A read-only, robots-clean MCP server over kleinanzeigen.de

Overview

AI-generated overview

Read-only MCP server for kleinanzeigen.de, the German classifieds site, letting an assistant search listings, open ads and look up commercial shops.

What you can do
  • Search one page of classified listings for a query
  • Open a single listing in full by its ad id
  • Read a commercial seller's profile and listings, or find shop slugs by name
  • Resolve category ids from a category name and location ids from a name or postcode, using bundled datasets
When to use it
Useful when an assistant needs to look up second-hand or classifieds offers on kleinanzeigen.de, inspect a specific ad, or check what a commercial seller offers. It is read-only, so it suits research and browsing rather than posting or managing ads.
Requirements
Runs locally over stdio; Node.js 22 or newer is required. Install via npx with the kanzeigen-mcp package, a Claude Code command, or an unsigned .mcpb bundle for Claude Desktop. No account, API key or environment variable is required; the optional KLEINANZEIGEN_MCP_RATE_LIMIT_MS sets the minimum gap between requests (default 1500 ms). Network access to kleinanzeigen.de is needed.
Before you install
The server makes live requests to kleinanzeigen.de, so keep the rate limit in mind and expect results to drift between pages; promoted listings repeat and a walk can miss or duplicate ads. Category and location lookups always return candidates, and shop matches may only be a mention in a profile, so verify ids before use. The Claude Desktop bundle is unsigned and has no update mechanism, so it stays at the downloaded version.

Installation

In SourceWeft

  1. Open Kleinanzeigen in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

Install

Node 22 or newer is required. Four channels install the same build from the same release — they differ only in who does the fetching, and nothing propagates between them.

npm / npx — any MCP client

The package is kanzeigen-mcp.

There is no install step and nothing to build. Point your client at npx and let it fetch the package on first run:

json
{  "mcpServers": {    "kleinanzeigen": {      "command": "npx",      "args": ["-y", "kanzeigen-mcp"]    }  }}

That block goes in your client's config file — claude_desktop_config.json for Claude Desktop, .mcp.json for Claude Code, the equivalent for anything else. Restart the client afterwards.

To verify by hand, without a client:

bash
npx -y kanzeigen-mcp

Claude Code

bash
claude mcp add kleinanzeigen -- npx -y kanzeigen-mcp

Any environment assignment goes before the --. Everything after the -- is the command Claude Code runs, so a variable placed there becomes an argument to npx rather than an environment variable:

bash
claude mcp add kleinanzeigen -e KLEINANZEIGEN_MCP_RATE_LIMIT_MS=3000 -- npx -y kanzeigen-mcp

Claude Desktop — the MCPB

Download kanzeigen-mcp-<version>.mcpb from the latest release and open it. Claude Desktop installs it and offers the one knob below as a form field, so nothing here needs a config file.

Two things are worth knowing before you pick it. The bundle ships unsigned, so the install dialog warns — self-signing fails its own verification, and a real certificate is a purchase nobody has made. And the format has no update mechanism: an installed .mcpb is as current as the day it was downloaded, and nothing will ever prompt you.

Claude Code plugin — the server and the skill

/plugin marketplace add IIxauII/kleinanzeigen-mcp/plugin install kanzeigen@kanzeigen

Configuration

KLEINANZEIGEN_MCP_RATE_LIMIT_MS — the minimum gap between requests, in milliseconds.

  • Unset means 1500 ms.
json
{  "mcpServers": {    "kleinanzeigen": {      "command": "npx",      "args": ["-y", "kanzeigen-mcp"],      "env": { "KLEINANZEIGEN_MCP_RATE_LIMIT_MS": "3000" }    }  }}

Development

Run from a clone. This is the development path rather than an install channel — it is the only one that yields a tree the drift check and the fixture-capture scripts can run in.

bash
git clone [email protected]:IIxauII/kleinanzeigen-mcp.gitcd kleinanzeigen-mcpnpm installnpm run build

npm run build produces a single-file ESM bundle at dist/index.js plus two sidecar datasets beside it. Point a client at it by absolute path:

json
{  "mcpServers": {    "kleinanzeigen": {      "command": "node",      "args": ["/absolute/path/to/kleinanzeigen-mcp/dist/index.js"]    }  }}
bash
npm test           # the whole suitenpm run typecheck  # tsc --noEmit, which is the real typechecknpm run build      # tsup, into dist/

Parser tests run against committed fixtures: hand-captured out of band by a dev-time script — never by the server — minimised to the DOM the parser actually reads, and redacted. The redaction rule is everything personal or identifying in the captured markup, including attributes the parser never reads: a pass aimed only at the fields the parser touches is how partner-ad ids and shop names once survived in tracking attributes. A test pins the rule.

Maintainer procedure — regenerating the two bundled datasets, running the drift check, and cutting a release — lives in docs/maintenance.md, because it addresses someone standing in a clone rather than someone who installed this.

Further reading: SPEC.md for the full contract, CONTEXT.md for the vocabulary every name in the codebase uses, and docs/adr/ for the decisions behind the posture.

search_listings

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.

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

find_category

Find categories

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

Parametersqueryrequired

find_location

Find locations

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

Parametersqueryrequired

find_shop

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.
