How we review

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

  • Can add sites, add and remove sitemaps, and trigger recrawl once confirm: true is passed
  • An OAuth token with access to every site in the account sits in the client config

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

What it does

The server covers nearly the whole Yandex Webmaster v4 API: diagnostics, indexing history and samples, SQI, search-URL events, sitemaps, important URLs, quota-limited recrawl, popular queries and their history, and external and broken internal links. Instead of a host_id like http:example.com:80, a site can be named simply example.com or пример.рф, the server resolves both ASCII and Unicode (IDN) forms. Every mutating tool without confirm: true returns a preview of the exact request that would be sent, not an actual change. Common Yandex error codes are mapped to plain-language hints: bad token, unverified host, rate limit, recrawl quota.

Who it is for. For people who care about protection from accidental writes and want to call sites by plain domains rather than the internal host_id format.

Good fit when

  • It matters that a Webmaster write requires explicit confirmation instead of firing on the first call
  • You need Cyrillic (IDN) domains in requests alongside Latin ones
  • You need broad API coverage: SQI, search-URL events, important-page history

Not a fit when

  • You need in-chat login without a pre-created OAuth app
  • A handful of basic tools is enough, 29 may be excessive

Authentication
API key

Environment variables

YANDEX_WEBMASTER_TOKEN required, secret
OAuth token from an app with the Yandex.Webmaster permission, sent as Authorization: OAuth

Limitations

Needs a pre-created OAuth token from an app with Yandex Webmaster permissions, there is no in-chat login. The project honestly describes itself as a rewrite of the third-party theyahia/yandex-webmaster-mcp package, fixing two bugs (a wrong auth header and a URL base-path error). Not an official Yandex server.

How to disable. Remove the yandex-webmaster block from your MCP client config.

FAQ

What happens calling a write tool without confirm?

The server returns a preview of the exact request that would be sent, with no real data change, the required confirm: true flag triggers the actual write.

Can a Cyrillic domain be used?

Yes, both ASCII and Unicode (IDN) forms resolve the same way, prefixing a scheme (https://…) helps disambiguate when both variants are registered.
