booli-fpx

booli-fpx is a skill for Claude Code from chrischall/booli-mcp. It costs 96 tokens per session (1,033 once invoked), scanned A, original, MIT.

A command-line workflow for querying Booli, a Swedish real-estate website, through the fpx browser-bridge tool. It can retrieve areas, homes for sale, sold prices and property details using Booli’s GraphQL interface.

In plain words
What is it for?
Use it to resolve Swedish locations, search current or sold listings, and inspect property details through one-off fpx commands.
Why use it?
It lets shell-based workflows access Booli when ordinary direct requests are blocked by its anti-bot protection. It uses an open Booli browser tab that has already passed that check.

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-fpx scanned grade A with 1 finding 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Booli via fpx (no MCP)

Booli fronts www.booli.se — including /graphql — with a Cloudflare managed challenge that 403s any plain curl/Node request. fpx routes the request through the user's own signed-in browser tab (the Transporter extension), which has already cleared the challenge, so the same anonymous GraphQL query succeeds. No Booli login is needed — just a normal open tab.

This is the same data the booli_* MCP tools return (money in SEK, areas in , rooms as a number), reached with one CLI call instead of a running server.

One-time setup

npm install -g @fetchproxy/cli           # provides `fpx`
fpx profile add booli --domain booli.se  # only the fetch capability is needed
fpx pair -p booli                        # prints a pair code → approve in Transporter

Requirements: the Transporter browser extension installed, with an open www.booli.se tab, and its Chrome Site access allowing booli.se. Pairing persists — after the first approval every later fpx call reuses it.

Core call

Every query is a POST of {"query": "...", "variables": {...}} to the GraphQL endpoint. Write the body to a file (a heredoc avoids shell-quoting the GraphQL string), then send it so stdout is the GraphQL JSON, ready for jq:

cat > /tmp/bq.json <<'JSON'
{ "query": "…", "variables": { … } }
JSON
fpx post-json 'https://www.booli.se/graphql' @/tmp/bq.json -p booli | jq '.data'

Ready-to-run query bodies (area lookup, for-sale search, sold search, property detail) with jq recipes are in references/graphql-queries.md. Exhaustive field lists live in the repo at src/graphql.ts — the operations here are compact, live-verified subsets.

The one rule: resolve the area first

Booli searches take a numeric area id (areaId), never a place name. Always resolve the name first, take the id, then search:

printf '{"query":"query($s:String!){areaSuggestionSearch(search:$s){suggestions{id displayName}}}","variables":{"s":"Nacka"}}' > /tmp/a.json
fpx post-json 'https://www.booli.se/graphql' @/tmp/a.json -p booli \
  | jq -r '.data.areaSuggestionSearch.suggestions[] | "\(.id)\t\(.displayName)"'
# 76      Nacka kommun

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.
