The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_property_intelligence ~129
Get detailed AI intelligence for a specific property. Takes an id from list_market_signals. Returns teardown and flippability scores, a market heat index, an AI briefing, comparable-sale counts with an average price per sqft, and parcel enrichment (zoning, lot size, development class). Those scores rank candidates; none of them is a return. This endpoint carries no ROI figure at all: for that, read proformaROI from list_market_signals, which is arithmetic rather than a model estimate.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | The unique identifier (ID) of the property to analyze |
No output schema declared.
No examples provided.
list_adu_leads ~101
List parcels ranked by ADU (accessory dwelling unit) feasibility, including estimated max units, buildable square footage and the lot geometry behind the score.
| Name | Type | Req | Description |
|---|---|---|---|
| excludeBlockers | boolean | – | Drop parcels carrying any development blocker. |
| limit | number | – | Max rows to return. Clamped to your API key's tier ceiling. |
| minScore | number | – | Minimum ADU feasibility score, 0-100. Defaults to 60. |
No output schema declared.
No examples provided.
list_market_signals ~209
Search for high-signal real estate investment opportunities (teardowns, flips). Use this to find properties before diving into specific details. Each result carries proformaROI, a net teardown ROI computed by arithmetic rather than by a model, with a proforma object holding its inputs and assumptions ($400/sqft build, 5% cost of sale, build sized to the zoning envelope). Quote those assumptions alongside the number. null means not modellable, with unmodellableReason naming the missing input: treat it as unknown, never as zero. Negatives are normal here; most of this market does not pencil.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | – | Search for a specific address |
| city | string | – | Filter by city name (e.g. 'Atherton') |
| limit | number | – | Max rows to return. Clamped to your API key's tier ceiling. |
| market | string | – | Filter by market (e.g. 'sf-peninsula' or 'nantucket') |
No output schema declared.
No examples provided.
list_redevelopment_leads ~121
List underbuilt parcels: small, older homes using a low share of their allowable building envelope on sizable lots. Ranked by redevelopment score, with the FAR headroom that produced it.
| Name | Type | Req | Description |
|---|---|---|---|
| class | string | – | Narrow to scrape-and-rebuild candidates or expansion candidates. |
| excludeBlockers | boolean | – | Drop parcels carrying any development blocker. |
| limit | number | – | Max rows to return. Clamped to your API key's tier ceiling. |
| minScore | number | – | Minimum redevelopment score, 0-100. Defaults to 60. |
No output schema declared.
No examples provided.
list_sb9_inventory ~133
List active listings that are eligible for an SB 9 lot split or duplex conversion, with the per-parcel block reasons where they are not. California-only; this is a parcel-level buildability read, not a generic lead list.
| Name | Type | Req | Description |
|---|---|---|---|
| excludeBlockers | boolean | – | Drop parcels carrying any development blocker. |
| limit | number | – | Max rows to return. Clamped to your API key's tier ceiling. |
| minUnits | number | – | Only parcels supporting at least this many SB 9 units. |
| status | string | – | Filter by SB 9 status. Defaults to any non-blocked parcel. |
No output schema declared.
No examples provided.
search_permits ~174
Search issued building permits across the SF Peninsula and adjacent Silicon Valley cities. Filter by city, keyword (address, project type, scope description, contractor, architect or permit number) and minimum valuation. Use this to find what construction has actually been permitted at an address or in a city.
| Name | Type | Req | Description |
|---|---|---|---|
| city | string | – | City name, e.g. 'Menlo Park'. Partial matches allowed. |
| limit | number | – | Max rows to return. Clamped to your API key's tier ceiling. |
| minValuation | number | – | Only permits valued at or above this dollar amount. |
| offset | number | – | Row offset for paging. |
| q | string | – | Keyword matched against address, project type, scope description, contractor, architect and permit number, e.g. 'demolition' or '123 Main St'. |
No output schema declared.
