Tools

• addSavedFolderItem ~642 tokens
  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 first.
• cityInventory ~588 tokens
  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 candidate geoDivisionId. Never pass a slug. Shows datasets grouped by topic as on file, not loaded y
• createSavedFolder ~428 tokens
  Create a named private folder. A repeated create makes another folder. Use preview=true first and listSavedFolders to check an uncertain outcome before retrying.
• deleteSavedFolder Deletes data · ~449 tokens
  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.
• explainFeasibilityStatus ~657 tokens
  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, AI model, or third-party API. Accepts exactly one of: live, live_unavailable, planned_not_live, geo_d
• getBuckyMcpGuide ~497 tokens
  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.
• getBylawSection ~752 tokens
  Return the stored bylaw section text behind a snapshot citation. Pass `sectionIds` copied from `citations.*.knowledgeSectionId` on getFeasibilitySnapshot. Or pass `geoDivisionId` from `coverage.geoDivisionId`, `zoneCode` from `zone.code`, and `sectionNumbers` such as 3.1 or 3.2. The markdown is the
• getFeasibilitySnapshot ~689 tokens
  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. Every envelope value carries a `status`. Never report `not_extracted` or `site_specific_schedule` as no limit or as zero — call `explainFeasibilityStat
• getProjectContext ~823 tokens
  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. Pass `include` for optional sections: tasks, members, insights, capital, visualEvidence. Default is non
• listSaved ~485 tokens
  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 id as savedLotId when filing it; lotId identifies its parcel. A saved lot is not a project.
• listSavedFolders ~433 tokens
  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 places.
• previewSiteCoverage ~534 tokens
  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, setbacks, permitted uses, overlays, parking): found, partly on file, or not on file. It returns no val
• produceProjectReport ~757 tokens
  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.exports, and is irreversible. Returns a signed download URL, never PDF bytes.
• removeSavedFolderItem ~638 tokens
  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.
• renameSavedFolder ~447 tokens
  Rename a private folder by folderId. Pass name and use preview=true first to inspect the request without writing.
• runFeasibilityAnalysis ~634 tokens
  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 immediately with `agentStatus` (`queued`, `running`, `current`, `failed`, or `none`) and a receipt
• saveLot ~476 tokens
  Save one parcel by lotId without creating a project or running analysis. Saving it again keeps the same save. Use preview=true first to inspect the request without writing.
• saveToProject ~1417 tokens
  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 nothing. For attach_parcels, pass a WGS84 GeoJSON polygon (up to 500 selected parcels), or copy `lot.pa
• screenLots ~7500 tokens
  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 countOutcome (exact, partial, or unavailable), screeningRunId, and selected lots ranked largest first w
• setProjectMapListing ~848 tokens
  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 publishes the build-lot centroid, the project name, its zone category, typology and lifecycle status to a
• submitBuckyFeedback ~582 tokens
  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. The server asks the MCP client to show the form; nothing is saved unless the human accepts it. Do not
• uiGetAnalysisStatus ~444 tokens
  Return only the analysis `agentStatus` for a project. Cheap enough to poll. Used by the Bucky app view; the model should call getProjectContext instead.
• unsaveLot ~472 tokens
  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.
• updateProject ~846 tokens
  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=true returns the field-level diff and writes nothing. A write returns a receipt; undoOperationId res
