Yandex Wiki MCP server
MCP-сервер Яндекс Вики
Yandex Wiki official MCP: an agent searches and reads knowledge base pages, builds summaries and creates new pages on behalf of the employee
Medium risk
We rate an entry medium when the tool runs code, makes network calls or reads project files. Check what exactly it does before installing.
Why this level
- The agent acts as the employee and can create and edit wiki pages, not just read them
- A compromised OAuth or IAM token exposes the whole wiki within that employee's rights
Install
Manual install
claude mcp add --transport http wiki-oauth https://mcp.wiki.yandex.net --header "X-Org-Id: <идентификатор организации>" --header "Authorization: OAuth <токен>"Command from Yandex's official support article; for a Yandex Cloud IAM token use X-Cloud-Org-Id instead of X-Org-Id and Authorization: Bearer <token>.
This is third-party code. Review the repository files before installing.
What it does
The server gives an agent access to the corporate Yandex Wiki through a remote Streamable HTTP MCP. Requests run on behalf of the user whose token is used to connect and with that user's permissions: whatever a person can see in the wiki, the agent sees too. The tools let it search pages, read their content, build a summary across several pages, and create or edit pages. The organization is confirmed by a header carrying a Yandex 360 or Yandex Cloud identifier.
Who it is for. For employees of companies on Yandex 360 who want answers and summaries from the corporate knowledge base right inside a conversation with an agent.
Good fit when
- You need to quickly find a wiki page and get an answer from it
- You need a summary across several pages at once, without reading each one by hand
- You want an agent to create or extend wiki pages as it works
Not a fit when
- The company does not use Yandex 360 for business or Yandex Cloud with Wiki
- You need access without issuing a specific employee's token: the server always acts as that person, with their permissions
Example request
Find the developer onboarding page in our wiki and write a short summaryLimitations
You need a specific employee's Yandex 360 OAuth token or Yandex Cloud IAM token, and the exact authorization header format depends on the organization type. The docs explicitly warn against exposing the server with someone else's token or pasting real tokens into examples. The public reference does not list every tool and its parameters, only three actions: search and read pages, create and edit, build a summary.
How to disable. Remove the server from your MCP client configuration, for example with claude mcp remove wiki-oauth, and revoke the issued OAuth or IAM token in account settings.

README in short
Yandex's official support article describes the Wiki MCP server as part of Yandex 360: address https://mcp.wiki.yandex.net, HTTP transport, authorization via an OAuth token for Yandex 360 organizations or an IAM token for Yandex Cloud, with X-Org-Id or X-Cloud-Org-Id headers to identify the organization. It shows connection examples for Claude Code and Codex, and describes the tools as searching and reading pages, creating and editing, and building a summary across several pages. A separate block warns about the risk of exposing the server with someone else's token.
FAQ
On whose behalf does the agent act?
On behalf of the employee whose token is used to connect, strictly within that person's wiki access rights.
Can the server be shared across a whole team?
The docs explicitly advise against publishing a gateway with one shared token, each user needs their own.
