Install

claude mcp add yandex-wiki \
  -e WIKI_TOKEN=your_token \
  -e WIKI_ORG_ID=your_org_id \
  -- uvx mcp-yandex-wiki

Requires uv.

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

What it does

The server connects an agent to an organization's Yandex Wiki API. In full mode the agent fetches a page by slug or URL, gets its text, creates new pages, updates existing ones and appends content. A separate mcp-yandex-wiki-ro command runs read-only, where writes return 403. Frequent reads can be cached in Redis, which is invalidated when a page changes.

Who it is for. For Yandex 360 teams that keep documentation in Wiki and want to work with it through an agent.

Good fit when

  • You want to give the agent context from internal Wiki docs
  • You want the agent to append reports or notes to Wiki pages
  • You need safe read-only Wiki access

Not a fit when

  • You need Wiki search, comments or permission management: no such tools
  • Your organization does not use Yandex Wiki

Example request

Read the Wiki page at this link and append a section with today's meeting summary

Limitations

Requires an OAuth token from your own oauth.yandex.ru app with Wiki scopes and an organization ID. Tools are limited to reading, creating, updating and appending pages. Caching needs a separate Redis.

How to disable. Remove it with claude mcp remove yandex-wiki or delete the entry from the client config. The token can be revoked in Yandex ID settings.

FAQ

Can I reuse a Tracker token?

The server accepts TRACKER_TOKEN and TRACKER_ORG_ID instead of WIKI_TOKEN and WIKI_ORG_ID if the token has Wiki scopes.
