indicates point-wise or localized analysis rather than global aggregation, but remains a query/analysis operation.

From the tool's definition Tool name 'getis_ord_g_local' and description 'Local Getis-Ord G' indicate a geospatial statistical analysis operation. Getis-Ord G is a spatial autocorrelation statistic that analyzes and quantifies clustering patterns in geographic data.

POLICY

How to control getis_ord_g_local

PolicyLayer is an MCP gateway — it sits between your AI agents and GIS MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for getis_ord_g_local:

policy.json

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

getis_ord_g_local 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 GIS 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.

FAQ

Questions about getis_ord_g_local

What does the getis_ord_g_local tool do? +

Local Getis-Ord G. It is categorised as a Read tool in the GIS MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on getis_ord_g_local? +

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

What risk level is getis_ord_g_local? +

getis_ord_g_local is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit getis_ord_g_local? +

Yes. Add a rate_limit block to the getis_ord_g_local 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 getis_ord_g_local completely? +

Set action: deny in the PolicyLayer policy for getis_ord_g_local. 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 getis_ord_g_local? +

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

Enforce policy on every GIS MCP Server tool call.

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