## MCP tools (5)

### `kleinanzeigen_search` (~238 tokens)

Search Kleinanzeigen listings

Search by keyword, location, radius and price. Returns listing summaries — id, title, price, location, teaser and URL. Follow up with kleinanzeigen_get_listings_batch for full descriptions and seller details. Every filter is optional, but a search with neither query nor location returns an arbitrary slice of the site and is rarely useful.

Input parameters:

- `location` (string): City name or German postal code, e.g. 'Berlin' or '10115'
- `maxPrice` (integer): Maximum price in EUR
- `minPrice` (integer): Minimum price in EUR
- `pages` (integer): Result pages to fetch, ~25 listings each. Default 1, max 5.
- `publishedAfter` (string): Only listings published at or after this local ISO 8601 datetime, e.g. '2026-08-01T00:00:00'. Also stops paging once older listings appear.
- `query` (string): Search terms, e.g. 'ThinkPad T14' or 'Fahrrad 28 Zoll'
- `radiusKm` (integer): Search radius around `location` in kilometres

### `kleinanzeigen_search_by_url` (~159 tokens)

Search from a Kleinanzeigen URL

Search using a Kleinanzeigen URL, preserving all of its filters. Use this when the user pastes a Kleinanzeigen search link. Category URLs encode filters that kleinanzeigen_search cannot express — vehicle make, model year, fuel type, room count — and this keeps every one of them. Page numbers are injected automatically.

Input parameters:

- `pages` (integer): Result pages to fetch, ~25 listings each. Default 1, max 5.
- `publishedAfter` (string): Only listings published at or after this local ISO 8601 datetime, e.g. '2026-08-01T00:00:00'. Also stops paging once older listings appear.
- `url` (string, required): A kleinanzeigen.de search or category URL

### `kleinanzeigen_get_listing` (~118 tokens)

Get full listing detail

Fetch the full detail page of one listing: complete description, price, seller profile, location, images, category path and category-specific attributes. For more than one listing use kleinanzeigen_get_listings_batch instead.

Input parameters:

- `includeViewCount` (boolean): Also fetch how many times the ad was viewed. Costs one extra request and increments the seller's counter, exactly as opening the page in a browser would.
- `listing` (string, required): Numeric listing id (e.g. '3487590681') or a full kleinanzeigen ad URL

### `kleinanzeigen_get_listings_batch` (~101 tokens)

Get full detail for several listings

Fetch full details for several listings in one call — the normal follow-up to a search. Failed ids are reported in `errors` rather than failing the whole call, so a deleted listing does not lose you the rest.

Input parameters:

- `includeViewCount` (boolean): Also fetch view counts. Doubles the number of requests this call makes.
- `listings` (array, required): Listing ids or ad URLs, typically from a search. At most 20.

### `kleinanzeigen_parse_search_url` (~91 tokens)

Explain a Kleinanzeigen search URL

Explain which filters a Kleinanzeigen URL encodes, without scraping it. Returns the filters that map onto kleinanzeigen_search arguments plus any that do not — handy for telling the user what a link actually searches for, or for deciding whether kleinanzeigen_search is enough or kleinanzeigen_search_by_url is required. Makes no network request.

Input parameters:

- `url` (string, required): A kleinanzeigen.de search or category URL
