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 | $0.00055 | $0.00981 |
| Opus 5.5 | $0.00022 | $0.00392 |
| Sonnet 5.5 | $0.00011 | $0.00196 |
| Haiku 4.5 | $0.00006 | $0.00098 |
Grade A, and why
start-from-nothing 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 6d 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 — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.
From nothing to a running app
Most hosting integrations assume an account and an API key already exist. This one does not have to. The whole arc can start from zero.
The account
An Impreza account can be created without an e-mail address and without KYC.
When you reach the server with no credentials at all, it offers exactly one
tool, impreza_bootstrap_account, and nothing else — that is the lobby, and it
is the only thing an anonymous caller can do.
Two consequences worth stating plainly:
- Once you are authenticated, that tool is not in your list any more. If you are looking for it on a connected account, it is gone by design, not missing.
- The account comes back with a recovery code, and there is no e-mail to fall back on. If the customer loses it, we cannot restore the account for them — that is what "no e-mail" actually costs. Say this at the moment the code appears, not later.
The money, and what you can and cannot do with it
You cannot spend the customer's money from this conversation. Tools that would buy something — ordering a VPS, upgrading or resizing one, paying an invoice, registering or transferring a domain, buying WHOIS privacy — hand back a checkout link instead of charging. The customer completes the purchase on our page.
This is deliberate, and it is not a limitation to apologise for or try to route around. Do not look for another tool that "really" buys. There isn't one, and the connector attests to Anthropic that it does not execute financial transactions on a user's behalf.
What still works in chat is funding, because it moves no money by itself:
impreza_topupraises a funding invoice for an amount.impreza_topup_paymentshows the crypto address the customer sends from, by hand, out of their own wallet.impreza_topup_statussays whether it arrived.
Bitcoin and Monero. Nothing is debited from anyone by a tool call; the customer pushes the payment themselves.
Then the server
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.
