Everything to evaluate and integrate.
The assembly catalogue, how the engine is built, agent and API integration, and the free MCP tier. Parameter references and the output schema for each assembly live in-context — in the workspace form and the agent resources.
§ 01 · Where to look
Assembly catalogue
All 46 parametric assemblies across six civils families — six free to evaluate, forty paid. Each opens a workspace with its parameter form, live drawing, and per-standard bill.
Browse the catalogue →How the engine works
Single-file parametric assemblies, one calculation kernel, four measurement methodologies (CESMM4, NRM 2, SMM7, MMHW). Deterministic outputs with an audit trail under every row, and the architectural invariants that keep them honest.
Read the engine notes →Agent & API integration
Connect via MCP, REST, the Python stub client, or the CLI — all one FastAPI service. Tool list, resource list, request/response shapes, rate limits, and the parameter + output schema for agents.
Open agent docs →Free MCP tier
Add the engine to your LLM client and evaluate six assemblies plus two site tools before buying. One-click for Claude Desktop, manual endpoint for other clients. No signup, 10 calls a day per IP.
Set up the free tier →Free site tools
Plant productivity and aggregate conversion calculators — free utilities that sit alongside the parametric engine.

What each tier unlocks: the full catalogue, watermark-free PDF + Excel + DXF, and the project workspace. Rates are always supplied by you.
