mcp-yandex360

An MCP server for Yandex 360: Disk, Telemost and Messenger in one process, 28 tools.

Public MCP servers exist for Yandex Tracker, Yandex Cloud and Yandex Search. None covered Disk, Telemost or Messenger, so this fills that gap — it lets an assistant read and write files on Disk, spin up a Telemost meeting link, and post into a Messenger chat.

Tools

Disk — disk_info, disk_list, disk_find, disk_last_uploaded, disk_download_url, disk_read_text, disk_save_to_local, disk_upload_text, disk_upload_file, disk_mkdir, disk_move, disk_copy, disk_publish, disk_unpublish, disk_delete, disk_public_list

Telemost — telemost_create, telemost_get, telemost_update, telemost_delete, telemost_org_settings

Messenger — messenger_send_text, messenger_send_file, messenger_create_chat, messenger_update_members, messenger_updates, messenger_delete_message

Escape hatch — yandex_api_request calls any documented endpoint that has no dedicated tool yet (reactions, polls, stickers), so you are not blocked waiting on a release.

Install

git clone https://github.com/<you>/mcp-yandex360.git
cd mcp-yandex360
python3 -m venv .venv && ./.venv/bin/pip install -r requirements.txt

Register with Claude Code:

claude mcp add yandex360 --scope user \
  -e YANDEX_DISK_TOKEN=... \
  -e YANDEX_TELEMOST_TOKEN=... \
  -e YANDEX_MESSENGER_BOT_TOKEN=... \
  -- "$PWD/.venv/bin/python" "$PWD/server.py"

Any MCP client works; the server speaks JSON-RPC over stdio.

Configuration

Each token is independent and optional. Tools for an unconfigured service are still registered but fail with a message naming the variable to set, so the server stays healthy while you roll credentials out one service at a time.

One OAuth app at https://oauth.yandex.ru/client/new can carry both the Disk and Telemost scopes. The Messenger bot token comes from the Yandex 360 admin panel under Messenger → Bots.

Safety

Deletes are off unless you set YANDEX_ALLOW_DELETE=1 — write access alone is not enough. disk_publish is treated as a write, not a read, because it mints a link anyone can open.

Notes and limits

• Telemost and Messenger need a Yandex 360 organization account. Neither works with a personal Yandex account.

• A Messenger bot can only post in chats it belongs to, and cannot DM users who disallow it in their privacy settings.

• Disk has no server-side name search. disk_find pages the flat file list and filters locally, so narrow it with media_type on a large Disk.

• Download links returned by the Disk API expire within minutes.
