<h1 align="center">kleinanzeigen-mcp</h1>

An MCP server that lets an AI search [Kleinanzeigen](https://www.kleinanzeigen.de)
listings and pull ad and seller details. It wraps the Kleinanzeigen Android
app's API (`api.kleinanzeigen.de` / `gateway.kleinanzeigen.de`) and returns the
important fields to the AI.

## Highlights

- **Visual Listing Analysis**  
  Downloads and analyzes the actual ad photos, allowing vision-capable AI to inspect an item's **condition, wear, damage, completeness, and other visual details** instead of relying only on the seller's description.

- **Filters the API doesn't have**  
  `title_only`, `require` and `exclude` are applied server-side here and page on automatically, so an AI gets **the number of real matches it asked for** instead of re-searching to work around accessories and wrong variants.

- **From discovery to full inspection**  
  Find relevant ads, then retrieve **complete descriptions, itemised attributes, precise locations, seller reputation and all photos** for a deeper analysis.

## Tools

**`search_kleinanzeigen(query, ...)`**

Search listings by free-text keyword and/or category (id **or** name). Filters
for category-specific attributes, location/radius or postcode, price range,
offer/wanted, private/commercial, shipping and "Direkt kaufen", plus sorting
and paging.

Client-side filters, applied here over what Kleinanzeigen returns:
- `title_only`: every word of `query` must be in the title
- `require`: terms that must appear in title or description ("128gb" matches
  "128 GB" too)
- `exclude`: drop ads whose title carries these ("kabel" catches "Ladekabel",
  "pro" spares "Prozessor")

Returns a trimmed list of hits plus `total` / `next_page` / `has_more`.

**`get_ad_detail(ad_id)`**

Everything about one ad: full description, precise location, category,
attributes, shipping options, all images and the seller's rating.

**`get_ad_images(ad_id, max_images=4)`**

Download an ad's photos server-side and return them as real image content
(base64), so a vision-capable client sees the pictures instead of just URLs.
Handy when you want to actually look at a listing.

**`get_seller_info(seller_id)`**

Who is selling: name, private vs commercial, member-since date, ad counts,
followers, badges and Kleinanzeigen's reputation score.

**`search_locations(query)`**

Look up location/region ids for `search_kleinanzeigen`'s `location_id` filter
by name prefix.

**`get_category_filters(category_id)`**

List the category-specific attribute filters `search_kleinanzeigen`'s
`attributes` argument takes for one category, straight from Kleinanzeigen's
own search-options schema.

**`list_categories(query)`**

Browse Kleinanzeigen's category tree to find the category ids
`search_kleinanzeigen` takes. The full tree ships with the server in
`data/categories.json`. Note the tree stops fairly high up: a finer cut like
"Grafikkarten" is an attribute value from `get_category_filters`, not a
category.

## Setup

Requires Python 3.9+.

```bash
pip install -r requirements.txt
```

## Run

```bash
python main.py
```

The server starts over streamable HTTP and prints where it's listening:

```
Starting kleinanzeigen-mcp server on http://127.0.0.1:8000/mcp
```

Point your MCP client at that URL. Host, port and path live at the top of
`main.py`.

## Use it from Claude Desktop

Claude Desktop launches MCP servers over stdio, so bridge to this HTTP server
with [`mcp-remote`](https://www.npmjs.com/package/mcp-remote) (needs
[Node.js](https://nodejs.org)):

1. Start the server (`python main.py`) and leave it running.
2. In Claude Desktop open **Settings > Developer > Edit Config**; that reveals
   `claude_desktop_config.json`. Open it and add the `kleinanzeigen` entry:

   ```json
   {
     "mcpServers": {
       "kleinanzeigen": {
         "command": "cmd",
         "args": ["/c", "npx", "-y", "mcp-remote", "http://127.0.0.1:8000/mcp"]
       }
     }
   }
   ```

   On macOS/Linux drop the Windows wrapper: use `"command": "npx"` with
   `"args": ["-y", "mcp-remote", "http://127.0.0.1:8000/mcp"]`.
3. Save the file and **restart Claude Desktop**.

## Notes
- Search quirks worth knowing: `total` is capped at 10000 by Kleinanzeigen (so
  that value means "at least"), ads flagged `is_top_ad` are paid placements
  pinned above the sort order (`include_top_ads=False` for an honest price
  ranking), and a `null` price means "zu verschenken" or "VB" -- see
  `price_type`.
- `data/categories.json` is a flattened snapshot of Kleinanzeigen's category
  tree (title, id, children), built by `scripts/build_categories.py` from the
  live `api/categories.json` (which ships the tree wrapped in JAXB envelopes
  and a single "Alle Kategorien" pseudo-root). Re-run it if Kleinanzeigen
  changes their categories.
- API details, including the auth scheme and the Akamai finding, are
  documented in [`search_api.md`](search_api.md).
- This uses Kleinanzeigen's internal mobile API, not an official one. Be nice to it.
