CivilQuants MCP

Standards-aware civil-engineering quantity take-off — over MCP. Parametric inputs in; a deterministic, audit-traceable Bill of Quantities out, across four UK measurement standards (CESMM4, NRM2, SMM7, MMHW).

CivilQuants is a hosted remote MCP server; the engine source is proprietary. This repository is for discovery and connection docs — it contains no engine or application code.

What it is

CivilQuants is a deterministic, standards-aware quantification engine for civil engineering, accessible to any MCP-capable AI assistant. Give it the dimensions, materials and structure type for an assembly — box culvert, manhole, retaining wall, pavement, drainage run, earthworks — and it returns a structured Bill of Quantities aligned to your chosen UK measurement standard (CESMM4, NRM2, SMM7, MMHW), with a dimensioned drawing and every quantity traceable to its formula and inputs.

Six assemblies are available free and anonymously (rate-limited). A 7-day pass or subscription unlocks the full set of 46, plus Excel, DXF and PDF export and saved projects. Built by a working quantity surveyor; it supports your workflow and professional judgement rather than replacing them.

Connect

Remote endpoint	https://api.civilquants.com/mcp
Transport	Streamable HTTP
Free tier	Anonymous — no signup, rate-limited 10 calls/day per IP
Paid tier	OAuth 2.0 — full catalogue + clean Excel/DXF/PDF export + saved projects
Standards	CESMM4 · NRM2 · SMM7 · MMHW
Tools	50 — 46 compute_<assembly> + render_skill_report + save_project / get_project / recompute_project

The free tier needs no account: point an MCP-aware client at the endpoint and the tools appear. Full step-by-step setup for every client lives at civilquants.com/agent-docs.

Quick add

Most MCP clients take a remote server as a single URL. Where a client uses a JSON config, the entry is:

{
  "mcpServers": {
    "civilquants": {
      "url": "https://api.civilquants.com/mcp"
    }
  }
}

• Claude — add the URL as a custom connector (Claude Desktop one-click button on the agent docs).
• Cursor / Windsurf — add a server in MCP settings: name civilquants, URL https://api.civilquants.com/mcp.
• Gemini / ChatGPT / custom agents — connect to the Streamable HTTP endpoint via your MCP SDK; the free tier requires no auth.

See civilquants.com/agent-docs for the per-client walkthroughs, the full tool surface, and example prompts you can run.

Try it

Connect the server, then paste a prompt into your agent. These run on the free tier — no account needed:

Using CivilQuants, compute an MMHW Bill of Quantities for a precast concrete manhole 1.2 m diameter and 3 m deep.

Size an attenuation tank for a 0.5 ha car park and give me the bill of quantities.

Work out the cut and fill volumes for an embankment cross-section (give the chainage and cross-section areas) using the end-area method.

Scope

CivilQuants measures civil-engineering assemblies — it is not a complete project Bill of Quantities. Out of scope at v1: preliminaries, site clearance, demolition, project-scale bulk earthworks (only end-area along chainages is in scope), structures outside the catalogue, M&E, and project-level rates. Bring your prelims and site-wide quantities; CivilQuants produces the measured works.
