What compute_end_area_earthworks does on Civilquants
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.
| 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 | — | |
output_mode | string | — | |
deliverables | object | — |
Parameters from the server's own tool schema.
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 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.

The rule that runs compute_end_area_earthworks safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Civilquants, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For compute_end_area_earthworks, this is the rule to start with:
compute_end_area_earthworks stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Civilquants, apply this rule, and every compute_end_area_earthworks call is checked against it from then on.
Questions about 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). It is categorised as a Execute tool in the Civilquants MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
compute_end_area_earthworks accepts 4 parameters: params, standard, output_mode, deliverables. Required: params. The full parameter table on this page comes from the server's own tool schema.
Register the Civilquants MCP server in PolicyLayer and add a rule for compute_end_area_earthworks: 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 Civilquants. Nothing to install.
compute_end_area_earthworks is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the compute_end_area_earthworks 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.
Set action: deny in the PolicyLayer policy for compute_end_area_earthworks. 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.
compute_end_area_earthworks is provided by the Civilquants MCP server (https://api.civilquants.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
