Access and checks

How we review

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

  • By default it can create, edit and delete wiki pages
  • The OAuth token grants access to the organization's whole wiki within its permissions

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

What it does

The server gives 33 typed tools for Yandex Wiki: full-text search on the same backend as the web UI's search box (up to 50 results per query), a full page lifecycle (create, update, append at top, bottom or an anchor, clone, delete with a restore token), comments, file uploads, and 11 write tools for dynamic tables (grids): rows, columns, cells, copying and sorting. Every tool ships a JSON schema for input and output plus read-only, destructive or idempotent safety annotations. A server-side WIKI_READ_ONLY=true flag simply does not register the write tools, so the agent cannot call them at all. It runs over stdio for desktop clients and over streamable-http with Docker and optional multi-user OAuth for teams.

Who it is for. For teams keeping their docs in Yandex Wiki who want to search and edit pages through an agent.

Good fit when

  • You need full-text search across the wiki with the same quality as the web UI
  • You need to safely give an agent read-only access via WIKI_READ_ONLY without letting it edit pages
  • You need to work with dynamic tables (grids): rows, columns, sorting

Not a fit when

  • You need an official Yandex server: this is an unofficial project, not affiliated with or endorsed by Yandex
  • You have no Wiki-scoped OAuth token and organization ID: the server will not connect without them

Transport
stdio, http
Authentication
OAuth

Environment variables

WIKI_TOKEN required, secret
Yandex OAuth token with Wiki access.
WIKI_ORG_ID required
Organization ID in Yandex 360.
WIKI_READ_ONLY
true disables registering write tools, making the server read-only.

Limitations

This is an unofficial project that runs on the same API as the web UI and is not endorsed by Yandex. Deleting a page returns a restore token, but write tools are active by default unless you explicitly set WIKI_READ_ONLY=true. The multi-user OAuth mode is only needed for a team HTTP deployment; local stdio use needs just one token.

How to disable. Remove the server from your MCP client config.

FAQ

How do I restrict the server to read-only?

Set the WIKI_READ_ONLY=true environment variable; write tools then are not registered and the agent cannot call them.

Is this an official Yandex server?

No, the README states plainly that the project is not affiliated with or endorsed by Yandex.
