## Facts

- Tool: `beta_to_lorenz`
- Server: pyResToolbox MCP Server (`gabrielserrao/pyrestoolbox-mcp`) — https://policylayer.com/tools/gabrielserrao-pyrestoolbox-mcp.md
- Homepage: https://github.com/gabrielserrao/pyrestoolbox-mcp
- Risk category: Other (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

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

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

## Why beta_to_lorenz is rated Low

The tool name suggests a mathematical/statistical conversion (Beta distribution to Lorenz coefficient, commonly used in reservoir heterogeneity characterization). Based on server context (petroleum engineering calculations) and sibling tools (PVT, decline curves, reservoir simulation), this is likely a read/compute operation with no side effects. Empty description lowers confidence significantly.

From the tool's own definition: "Tool name 'beta_to_lorenz' with empty description. No description provided to clarify behavior."

## Use case

AI agents call beta_to_lorenz as a supporting operation in pyResToolbox MCP Server workflows.

## 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": {
    "beta_to_lorenz": {
      "limits": [
        {
          "counter": "beta_to_lorenz_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
