Access and checks

How we review

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

  • The server reads Yandex mail, calendar and issues and, with write permissions granted, sends mail and edits events and issues
  • Yandex tokens are kept on the computer in the system storage or in environment variables

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

What it does

The Node.js server runs on the user's computer and talks to Yandex directly, with no intermediary. Sign-in is a Sign in with Yandex button in the browser, and tokens go to the system secure storage. The tools cover Tracker (issues, comments, links, attachments, time tracking, sprints and boards), Mail (search, reading without marking as read, drafts, sending, moving) and Calendar (events with recurrence, creating and editing). The plugin adds workflows: standup, Telemost meeting recap with issue creation, meeting prep, weekly report, mail to issue, stale issues, sprint planning and review.

Who it is for. Team leads and developers who track work in Yandex Tracker, use Yandex Mail and Calendar, and work in Claude Code or Claude Desktop.

Good fit when

  • You want a standup or weekly report assembled from Tracker and Calendar
  • After a Telemost meeting you want issues with assignees and due dates created
  • You want emails turned into Tracker issues without duplicates
  • You want control: the agent reads mail and calendar, and writing is switched on by separate permission groups

Not a fit when

  • You use claude.ai in a browser or the mobile app: local servers do not start there
  • Your organization allows only its own OAuth apps, so the shared sign-in will not work without setup
  • You need an official Yandex server: the project is not affiliated with Yandex

1 keeps read-only access regardless of granted permissions

Limitations

The project is unofficial and not affiliated with Yandex. It runs only on the user's computer: Node.js 20 or newer is required, and local servers do not start in browser claude.ai or the mobile apps. Access is read-only by default, with writing, sending and deleting enabled by permission groups. Tracker needs an organization ID. Six stars, one author, last commit in September 2026. Workflow instructions are written in Russian, and Claude replies in the user's language. In Claude Desktop the workflows live in the plus menu; in Claude Code commands carry the ya360 prefix, and workflows without a prefix are installed with a separate command.

How to disable. Set YANDEX_MCP_READONLY=1, then run ya360-mcp logout or remove the plugin with /plugin uninstall ya360, and revoke the app access in Yandex ID.

FAQ

Can the server be limited to reading?

Yes, access is read-only by default, and YANDEX_MCP_READONLY=1 keeps it read-only even if write permissions are granted.

Do I need my own OAuth app?

Usually not, sign-in goes through Sign in with Yandex. Your own app on oauth.yandex.ru is needed if the organization allows only its own.

Where does the server run?

Only on the user's computer, in Claude Code, Claude Desktop and Cowork sessions on that computer.

How many tools does the server have?

Forty-five tools across Tracker, Mail and Calendar, with the full list in the repository wiki.

Which workflows does the plugin add?

Eleven, including standup, meeting recap, meeting prep, weekly report, mail to issue and sprint planning.
