booli

booli is a skill for Claude Code, Codex from chrischall/booli-mcp. It costs 61 tokens per session (860 once invoked), scanned A, original, MIT.

A tool for searching and analysing Swedish property data from Booli, a Swedish real-estate website. It covers homes for sale, sold prices, areas and market statistics.

In plain words
What is it for?
Use it to find Swedish apartments and houses, resolve locations, compare asking and sold prices, and examine local housing-market statistics.
Why use it?
It avoids manually searching Booli and collecting property data from different pages. Queries may require a browser tab because Booli can block direct automated requests.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

booli scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Booli (booli.se)

Tools for the Swedish property portal Booli, reading its consumer GraphQL API. Money is in SEK, areas in , rooms as a number.

Setup — the browser bridge

booli.se is behind a Cloudflare bot wall that blocks server-side requests, so booli-mcp routes each query through your own signed-in www.booli.se browser tab via the fetchproxy bridge (the Transporter extension). No Booli login is needed — just a normal, Cloudflare-cleared page view.

  • Keep a www.booli.se tab open in the browser running the Transporter extension. On the first request, approve the one-time pairing prompt.
  • BOOLI_TRANSPORT picks the path: auto (default — tries a direct fetch first, falls back to the bridge when walled), fetchproxy (always the bridge), direct (fail if walled). The fleet shares WS port 37149 (BOOLI_WS_PORT).
  • Run booli_healthcheck to confirm the path is working.

Start with an area

Booli's searches scope by a numeric area id, not a place name. Resolve first, or pass a free-text location and the search tools resolve the top hit for you.

  1. booli_search_areas{ query: "Nacka" } → areas with area_id and display_name. Pass an area_id into the search tools.

For-sale listings

  • booli_search_listings — search active listings by area_id or free-text location, plus optional min_list_price/max_list_price (SEK), min_list_sqm_price/max_list_sqm_price, min_rooms/max_rooms, min_living_area/max_living_area (m²), min_plot_area/max_plot_area, object_type (comma-separated: Lägenhet, Villa, Kedjehus-Parhus-Radhus, Fritidshus, Gård, Tomt/Mark), min_construction_year/max_construction_year, is_new_construction, sort + ascending. Paginated by page — check total_count/pages. Returns slim summaries by default (compact: false for full raw records).
  • booli_get_listing — full detail for one property by its residence id (the number in a booli.se/bostad/ URL, or a result's residence_id). Works for both active and sold properties.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
