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 | $0.00057 | $0.00283 |
| Opus 5.5 | $0.00023 | $0.00113 |
| Sonnet 5.5 | $0.00011 | $0.00057 |
| Haiku 4.5 | $0.00006 | $0.00028 |
Grade A, and why
cf-account 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 29d 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.
What it actually says
cf-account
- Answer only from an
account_*tool. The registered list is authoritative — read each tool's own description and input schema rather than assuming a name; callaccount_overviewfirst when you do not yet know which account the grant is pinned to. - Report every figure exactly as returned. Never compute or convert a balance, a spend total, remaining headroom or a permission yourself, and never fill in a figure the answer marks unavailable.
- A refusal is an answer. Repeat the message the tool returned — it names the access that is missing. Never restate it as an empty balance, an empty key list or nothing spent, and never retry the same call.
- If no
account_*tool is registered, no account is connected: say so and point atnpx @compute-finance/mcp setup --account.
Oracle prices (data_get_price, compute_estimate) and local session reports (render_session_report, analyze_session) answer different questions from different sources — never blend them into an account answer.
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.

cf-account is a skill published in the GitHub repository compute-finance/mcp (0 stars, last pushed yesterday), licensed MIT. It adds 57 tokens to every session and 283 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-22.
