# compute_end_area_earthworks

Free tier. Renders the MMHW standard only — CESMM4, NRM2 and SMM7 require a paid tier. Anonymous callers welcome. Linear earthworks reach measured by the end-area method per MMHW Series 600 — Simpson's Rule with UK-QS even-ordinate trapezoidal-boundary fallback, with full SHW Series 600 Table 6/1 class tagging, mass-haul diagram (bulking + shrinkage per SHW Cl. 605), cut/fill balance, DISPOSAL vs FILL_GENERAL routing, capping and sub-base build-up, and topsoil strip + replacement. Renders identically across CESMM4 / NRM2 / MMHW / SMM7 with per-class line distinction. Example params: unacceptable_proportion=0 (0–1), topsoil_strip_depth_m=0.15 m (0–1), topsoil_replace_depth_mm=150 mm (0–500). Example call: {"params": {"unacceptable_proportion": 0, "topsoil_strip_depth_m": 0.15, "topsoil_replace_depth_mm": 150}, "standard": "MMHW"}. Omitted parameters use sensible engineering defaults. Pass deliverables=["xlsx","dxf","pdf"] (any subset) to also receive one-shot download URLs in the same call: Excel BoQ (both tiers, watermarked free) plus the dimensioned DXF (CAD) and PDF drawing sheets (paid tier).

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `params` | object | yes | Inputs for a linear earthworks reach measured by the end-area method. The five area streams in each `CrossSection` are integrated independently along the chain |
| `standard` | string | no |  |
| `output_mode` | string | no |  |
| `deliverables` | object | no |  |

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": "compute_end_area_earthworks",
    "arguments": {
      "params": {}
    }
  }
}
```

## Why compute_end_area_earthworks is rated High

While the tool does not modify persistent data or execute arbitrary code, it runs deterministic computational algorithms on provided parameters to generate engineering estimates and calculations. This fits Execute rather than Read because it performs transformative calculations whose outputs depend substantively on inputs and could influence real-world construction decisions.

From the tool's own definition: "Tool performs parametric estimating computations including 'Simpson's Rule', 'mass-haul diagram', 'cut/fill balance' calculations, and applies SHW/CESMM4 standards to earthworks data."

Risk signals: High parameter count (28 properties)

## Use case

AI agents invoke compute_end_area_earthworks to trigger actions in Civilquants. 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 Civilquants:

```json

  "version": "1",
  "default": "deny",
  "tools": {
    "compute_end_area_earthworks": {
      "limits": [
