Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00096 | $0.01033 |
| Opus 5 | $0.00048 | $0.00517 |
| Sonnet 5 | $0.00019 | $0.00207 |
| Haiku 4.5 | $0.00010 | $0.00103 |
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.

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 m², 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)"'

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

booli-fpx is a skill published in the GitHub repository chrischall/booli-mcp (4 stars, last pushed today), licensed MIT. It adds 96 tokens to every session and 1,033 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
