What compute_attenuation_tank does on Civilquants
AI agents call compute_attenuation_tank 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_attenuation_tank is rated Low
This is a computational estimation tool that takes geometric parameters and returns a Bill of Quantities document. It reads/computes data based on inputs and renders output. There is no write, execute, destructive, or financial action involved — it is purely a calculation/query engine.
From the tool's definition 'Renders the MMHW standard only' and 'Computes/returns Bills of Quantities' — the tool performs parametric estimation calculations and returns structured output with no side effects, data modification, or external operations.

The rule that runs compute_attenuation_tank 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_attenuation_tank, this is the rule to start with:
compute_attenuation_tank 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_attenuation_tank call is checked against it from then on.
Questions about compute_attenuation_tank
Free tier. Renders the MMHW standard only — CESMM4, NRM2 and SMM7 require a paid tier. Anonymous callers welcome. Stormwater attenuation tank supporting two configurations: modular geocellular crates (high void ratio, compact footprint) or large-bore pipe arrays (1.5m+ ID concrete pipes in parallel runs). Excavation may be open-battered or vertical-sided with sheet pile support. Example params: tank_length=30 m (2–200), crate_width=6 m (1–20), crate_height=1.2 m (0.4–3.6). Example call: {"params": {"tank_length": 30, "crate_width": 6, "crate_height": 1.2}, "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_attenuation_tank 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_attenuation_tank: 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_attenuation_tank 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_attenuation_tank 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_attenuation_tank. 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_attenuation_tank 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.
