## MCP tools (6)

### `search_permits` (~174 tokens)

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.

Input parameters:

- `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'.

### `list_sb9_inventory` (~133 tokens)

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.

Input parameters:

- `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.

### `list_adu_leads` (~101 tokens)

List parcels ranked by ADU (accessory dwelling unit) feasibility, including estimated max units, buildable square footage and the lot geometry behind the score.

Input parameters:

- `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.

### `list_redevelopment_leads` (~121 tokens)

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.

Input parameters:

- `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.

### `list_market_signals` (~112 tokens)

Search for high-signal real estate investment opportunities (teardowns, flips). Use this to find properties before diving into specific details.

Input parameters:

- `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')

### `get_property_intelligence` (~117 tokens)

Get detailed AI intelligence for a specific property. Returns teardown probabilities, flippability scores, comparable sales, and a developerROI field. Takes an id from list_market_signals. Treat developerROI as an AI screening estimate for ranking only, not as underwriting: it is a model output rather than arithmetic, and it disagrees materially with a build-to-zoning proforma on much of the inventory. Do not quote it as an expected return.

Input parameters:

- `id` (string, required): The unique identifier (ID) of the property to analyze
