Capabilities

Tools 12

compare_listings

Return normalized detail fields for 2–10 FlatHunt listings by numeric id in one read-only response. Includes prices, location, amenities, rental-policy flags, capacity, description, utilities, nearby distances, provider and tracking URLs for side-by-side comparison.

Discovered
create_alert

Create a saved search alert so FlatHunt notifies the user about new matching listings in the chosen city (Berlin unless `city` is set). Accepts housing, price, size, rooms, availability, canonical area ids, amenity and rental-policy filters. Email notifications are enabled by default; Telegram too when the user has linked Telegram on FlatHunt. Requires the alerts.write scope.

Discovered
delete_alert

Delete one or more of the current user's saved search alerts by numeric id. This is destructive and cannot be undone. Accepts 1–10 ids per call and requires alerts.write.

Discovered
get_listing

Get detailed information about a single FlatHunt listing by its numeric id (any city). Returns its description, amenities, rental-policy flags, capacity, stay terms, utilities, nearby distances, media, provider and tracking URLs. Availability and provider terms may change.

Discovered
list_alerts

List the current user's saved search alerts on FlatHunt, including each alert's numeric id, name and creation time when available. Requires alerts.read.

Discovered
list_areas

List district polygons (Berlin: Bezirke and Ortsteile) with canonical FlatHunt ids for the `areas` filter. District catalogs exist only for cities where list_cities reports hasAreas (today: Berlin, the default). For other cities search by city, post code or lat/lng/radiusKm. Returns id, name, slug, type and parent area information, with optional name and type filtering. Mitte exists both as a whole Bezirk (berlin:bezirk:mitte) and as a smaller Ortsteil (berlin:ortsteil:mitte). Charlottenburg is an Ortsteil; the parent Bezirk is Charlottenburg-Wilmersdorf.

Discovered
list_cities

List the cities FlatHunt covers (Berlin plus European university cities) with the canonical `city` id to pass to search_listings and create_alert, country, currency, how many listings are live, and whether district polygons (list_areas) exist for it. Berlin is the default city: omit `city` for Berlin. Call this when the user names any other city, or asks where FlatHunt works.

Discovered
list_saved_listings

List the current user's saved (favorited) FlatHunt listings. Requires the favorites.read scope.

Discovered
remove_saved_listing

Remove a listing from the current user's saved (favorited) listings by its numeric id. Requires the favorites.write scope.

Discovered
render_listings_widget

Return UI-ready cards and an interactive MCP Apps gallery for 1–10 FlatHunt listing ids. The tool refreshes current listing data and displays images, provider, price, availability and listing actions. Optional alertCriteria adds a saved-search control for the represented filters.

Discovered
save_listing

Save (favorite) a FlatHunt listing for the current user by its numeric id. Requires the favorites.write scope. Ownership and duplicate handling are enforced by FlatHunt.

Discovered
search_listings

Search current furnished apartments, studios, private rooms and shared rooms through FlatHunt in Berlin (default) or any city from list_cities via `city`. Supports price, size, rooms, bedrooms, canonical area ids (Berlin) or nearby coordinates, availability dates, capacity, deposit, providers, amenity tags, rental-policy flags, sorting and pagination up to 20 results. Returns normalized listing summaries and pagination metadata. Availability, prices and provider terms may change.
