At a glance

A skill your agent uses when the operator needs Megamarket data — search the catalog or read a product card.

  • The operator needs Megamarket data — search the catalog
  • SKILL.md covers When to use, Tools available, Gotchas and Privacy: the profile address…, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Read a product card

What it does

Megamarket Connector is an agent skill from Vladimir-Human/ru-marketplace-mcp. Use this skill when the operator needs Megamarket data — search the catalog or read a product card. Trigger on "мегамаркет", "megamarket", "цена мегамаркет". Always needs the operator's Chrome over CDP (ServicePipe IP block). Skip for non-Megamarket tasks.

Its SKILL.md is about 870 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Одиннадцать маркетплейсов и недвижимость Циан как MCP-серверы: Wildberries, Ozon, Яндекс Маркет, Детский мир, Авито, AliExpress, Taobao, Мегамаркет, Lamoda, DNS, Ситилинк, Циан… The licence is MIT.

When your agent uses it

  • The operator needs Megamarket data — search the catalog
  • Read a product card
  • Цена мегамаркет

Example prompts

  • “megamarket”
  • “/megamarket-connector”

What it can do on your machine

Read from SKILL.md and the folder at commit c17bd36. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Megamarket Connector loads about 873 tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 437 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~69
When it runs · the whole SKILL.md, loaded when a task matches
~873

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Use this skill when the operator needs Megamarket data — search the catalog or read a product card. Trigger on "мегамаркет", "megamarket", "цена мегамаркет". Always needs the operator's Chrome over CDP (ServicePipe IP block). Skip for non-Megamarket tasks.

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. Passing the ServicePipe challenge is not enough on its own: an anonymous browser that has cleared it still reads an empty items list. Real catalog data needs a browser that is actually logged in.

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 card

Not an MCP tool: megamarket_selfcheck() is a tri-state canary, where a code-7 refusal is inconclusive (transport), never drift. It is CLI-only — marketplace-mcp doctor runs every connector's canary at once.

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.
  • A missing price is null, never 0: price_rub: null means Megamarket had no usable price — treat it as no data, never as a free item.
  • Prices are address-dependent. _meta.warnings carries the address source only when it changes what the prices mean: address_source:profile (the operator's personal default address — personalized prices) or address_source:none (no delivery address resolved, so no offers are deliverable — expect the empty-items symptom). Both mark the response _meta.healthy=false. The default public city-level source (address_source:suggest from MEGAMARKET_ADDRESS) is the normal healthy case: no address warning.

Privacy: the profile address is opt-in

MEGAMARKET_USE_PROFILE_ADDRESS (default 0) decides whether the connector may read the private, account-gated /profileService/address/list endpoint from the operator's logged-in Chrome profile, to use the profile's default delivery address. Off — the default — it is never called: the address comes from the public suggest endpoint for MEGAMARKET_ADDRESS (Москва by default), and prices are city-level, not personalized. On, the profile's address list, its default flag and the region are read once per process, prices and availability match exactly what the operator sees on the site, and the search response carries address_source:profile plus a profile_address_read warning in _meta.warnings so the reader knows before quoting a price. The raw addressId never leaves the process.

Opt in when the operator asks for Megamarket prices "as I see them"; leave it off for neutral, city-level price research.

DSH activation

In DeepSeek Harness, the default profile exposes only compare_prices and compare_sources through the cheap compare mount. Per-marketplace tools and marketplace_sources require RU_MARKETPLACE_MCP_FULL=1 and a profile restart; do not call them in the default mode.
