Booli.se real estate for Claude: search listings, sold prices, areas & market stats

Developer ToolsTypeScriptv2.1.11

booli-mcp

An MCP server for Booli, the Swedish property portal — search active for-sale listings, sold prices (slutpriser), resolve areas, and compute market statistics, all from Claude.

Developed and maintained by AI (Claude Code). Use at your own discretion and within booli.se's terms of use.

How it works

Booli fronts www.booli.se — including its GraphQL API — with a Cloudflare bot wall that blocks server-side clients. booli-mcp therefore reads Booli's consumer GraphQL API by routing each query through your own signed-in www.booli.se browser tab via the fetchproxy bridge (the Transporter extension), reusing your Cloudflare-cleared session. No Booli login is required — just a normal page view. All tools are read-only.

BOOLI_TRANSPORT selects the path: auto (default — direct fetch first, browser-bridge fallback when walled), fetchproxy (always the bridge), or direct. The fetchproxy fleet shares WS port 37149 (BOOLI_WS_PORT).

Setup

  1. Install the Transporter (fetchproxy) browser extension and keep a www.booli.se tab open.
  2. On the first request, approve the one-time pairing prompt in Transporter.
  3. Run booli_healthcheck to confirm the path is working. Its transport field says which leg served the probe (direct or fetchproxy) and, once the bridge exists, bridge.session_state says whether the Transporter extension is linked, pair_pending (approve the pair code it names), or extension_disconnected.

Install

// mcp config
{
  "mcpServers": {
    "booli": {
      "command": "npx",
      "args": ["-y", "@chrischall/booli-mcp"]
    }
  }
}

Tools

ToolWhat it does
booli_search_areasResolve a place name to Booli area ids
booli_search_listingsSearch active for-sale listings by area + filters
booli_get_listingFull detail for one property (active or sold) by residence id
booli_search_soldSearch sold listings (slutpriser) with final prices
booli_market_statsMedian/average sold-price statistics for an area
booli_healthcheckProbe the data path and report transport (direct / fetchproxy, the BOOLI_TRANSPORT mode) and, once the bridge is up, bridge (role, port, extension link session_state, pending pair code) with a next-step hint

Searches scope by area_id (from booli_search_areas) or a free-text location. Money is SEK, areas m². See docs/BOOLI-API.md for the underlying GraphQL API.
