# booli-mcp

An MCP server for [Booli](https://www.booli.se), the Swedish property
portal — search active for-sale listings, sold prices (slutpriser),
resolve areas, and compute market statistics, all from Claude.

## 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](https://github.com/nullnet-app/contextmint-bridge/releases) — 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](https://github.com/chrischall/fetchproxy#extension) points to it.
   Its source is public at
   [nullnet-app/contextmint-bridge](https://github.com/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

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

## 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`](docs/BOOLI-API.md) for the underlying GraphQL API.
