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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00073 | $0.00333 |
| Opus 5 | $0.00036 | $0.00167 |
| Sonnet 5 | $0.00015 | $0.00067 |
| Haiku 4.5 | $0.00007 | $0.00033 |
Grade A, and why
megamarket-connector 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 12d 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
Megamarket Connector
Reads Megamarket via its internal mobile JSON API, POSTed from inside the operator's Chrome over CDP. ServicePipe gates the whole site by IP reputation: the API returns valid JSON, but the JSON is always the code-7 "отключите VPN" refusal with your own IP echoed back. Only a browser that has passed the ServicePipe challenge gets real catalog data.
When to use
- Search the Megamarket catalog by text
- One product's price, old price, availability, rating
Tools available
megamarket_search(query)— items + total count. price_rub None when absent.megamarket_card(item_id_or_url)— one product cardmegamarket_selfcheck()— tri-state canary; a code-7 refusal is inconclusive (transport), never drift
Gotchas
- A code-7 / VPN-error body is an IP block, not data — the connector maps it to transport_down with the fix inline.
- Run megamarket_selfcheck from your Chrome first: these endpoints were probed anonymously, and only a challenge-passed session confirms the in-browser shape.
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.
