Blue Crane Forms & Tax MCP Server
To our knowledge, the first MCP server built for Canadian contractor
compliance — and the first anywhere to combine contractor paperwork with
provincial trades tax math in one agent toolkit. Built by
Blue Crane Works, Hamilton, Ontario.
A remote Model Context Protocol server
exposing 126 Canadian contractor forms — Ontario, Alberta, BC,
Saskatchewan, and Manitoba statutory worksheets plus Canada-wide site
paperwork — with regulatory citations verified against the governing acts,
plus 2026 contractor tax estimates by province running the sourced math
from tradestaxcalculator.ca.
Hosted endpoint (no auth, no keys):
Transport: MCP Streamable HTTP (JSON-RPC 2.0), stateless. Built as a
single-file Cloudflare Worker with zero dependencies.
Tools
Tax responses carry a dated-source disclaimer — planning estimates, not tax
advice. Every form is free to fill and print at
bluecraneworks.ca/tools — the server
always returns the free link.
Connect it
Claude: Settings → Connectors → Add custom connector →
https://mcp.bluecraneworks.ca/mcp
Any MCP client: point a Streamable HTTP transport at the endpoint.
Discovery: server card.
Clients that can only launch a local server
The endpoint above is the real server and pointing a client at it directly is
always the better route. For stdio-only clients, the included Dockerfile
bridges stdin and stdout to the hosted endpoint with
mcp-remote, so the tools it exposes
are the live ones rather than a copy that can drift:
Verified against the live server: initialize returns bluecrane-forms 1.1.0
and tools/list returns all eight tools.

Notes
- The forms are preparation worksheets and on-site records — Blue Crane
does not file anything with any ministry or regulator.
- Statutory citations are kept at the level verified against the source
regulation; guidance is not legal advice.
- This repo contains the server code. The form compendium data and the
sourced tax dataset are © Blue Crane Works Inc. and ship with the hosted
server (registry:
ca.bluecraneworks/forms, v1.1.0).
