“Australian construction carbon accounting agent: search 4,300+ construction materials with embodied carbon factors, retrieve emission factors, and access NCC 2025 J9.4, AASB S2, EN 15978 lifecycle guidance. Exposed over MCP (streamable HTTP) and a REST API — this card describes those interfaces; no A2A task endpoint is offered.

Everything here is a check agenttru.st performed itself. Assurance, protocol, hosting and freshness are in the card above and are not repeated.

Certificate: Issued by Google Trust Services domain-validated
Valid until 6 Jan 2027 as of our check on 9 Nov 2026.

Control of the hostname was checked; nothing about who operates it.

Key ECDSA P-256, signed ECDSA-SHA256, issued via WE1 under GTS Root R4 — classical, as every publicly trusted certificate is today.

DANE / TLSA: Not verified
Discovery: Well-known document
This host also publishes an ARD catalog (/.well-known/ai-catalog.json) declaring 7 resources. The catalog's entries are the publisher's claims, not something agenttru.st verified.
AI use policy: Search: yesAI training: nouse: reference

What this site's robots.txt says about how AI may use its content. Recorded as the operator wrote it, not enforced — these are preferences about use, not access, and agenttru.st only reads the agent's own discovery documents.
AI-facing documents: Publishes /llms.txt — “CarbonConstruct™” a curated map of the site's content for language models

Publishes a Web Bot Auth key directory (1 key, EdDSA) — the operator publishes keys so their agent's signed requests can be verified. agenttru.st recorded that the directory exists; it has not verified a signature.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of www.carbonconstruct.com.au controls every word below.

Search construction materials

Search 4,300+ construction materials by name or category and return embodied carbon (GWP) factors with data-quality tiers and EPD provenance.

What its catalog declares

From the ARD catalog this host publishes at /.well-known/ai-catalog.json. The operator controls every entry; agenttru.st verified that the catalog exists and parses, and nothing about what the entries say.

CarbonConstruct MCP Server

mcp-server-card

Hosted Model Context Protocol server (streamable HTTP, JSON-RPC) exposing 14 tools: material and EPD search, carbon calculation, compliance validation, NEMF factor lookup, IFC parsing, project summaries and Autodesk model access. Requires a bearer token; see the server card.
