## MCP tools (6)

### `search_listings` (~156 tokens)

Search listings

One page of listings matching a search query. Promoted listings repeat on
every page; high-volume queries drift between pages, so a listing can be
missed or seen twice across a walk.

Input parameters:

- `ad_type` (string)
- `buy_now` (boolean)
- `category_id` (integer)
- `keywords` (string)
- `location` (string)
- `location_id` (integer)
- `max_price` (number)
- `min_price` (number)
- `page` (integer)
- `poster_type` (string)
- `radius` (integer)
- `shipping` (boolean)
- `shipping_carrier` (string)
- `sort` (string)

Output parameters:

One listing in full, by ad id.

Input parameters:

- `ad_id` (string, required)

Output parameters:

- `ad_id` (string)

- `images` (array)
- `listing_type` (string)
- `location_id`
- `location_name`
- `postcode`
- `posted`
- `price`
- `seller` (object)
- `source_url`
- `stale` (boolean)
- `stale_reason` (string)
- `status` (string)
- `title` (string)
- `url` (string)

### `get_shop` (~86 tokens)

Get shop page and inventory

Profile and listings for one COMMERCIAL seller. Private sellers have no
shop page and cannot be reached by this server.

Input parameters:

- `category_id` (integer)
- `keywords` (string)
- `location_id` (integer)
- `max_price` (integer)
- `min_price` (integer)
- `page` (integer)

- `source_url`
- `stale` (boolean)
- `stale_reason` (string)
- `status` (string)

### `find_category` (~54 tokens)

Find categories

Category ids matching a name. Always returns candidates — names and slugs
collide, so only the numeric id identifies a category.

Input parameters:

- `query` (string, required): A German category name, optionally qualified as "Parent > Child".

Output parameters:

- `count` (integer)
- `fetched_at` (string)
- `matches` (array)
- `source_url`
- `stale` (boolean)
- `stale_reason` (string)

### `find_location` (~102 tokens)

Find locations

Location ids matching a name or postcode. Always returns candidates — a
postcode can map to several locations.

Input parameters:

- `query` (string, required): A German place name, optionally qualified as "Bundesland > Ort". A five-digit postcode matches nothing: the postcode layer's ids are absent from every source this dataset may read. Pass a postcode to…

Output parameters:

- `count` (integer)
- `fetched_at` (string)
- `matches` (array)
- `source_url`
- `stale` (boolean)
- `stale_reason` (string)

### `find_shop` (~100 tokens)

Find shops

Shop slugs for COMMERCIAL sellers matching a name. Makes a live request,
unlike the other resolvers. A match may be a mention in a shop's profile
text rather than its name, so check before using one.

Input parameters:

- `category_id` (integer)
- `location_id` (integer)
- `name` (string, required): The commercial seller's name, passed to the directory's full-text search unchanged.
- `page` (integer)

Output parameters:

- `count` (integer)
- `fetched_at` (string)
- `matches` (array)
- `page` (integer)
- `page_size` (number)
- `source_url`
- `stale` (boolean)
- `stale_reason` (string)
