This server has a remotely hosted endpoint. Open its connector listing for connection details, authentication requirements, and setup instructions:
Cited site feasibility and pre-development project workflows for Canada and the United States, as a plugin and a hosted MCP server.
Give it a street address and it returns the lot, the zone, the permitted uses, and the material envelope — setbacks, height, coverage, density — with each value carrying its own provenance. A setback the bylaw does not limit and a setback Bucky could not extract are different answers, and they stay different.

Add as a custom connector in ChatGPT's developer-mode Connectors settings, or at grok.com/connectors → New Connector → Custom.

Four skills, and one MCP connector:
Skill | For |
| Zoning, lot, setback, and height lookup for one address |
| Save a site, attach its parcel, run analysis |
| Prepare and export a cited report |
| Interpret a coverage or provenance status |
Two tools work with no account, so you can confirm the connection before signing
in: getBuckyMcpGuide and explainFeasibilityStatus.
Everything else uses Bucky's OAuth browser flow. You never paste a token. Connected apps are listed at Settings → Connected apps, with what each can do and when it was last used; disconnecting takes effect on the next request rather than whenever a token expires.
Account-scoped tools need a Professional plan or prepaid developer credit.
Coverage varies by jurisdiction. Results are preliminary decision support — not a permit, an appraisal, a guarantee, or a legal, engineering, or architectural opinion.
This repo is a mirror. The source of truth is Bucky's monorepo, and changes
made here are overwritten on the next sync. Open an issue rather than a pull
request, or send feedback through the submitBuckyFeedback tool — it goes to a
human.
