About booli-mcp

booli-mcp is an MCP server for querying Swedish property listings and market data from Booli. It provides read-only searches and statistics, using a signed-in Booli browser session through ContextMint Bridge when direct access is blocked.

Key features

  1. 01Search active property listings
  2. 02Look up sold listings and prices
  3. 03Resolve place names to area IDs
  4. 04Get property details and market statistics
  5. 05Check data access and bridge status

Use cases

  1. 01Find homes for sale in a specified area
  2. 02Compare sold prices and area-level statistics
  3. 03Retrieve details for a particular property

MCP support

Exposes Booli area, listing, sold-price, property-detail, market-statistics, and health-check tools to MCP clients. Queries can use direct access or route through ContextMint Bridge using a signed-in Booli browser tab.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

Environment variables to set
BOOLI_TRANSPORTSelects the path: auto (default — direct fetch first, browser-bridge fallback when walled), fetchproxy (always the bridge), or direct.
BOOLI_WS_PORTOverride the fetchproxy WebSocket port (the fleet shares 37149).
FETCHPROXY_WS_HOSTBridge bind interface, a literal IP only (default 127.0.0.1). Keep on loopback; exists for a hosted child in its own network namespace.
FETCHPROXY_IDENTITY_DIRAbsolute path for the long-term bridge identity keypair (default ~/.fetchproxy/identity/). Exists for a host that runs a separate child per caller.

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Details

From the project README

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

  1. 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).

  2. On the first request, approve the one-time pairing prompt in ContextMint Bridge.

  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 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.

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
