WHAT IT DOES

What datasets_housing_markets_facets does on Crawlora

AI agents call datasets_housing_markets_facets to retrieve information from Crawlora without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`q`	string	—	Full-text query over region name and city, max 256 characters
`facet`	string	Yes	Facet enum: region_type, state_code, property_type, parent_metro, parent_metro_code, income_vintage, is_latest, period_begin
`latest`	boolean	—	Filter for the most recent period per region and property type
`period`	string	—	Exact period start date filter, YYYY-MM-DD
`zip_code`	string	—	Exact zip code filter (zip-level rows only), e.g. 60616
`state_code`	string	—	Exact two-letter state code filter, e.g. CA
`region_type`	string	—	Region level enum: national, metro, county, city, zip
`max_inventory`	integer	—	Maximum active inventory
`min_inventory`	integer	—	Minimum active inventory
`property_type`	string	—	Property type enum: All Residential, Single Family Residential, Condo/Co-op, Townhouse, Multi-Family (2-4 Unit), Single Units Only
`max_median_dom`	number	—	Maximum median days on market
`min_homes_sold`	integer	—	Minimum homes sold in the period

RISK

Why datasets_housing_markets_facets is rated Low

RECOMMENDED RULE

The rule that runs datasets_housing_markets_facets safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Crawlora, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For datasets_housing_markets_facets, this is the rule to start with:

datasets_housing_markets_facets Allowed

datasets_housing_markets_facets is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

{
  "version": "1",
  "default": "deny",
  "tools": {
    "datasets_housing_markets_facets": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Crawlora, apply this rule, and every datasets_housing_markets_facets call is checked against it from then on.
