What compute_pipe_bedding does on Civilquants
AI agents invoke compute_pipe_bedding 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.

Parameters from the server's own tool schema.
Why compute_pipe_bedding is rated High
While the tool does not modify persistent data or delete anything, it executes complex estimating logic with configurable parameters that produce deterministic but non-trivial outputs (bills of quantities, trench specifications, cost implications). The output affects downstream civil engineering decisions and financial planning. It requires authentication and is paid-tier only, indicating material business logic.
From the tool's definition Tool 'compute_pipe_bedding' performs parametric estimation calculations ('Emits trench excavation, granular bed, surround or concrete cradle/encasement, selected backfill, disposal and pipework').

The rule that runs compute_pipe_bedding 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_pipe_bedding, this is the rule to start with:
compute_pipe_bedding 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_pipe_bedding call is checked against it from then on.
Questions about compute_pipe_bedding
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. Linear pipe trench with class-driven bedding and surround. Strategy pattern on (BeddingContext × BeddingClass): Highway (HA 40/01 / MMHW Series 500) vs Building (BS EN 1610 / NRM2 §33), Class N/F/B/S/A/Z. Emits trench excavation, granular bed, surround or concrete cradle/encasement, selected backfill, disposal and pipework. All four standards render with class and clause references. Example params: pipe_internal_diameter_mm=300 mm (100–1800), pipe_wall_thickness_mm=50 mm (10–200), pipe_length=25 m (1–500). Example call: {"params": {"pipe_internal_diameter_mm": 300, "pipe_wall_thickness_mm": 50, "pipe_length": 25}, "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_pipe_bedding 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_pipe_bedding: 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_pipe_bedding 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_pipe_bedding 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_pipe_bedding. 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_pipe_bedding 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.
