Quantity Takeoff tools (7)

write = sends, deletes, buys or posts
  • calculate_takeoffFree

    Calculate an auditable material takeoff from explicit geometry or a supported SmartScale/ProtoGen measurement payload. Returns net, explicit waste-adjusted, and conservative purchase quantities. This is a planning estimate, not a guaranteed material order or professional certification.

  • describe_agentFree

    Return fleet-standard capabilities, version, pack digest, disclaimer, composition role, and pricing.

  • get_assemblyFree

    Return one assembly's formula, required dimensions, material factors, purchase increment, sources, and material-pack lineage.

  • get_material_packFree

    Return the bundled factors, densities, coverages, waste defaults, purchase increments, unit conversions, sources, and raw-pack SHA.

  • list_assembliesFree

    List supported assemblies, required dimensions, formulas, waste defaults, and the current material-pack digest.

  • list_material_packFree

    List the bundled material pack version, digest, coverage, shapes, rebar sizes, roof pitches, and explicit unsupported policy.

  • verify_resultFree

    Recompute a takeoff audit hash, notary payload, pack currency, and QT9 unit-resolved conservation. Pass the prior result object as JSON.

What the publisher says

From the Quantity Takeoff repository's README, as published. We do not edit it. Read it on GitHub

Viridis Agent Fleet: open-source agents for the agent economy

Deterministic, auditable MCP agents: trust and settlement rails (identity, trust, escrow, metering, arbitration, notary, surety, provenance, covenant, offsets, compute-ledger) and priced-grade services (tax credits, GHG accounting, construction takeoff, measurement, compliance). Every core is pure Python with no LLM in the serving path, and every result is content-addressed so anyone can re-verify it.

Licensed Apache-2.0. Run any agent yourself, fork it, embed it.

Run an agent locally (free, forever)

pip install -r requirements-dev.txt
python3 agent-escrow-agent/adapters/mcp_server.py          # stdio MCP
python3 run_fleet_tests.py                                 # every agent's invariant tests

Or use the hosted fleet

https://mcp.viridisconservation.com runs all agents as one managed MCP service:

Free tier: 10 calls/day per service; the rails (identity, escrow, metering…) are free forever. Verification is always free.

Boundary

This repo contains agent cores, MCP adapters, tests, standards and self-host tooling. The hosted service layer (gateway, payment and settlement, seats, signing authority, operations, telemetry and customer data) is proprietary and is not in this repo. Please don't open PRs that add it.
