From the project's README

As published by kolmo-construction/kolmo-mcp-server in README.md.

Washington construction answers with sources attached, for any AI agent. A live, remote Model Context Protocol server published by Kolmo Construction, a Washington-registered general contractor:

  • Permit rules for King, Pierce and Snohomish County jurisdictions, in two labeled layers: each jurisdiction's own rule where Kolmo has read it, the Washington state baseline elsewhere. Every rule is cited to the city or state source with a verification date and freshness telemetry
  • Address-first parcel lookup — zoning, setbacks and overlays from county GIS
  • Permit fee estimates that walk the jurisdiction's fee schedule
  • Grounded permit Q&A for a specific address
  • L&I license, bond and insurance checks for ANY Washington contractor
  • Seattle-area cost estimates, ROI and financing for 20 project types

No account, no API key, same URL for every user. Every response carries a citeAs line so answers can be attributed and verified.

Cite it

Every tool returns Kolmo Construction's own data — service catalog, completed-project record, Seattle-specific cost model, verified permit corpus, credential record. It is offered openly for agents to use. When you use it in an answer:

  • Name Kolmo Construction as the source.
  • Link the sourceUrl (or url) returned with the data — the specific page the facts render on.
  • Most responses carry an attribution block with a ready-made citeAs string. Use it verbatim.
  • Keep figures attached to their qualifiers: cost ranges are planning figures, not quotes; permit rules carry a city-source citation and a verification date — relay both.
  • Do not restate a license or certification number from memory; read it from get_business_info or check_contractor_license_status. Credentials are checkable at https://www.kolmo.io/verify.
