English | Nederlands

Finding a room in the Netherlands is brutal: good listings get 60+ replies within the hour. kamernet-mcp puts Kamernet, the largest Dutch platform for rooms, studios and apartments, inside your AI agent. The agent searches with your criteria, reads full listings in English and Dutch, ranks them against your budget, and tells you when something new appears.

You:    Find me a furnished room in Utrecht under €900, at least 15 m², and rank
        the top 3 by value for a working professional who needs registration.

Agent:  → search_listings(city="Utrecht", max_rent=900, min_size=15, ...)
        → get_listing(...) ×3
        → score-listing prompt
        Here are the top 3, with deposits, energy labels and red flags…

Quickstart

Requires uv (or plain pip). One command:

claude mcp add kamernet -- uvx kamernet-mcp

Then ask Claude to find you a room. For other clients, use an install badge or unfold yours below.

Install in Cursor Install in VS Code

claude mcp add kamernet -- uvx kamernet-mcp

{
  "mcpServers": {
    "kamernet": { "command": "uvx", "args": ["kamernet-mcp"] }
  }
}

{
  "mcpServers": {
    "kamernet": { "command": "uvx", "args": ["kamernet-mcp"] }
  }
}

{
  "mcpServers": {
    "kamernet": { "command": "uvx", "args": ["kamernet-mcp"] }
  }
}

codex mcp add kamernet -- uvx kamernet-mcp

[mcp_servers.kamernet]
command = "uvx"
args = ["kamernet-mcp"]

{
  "mcp": {
    "kamernet": {
      "type": "local",
      "command": ["uvx", "kamernet-mcp"],
      "enabled": true
    }
  }
}

pip install kamernet-mcp

Tools

* Only registered when KAMERNET_EMAIL / KAMERNET_PASSWORD are set; see Authenticated tools.

There is also a kamernet://filters resource listing all valid filter values, and a score-listing prompt: a weighted rubric (price, location, quality, privacy, long-term fit) with bilingual deal-breaker detection ("no internationals" / "geen internationals") that your agent uses to rank listings for you.

Configuration

Everything works with zero config. Optional environment variables:

Authenticated tools (experimental)

Searching needs no account. Replying to landlords requires a paid Kamernet premium account (that's Kamernet's paywall, not ours) and browser automation:

uvx --with 'kamernet-mcp[auth]' kamernet-mcp   # or: pip install 'kamernet-mcp[auth]'
playwright install chromium

Set KAMERNET_EMAIL and KAMERNET_PASSWORD in your MCP client's env block. Cookies are cached locally so login happens rarely.

[!WARNING] Automated replying violates Kamernet's terms of service and can get your account banned. Replies are hard-capped per session. Use it for messages you wrote and approved for one specific listing; a generic message sent to 50 landlords floods landlords and hurts your own chances. Use at your own risk.

How it works

Kamernet is a Next.js site. Its CSS class names change on every deploy, which is what killed most earlier Kamernet bots. This server skips them and reads the structured __NEXT_DATA__ JSON embedded in each public page: the same data the site renders from, and stable across frontend redesigns.

Politeness is enforced in code: a transparent User-Agent linking to this repo, a minimum 1-second delay between requests, no robots.txt-disallowed endpoints, and no tricks to evade rate limits. PRs that weaken this are rejected.

Development

git clone https://github.com/jasp-nerd/kamernet-mcp
cd kamernet-mcp
uv sync --all-extras
uv run pytest          # 40+ tests, no network needed
uv run ruff check .

Tests run against sanitized snapshots of real Kamernet pages (tests/fixtures/) plus FastMCP's in-memory client, exercising the full MCP protocol without a browser or network. See CONTRIBUTING.md.

Debug interactively with the MCP Inspector:

npx @modelcontextprotocol/inspector uv run kamernet-mcp
