How we review

Extended accessThe tool runs code or makes network calls and only reads external data.

  • The npx bridge forwards requests to marketscore.ru, which calls Wordstat on its side
  • Each request spends the prepaid service balance and changes nothing in your accounts

This is third-party code. Review the repository files before installing.

What it does

The package is a thin bridge to a hosted MCP server at marketscore.ru: the actual logic and Wordstat API calls run on the service side. Four tools: wordstat_suggest returns frequencies and related phrases with noise annotation (informational queries, job postings, geo-tails), addressable demand and ready negative keywords; wordstat_dynamics shows 24-month seasonality with a year-over-year trend; wordstat_cluster groups related phrases into an ad-group draft; wordstat_regions gives demand by region with an affinity index. Claude and ChatGPT connect by URL via OAuth; local clients use an npx bridge.

Who it is for. For marketers who want not a raw Wordstat dump but an already-annotated list, noise removed, with seasonality attached.

Good fit when

  • You want frequency data with the noise already filtered out and negative keywords ready
  • You need two years of seasonality with a verdict on when to launch
  • You need an ad-group draft built from related phrases

Not a fit when

  • You need a fully free source with no prepaid packs
  • You need direct access to the raw Wordstat API rather than through the service layer

Example request

Limitations

The service is paid: packs start at 100 requests for 20 rubles, one free request on sign-up, credits never expire. Without a balance the server exposes zero tools. The connector itself is open (MIT), but the matching logic and Wordstat API keys stay on marketscore.ru's side, you're trusting that service as a data provider.

How to disable. Remove the connector from your Claude or ChatGPT settings, or delete the wordstat entry from your local client's mcpServers.

FAQ

Do I need a Yandex Direct account?

No, this is a standalone keyword-research product; a Direct account is not required.

What happens when the balance runs out?

The server stops exposing tools until you top up with another request pack.

README in short

The bilingual README explains the difference from plain Wordstat scrapers, gives a pricing table, shows the URL-based connection for Claude/ChatGPT and the npx bridge for local clients, and mentions two sibling paid MCP servers on the same account, one for SEO metrics, one for Direct/VK/Avito ads.
