THE RISK

Low Risk

Why morans_i needs a policy

Moran's I is a purely analytical/computational operation that reads geospatial data to derive a statistical measure of spatial autocorrelation. It does not create, modify, or delete data; does not execute arbitrary code or shell commands; and does not involve financial transactions. The tool fits the Read category as it retrieves and analyzes data with no side effects on the underlying datasets.

From the tool's definition Tool name 'morans_i' and description 'Compute Moran's I Global Autocorrelation Statistic' indicate a statistical computation that reads and analyzes existing geospatial data without modifying, deleting, or executing external operations.

POLICY

How to control morans_i

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 morans_i:

policy.json

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

morans_i 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 morans_i

What does the morans_i tool do? +

Compute Moran's I Global Autocorrelation Statistic. 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 morans_i? +

Register the GIS MCP Server MCP server in PolicyLayer and add a rule for morans_i: 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 morans_i? +

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

Can I rate-limit morans_i? +

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

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

morans_i 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.
