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 | $0.00075 | $0.00693 |
| Opus 5 | $0.00037 | $0.00347 |
| Sonnet 5 | $0.00015 | $0.00139 |
| Haiku 4.5 | $0.00007 | $0.00069 |
Grade A, and why
marketplace 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.
This is a copy
94% identical to marketplace — 32 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 49 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Unified Marketplace Server
One server mounting every installed connector as a namespaced toolset:
wb_*, ozon_*, yandex_*, detmir_*, avito_*, taobao_*, megamarket_*,
lamoda_*, dns_*, citilink_* plus compare_prices / compare_sources and its
own marketplace_sources. Tool names keep their prefixes, so habits and configs
carry over — but the operator wires a single marketplace entry instead of ten. The
server exposes 42 tools: 41 mounted plus marketplace_sources.
When to use
- "Where is X cheapest" — compare_prices fans out across all searchable sources
- Client setup: one config entry, not ten
- Health overview: the CLI's
doctorruns every selfcheck at once - A source came back empty and you can't tell installed-but-quiet from never-loaded

marketplace_sources
Tools
marketplace_sources()— no arguments; returns{mounted, skipped, mounted_count, skipped_count, server_version}.skippedmaps a source name to the import error that dropped it, usually a missing dependency. Connectors are imported defensively, so a missing dep removes a marketplace instead of killing the server — but from the client an absent source looks identical to one that found nothing. Call this to tell the two apart: a name inskippedwas never queried at all.
Operator CLI
marketplace-mcp install [client]— print the exact mcpServers JSON to paste. From a source checkout it prints the real filesystem path of that checkout, so there's no/path/to/kettu-marketplace-mcpplaceholder to hand-edit; installed as a wheel, it prints the console-script paths on PATH instead.clientmust be one ofclaude,claude-code,cursor— an unknown name is rejected, not answered with a Claude block.marketplace-mcp doctor [--status-file path]— per-source health plus a CDP session probe, with an optional machine-readable JSON snapshot for monitoring. Exit codes are meaningful for cron and CI:0everything healthy,1a parser drifted (the alarm — someone has to look),2nothing drifted but at least one source couldn't be judged (blocked, no CDP, wrong region). "Couldn't check anything" is a2, never a0.
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.
