# CivilQuants — AI Connector CivilQuants publishes 53 MCP tools to Claude. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/productivity/civilquants/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Productivity](https://node8.ai/ai-connectors/productivity/) # CivilQuants Civil engineering take-off to CESMM4, NRM2, SMM7 and MMHW Listed in Claude · 53 published tools · Community-listed [Claude connector docs](https://civilquants.com/agent-docs) [civilquants.com](https://civilquants.com) Overview ## What CivilQuants does CivilQuants turns parametric inputs into audit-traceable bills of quantities for civil engineering assemblies, covering culverts, manholes, retaining walls, pavements, drainage and earthworks across four UK measurement standards: CESMM4, NRM2, SMM7 and MMHW. Traceability is the claim that matters in this work, since every quantity traces back to the formula that produced it, which is what makes a take-off defensible. Output exports to Excel, DXF and PDF. Beyond the calculators, paid subscribers get ten senior quantity surveyor methodology prompts covering tender review, risk assessment and geotechnical interpretation, run against their own documents. Six assemblies are free. ### Who it is for Quantity surveyors producing bills of quantities for civil engineering works. ### Tool surface Fifty-six tools answered against fifty-three claimed, and they are almost all calculators: compute\_manhole, compute\_box\_culvert, compute\_pipe\_bedding and compute\_french\_drain among them, one per assembly type. Availability ## Where CivilQuants is listed CivilQuants is listed in the Claude connectors directory only. Ember Forge Pte Ltd has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them. The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one. Claude listing ## In the Claude connectors directory CivilQuants publishes 53 tools to Claude, a deeper surface than 91.5% of the 1,253 Claude-listed connectors, the top decile. The median Claude-listed connector filed under Productivity publishes 12, so this one runs 41 tools above its bucket's median and ranks 39th of 462 by tool count. It falls in the 51+ tools band, which holds 9.6% of the Claude directory. ### Measured against the live endpoint A direct call to the endpoint returned 56 tools, 3 more than the 53 the listing publishes.

Claude connects to it over HTTP; there is nothing to install locally. Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there. Publisher Ember Forge Pte Ltd Verification Community-listed (61.5% of the Claude directory) Filed under Productivity Endpoint `https://api.civilquants.com/mcp` Documentation [Publisher setup docs](https://civilquants.com/agent-docs) Published tools 53 · 51+ tools band Depth rank in Productivity 39 of 462 Snapshot August 2026 CivilQuants is community-listed in the Claude directory, the tier 770 of 1,253 connectors sit in (61.5%). It is the default for a self-published server, and says nothing either way about quality. In the publisher's words ## How Ember Forge Pte Ltd describes it > CivilQuants turns parametric inputs into audit-traceable Bills of Quantities for civil engineering assemblies — culverts, manholes, retaining walls, pavements, drainage, earthworks — across four UK measurement standards (CESMM4, NRM2, SMM7, MMHW). Every quantity traces back to its formula, and you can export to Excel, DXF and PDF. Beyond the 46 calculators, paid subscribers get ten senior-QS methodology prompts — tender review, risk assessment, measurement and contract advice, geotechnical interpretation and more — run against your own documents. Six assemblies are free; built by a working quantity surveyor. Quoted from the connector's own Claude directory listing as captured in August 2026. Node8 did not write it and does not vouch for it.
