# marktplaats-mcp

**marktplaats-mcp** is an MCP server that lets Claude, Cursor, Codex, opencode and every other MCP client search Marktplaats and 2dehands, the Dutch and Belgian second-hand classifieds. Find bargains, vet sellers, browse categories and monitor new listings in plain language.

## ✨ Features

- 🔍 **Powerful search**: free text, categories, price range, condition, distance from a postal code, recency, sorting
- 🇳🇱🇧🇪 **Two marketplaces, one server**: marktplaats.nl (Netherlands) and 2dehands.be (Belgium) via a `site` parameter
- 📄 **Full listing details**: complete description, all photos, view and favorite counts, listing age
- 🛡️ **Seller vetting**: verified bank account, identity and phone, review score
- 🔔 **New-listing monitoring**: poll for ads placed after a timestamp with a stateless cursor
- 🧠 **Built for LLMs**: compact token-efficient output, paid promotions filtered out, structured results, pagination hints
- 🔁 **Resilient**: retries with exponential backoff, jitter and `Retry-After` handling
- 🔓 **No account, no API key**

## 🚀 Quickstart

The only prerequisite is [uv](https://docs.astral.sh/uv/) (`brew install uv` or `curl -LsSf https://astral.sh/uv/install.sh | sh`).

**Claude Code**, one command:

```bash
claude mcp add marktplaats -- uvx marktplaats-mcp
```

Then ask: *"Search Marktplaats for an OLED TV under €400 near 3011 AB."*

</p>

## 🌐 Use on claude.ai (no install)

You can skip the terminal entirely. A hosted copy of this server runs at `https://marktplaats-mcp.jaspnerd.dev/mcp`, ready to plug into [claude.ai](https://claude.ai) in your browser or the Claude mobile app. Custom connectors work on every Claude plan, including Free.

1. Open [claude.ai](https://claude.ai) and go to **Settings → Connectors**.
2. Click **Add custom connector**.
3. Paste `https://marktplaats-mcp.jaspnerd.dev/mcp` as the URL and click **Add**. No account or key needed.
4. Ask Claude: *"Search Marktplaats for an OLED TV under €400 near 3011 AB."*

The hosted endpoint runs the same code as the PyPI package, rate-limited per client. If you'd rather have requests come from your own machine, install it locally below.

## 📦 Install in your favorite client

Every config runs the same stdio server via `uvx marktplaats-mcp`.

<details>
<summary><b>Claude Desktop</b></summary>

Add to `claude_desktop_config.json` (macOS: `~/Library/Application Support/Claude/`, Windows: `%APPDATA%\Claude\`), then fully restart Claude Desktop:

      "command": "uvx",

## 🧰 Tools

| Tool | What it does |
|---|---|
| `search_listings` | Search with query, category, price range, condition, distance, recency, sorting and pagination |
| `get_listing_details` | Full ad: complete description, all images, view and favorite counts, listing age |
| `get_seller_profile` | Trust signals: verified bank, identity and phone, review score and count |
| `list_categories` | Browse the category tree (names + ids) used for filtering |
| `check_new_listings` | Newest-first monitoring with a stateless cursor: returns only ads placed after `since` |

All five tools are read-only and carry the matching MCP annotations, so clients skip the confirmation prompts.

### Example prompts

- *"Find a second-hand iPhone 15 under €600 in as-good-as-new condition, sorted by price."*
- *"Search 2dehands for a bakfiets within 20 km of postcode 2000 Antwerpen."*
- *"Is seller 12345 trustworthy? Check their profile."*
- *"Check for new 'vintage lamp' listings since my last check and summarize the interesting ones."*

## ❓ FAQ

**Does this need a Marktplaats account or API key?**
No. It uses the same public JSON endpoints the website itself uses.

**Is this an official Marktplaats product?**
No. This is an independent open source project with no ties to Marktplaats or Adevinta. The underlying API is undocumented and may change. The server backs off politely on rate limits; keep your own usage reasonable.

**Why do I sometimes see fewer results than the limit?**
Paid promotions (DAGTOPPER/TOPADVERTENTIE) are filtered out by default. Pass `include_sponsored=true` if you want them.

**Which Python versions are supported?**
3.10 and up. CI tests 3.11 through 3.13 on Linux, macOS and Windows.

## 🗺️ Roadmap

- Persistent saved searches with price-drop detection
- Notifications (Discord/Telegram/ntfy via Apprise)
- Authenticated tools (your messages, favorites and bids)
- Docker image + Docker MCP Catalog
