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

Why compute_french_drain is rated Low
This tool is a parametric quantity/cost estimation engine that computes Bills of Quantities outputs for a french drain assembly. It reads input parameters and renders structured estimating data across standard measurement frameworks. No data is written, deleted, or executed — it is a calculation/reporting tool.
From the tool's definition Parametric estimating engine... Renders cleanly across CESMM4 / NRM2 / MMHW... Composes the bedding primitive... with three additions: perforated carrier, filter geotextile wrap, and optional top seal

Attacks that exploit this kind of access
The rule that runs compute_french_drain 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_french_drain, this is the rule to start with:
compute_french_drain is read-only, so it stays allowed. 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_french_drain call is checked against it from then on.
Questions about compute_french_drain
Paid tier only. Calling this without an authenticated CivilQuants account returns TIER_INSUFFICIENT — sign up at https://civilquants.com/pricing or use the free-tier alternative compute_manhole. Perforated land drain in a granular-filled trench with non-woven filter geotextile wrap. Composes the bedding primitive at Class S geometry (full granular envelope) with three additions: perforated carrier, filter geotextile wrap, and optional top seal. Renders cleanly across CESMM4 / NRM2 / MMHW (Series 500 filter drain) and SMM7. Example params: pipe_internal_diameter_mm=150 mm (80–600), pipe_wall_thickness_mm=25 mm (5–80), drain_length=50 m (1–500). Example call: {"params": {"pipe_internal_diameter_mm": 150, "pipe_wall_thickness_mm": 25, "drain_length": 50}, "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 Read tool in the Civilquants MCP Server, which means it retrieves data without modifying state.
compute_french_drain 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_french_drain: 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_french_drain is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the compute_french_drain 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_french_drain. 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_french_drain 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.
