Access and checks

How we review

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

  • Can add and remove sites, sitemaps and trigger recrawl without a separate confirmation step
  • A broad-permission Webmaster OAuth token is passed through an environment variable

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

What it does

The server covers almost the entire Yandex Webmaster API v4.1: sites and adding or removing them, verification status and owner lists, a summary with ИКС quality scores and its history, popular queries (top 3000) and analytics, recrawl quota and submission, diagnostics, indexing history by HTTP status, important-URL monitoring, pages in search with history and samples, auto-discovered and manually added sitemaps, and external and broken internal links. The server URL-encodes the host_id in scheme:domain:port form itself when sending API requests.

Who it is for. For SEO specialists who want the widest possible Yandex Webmaster API coverage in a single Python server.

Good fit when

  • You need the full Webmaster spectrum: from diagnostics and ИКС to important-URL monitoring and external links
  • Installing via pip install -e . and running the Python server directly is fine
  • You need call examples with real date and indicator parameters

Not a fit when

  • You need write operations gated by explicit confirmation, no confirm flag is documented
  • You need in-chat login without pre-creating an OAuth app

Transport
stdio
Authentication
API key

Environment variables

YANDEX_WEBMASTER_API_KEY required, secret
OAuth token with webmaster:hostinfo and webmaster:verify scopes, valid for 6 months

Limitations

The OAuth token lasts 6 months and needs manual refresh. The README does not describe write operations being gated by a confirmation step. The host_id format (scheme:domain:port with no slashes) needs care when building requests manually.

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

FAQ

What is a host_id?

Yandex Webmaster's special site identifier format: scheme:domain:port with no slashes, e.g. https:example.com:443, not a regular URL.

How long does the OAuth token last?

Six months from issuance, after which it needs to be obtained again through the same oauth.yandex.ru/authorize link.

How is this Yandex Webmaster MCP different from other Webmaster servers?

The Python server covers almost all of Yandex Webmaster API v4.1 in 37 tools: sites, adding and removing, verification, owners, a summary with the quality index and its history, popular queries (top 3000), diagnostics, sitemaps and important URL monitoring.

What is host_id and how long does an OAuth token live?

host_id is a site identifier in Webmaster in the format protocol:domain:port, for example https:example.ru:443. Yandex sets the OAuth token lifetime at issue, see the Yandex OAuth docs for the current value. Install with pip install -e ., it works in Claude Desktop and Claude Code.
