getBuckyMcpGuide

Call with no arguments on first contact. Optional `role`, `market`, and `scale` answer the first-call questions on a second call. Returns what this session should do next.

explainFeasibilityStatus

Explain one Bucky coverage or per-fact provenance status and the safe next action. This is a pure static lookup: it does not inspect an address, retrieve property data, or call a database, geocoder, A…

getFeasibilitySnapshot

Look up lot, zone, and building envelope for one street address in Canada or the US. Pass `address`. One address per call; cannot search or compare. Read exception before searching: its parcel zone la…

getBylawSection

Return the stored bylaw section text behind a snapshot citation. Pass `sectionIds` copied from `citations.*.knowledgeSectionId` on getFeasibilitySnapshot. Or pass `geoDivisionId` from `coverage.geoDiv…

screenLots

Find the lots in one live Bucky city that match a list. Pass `city` or `geoDivisionId` with `thesis` (plain words), `criteria` (square feet, dollars), or both; or pass a saved `profileId`. Returns cou…

findPlacesByMarket

Find which places to look at by their rental market: filter and rank every structured-live place on market facts and signals. Signed-in only; read scope. Pass `country` (CA or US; places rank only wit…

listSaved

List the signed-in user’s saved lots and projects. Returns at most limit rows (default 50, maximum 200), with folder ids and project stages. Use folderId to read one private folder. Copy a lot entry’s…

saveLot

Save one parcel by lotId without creating a project or running analysis. Copy lotId from a screenLots lot or assembly lot. Saving it again keeps the same save. Use preview=true first to inspect the re…

unsaveLot

Unsave one parcel by lotId. This also removes that saved lot from every folder. Projects are kept. Use preview=true first; this MCP tool does not provide Undo.

listSavedFolders

List the signed-in user’s private folders, most recently used first, with item counts. Returns at most limit rows (default 50, maximum 200). Folders can contain saved lots and projects from different …

createSavedFolder

Create a named private folder. A repeated create makes another folder. Use preview=true first and listSavedFolders to check an uncertain outcome before retrying.

renameSavedFolder

Rename a private folder by folderId. Pass name and use preview=true first to inspect the request without writing.

deleteSavedFolder

Delete a private folder by folderId and remove its memberships. Its lots stay saved and its projects are kept. Use preview=true first; this MCP tool does not restore deleted folders.

addSavedFolderItem

Add exactly one saved lot or project to a private folder. Pass folderId and target with savedLotId (a save id from listSaved) or projectId. Repeating the same membership is safe. Use preview=true firs…

removeSavedFolderItem

Remove exactly one saved lot or project from a private folder. Pass folderId and target with savedLotId or projectId. The lot stays saved and the project is kept. Use preview=true first.

proposeResultFlags

Suggest that results of one saved search are not a fit, for the user to confirm or reject on the result row. Signed-in only; write scope. Pass `profileId` and 1–25 `proposals` { lotId, reasonCode, evi…

runFeasibilityAnalysis

Enqueue a fresh deterministic analysis run for a saved project. Pass `projectId`, or `project` with the name the user said; with neither, the result lists their projects and nothing is queued. Returns…

getProjectContext

Load one project with analysis envelope, compact agentStatus, document summaries, evidence summaries, the project memory digest, and external_ref when the project was imported from another system. Pas…

saveToProject

Create a project (`create`), attach lots (`attach_parcels`), or attach a knowledge reference (`attach_reference`). Pass `projectId` or `project`; with neither, the result lists projects and writes not…

updateProject

Patch project metadata (name, lifecycle status, externalRef). Pass `projectId`, or `project` with the name the user said; with neither, the result lists their projects and nothing is written. preview=…

setProjectMapListing

Put a project on the public Bucky map, or take it off. Pass `projectId`, or `project` with the name the user said; with neither, the result lists their projects and nothing is published. Listing publi…

produceProjectReport

Compose a project report PDF. Pass `projectId` or `project`; with neither, the result lists projects and no meter is spent. preview=true composes without spending. confirm=true exports, spends records…

submitBuckyFeedback

Open a human-reviewed feedback form and submit it to the Bucky product team. Call only when the user explicitly asks to send feedback, report a problem, suggest an improvement, or praise something. Th…

previewSiteCoverage

Free preview, no sign-in needed. For one street address in Canada or the US, it says whether Bucky covers the place and which zoning facts it holds for the lot (lot boundary, zone, height, density, se…

cityInventory

Public city catalogue inventory. Pass exactly one of: cityName, lat and lng together, or geoDivisionId. A city name with multiple matches returns choices; after the user chooses, call again with that …

uiGetAnalysisStatus

Return only the analysis `agentStatus` for a project. Cheap enough to poll. Used by the Bucky app view; the model should call getProjectContext instead.
