Yandex Workspace MCP

A production-ready Model Context Protocol (MCP) server for integrating AI agents with Yandex Disk and Yandex Wiki.

This server provides a safe, unified interface for AI assistants to search, read, and intelligently update data in Yandex Disk and Yandex Wiki, without resorting to scraping or undocumented APIs.

Features

• Yandex Disk Integration: List files, search (via filtering), read metadata, obtain download/upload links, move, copy, delete, and create folders.

• Yandex Wiki Integration: Search pages, read full markdown content, browse page trees, manage attachments, fetch comments, and interact with dynamic tables. Optimistic locking is used to prevent accidental overwrites (revision checking).

• Unified Workspace Search: A single search_workspace tool allows agents to query both Disk and Wiki simultaneously.

• Security-First Architecture:

  • Read-only by default.

  • Granular permissions for read, write, and delete operations.

  • Path allowlisting (ALLOWED_ROOTS) to strictly confine AI operations.

  • Detailed, structured audit logging of all write/destructive operations.
