## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "geomech_fault_stability",
    "arguments": {}
  }
}
```

## Why geomech_fault_stability is rated High

Based on the server context (petroleum engineering calculations) and tool name, this tool likely performs geomechanical fault stability analysis calculations. In the context of sibling tools that perform calculations (arps_rate, arps_cumulative, etc.), this is most likely a computational/analytical tool (Execute or Read). With no description available, confidence is low.

From the tool's own definition: "Tool name 'geomech_fault_stability' suggests geomechanical fault stability calculation, but description is empty and uninformative."

## Use case

AI agents invoke geomech_fault_stability to trigger actions in pyResToolbox MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches pyResToolbox MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "geomech_fault_stability": {
      "limits": [
        {
          "counter": "geomech_fault_stability_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
