Parameters from the server's own tool schema.

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "paver",
    "arguments": {
      "shape": "<shape>",
      "base_depth_in": 0
    }
  }
}
```

## Why paver is rated Low

This tool performs mathematical calculations on user-provided inputs (patio dimensions, cutout specifications) and returns estimated results (paver count, material quantities, cost estimates). It retrieves/computes data without persisting state changes, modifying external systems, or executing side effects.

From the tool's own definition: "Tool name 'paver' and description 'Paver Calculator — Paver count, base material and cost for a patio/walkway, including cutouts and waste.' indicates a calculation/estimation tool that computes quantities and costs based on input dimensions."

Risk signals: High parameter count (15 properties)

## Use case

AI agents call paver to retrieve information from Gateway without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Gateway:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "paver": {}
  }
}
```
