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 ContextMint Bridge browser 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

Install ContextMint Bridge from its releases page — Chrome: download the chrome zip, unzip it, and load it unpacked at chrome://extensions (Developer mode). Safari isn't available yet (it will ship inside the ContextMint app, which has no public download), so use Chrome for now. Keep a www.booli.se tab open.

ContextMint Bridge is the fetchproxy browser extension under its new name, from the same maintainer — fetchproxy's own README points to it. Its source is public at nullnet-app/contextmint-bridge: build it yourself, or check a release zip against the .sha256 file published beside it (shasum -a 256 -c contextmint-bridge-chrome-<version>.zip.sha256).
On the first request, approve the one-time pairing prompt in ContextMint Bridge.
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 extension is linked, pair_pending (approve the pair code it names), or extension_disconnected.

Tools

Tool	What it does
`booli_search_areas`	Resolve a place name to Booli area ids
`booli_search_listings`	Search active for-sale listings by area + filters
`booli_get_listing`	Full detail for one property (active or sold) by residence id
`booli_search_sold`	Search sold listings (slutpriser) with final prices
`booli_market_stats`	Median/average sold-price statistics for an area
`booli_healthcheck`	Probe 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.
