Yandex Tracker MCP

Small stdio MCP server for Yandex Tracker. It exposes tools for reading, searching, creating, updating, commenting on, transitioning, and linking Tracker issues, plus read-only reference lookups (queues, users, statuses, types, priorities, fields, versions, components).

Usage with Codex

Add the server to ~/.codex/config.toml:

[mcp_servers.yandex-tracker]
command = "uvx"
args = ["mcp-yandex-tracker"]

[mcp_servers.yandex-tracker.env]
YANDEX_TRACKER_TOKEN = "..."
YANDEX_TRACKER_CLOUD_ORG_ID = "..."

To run the latest unreleased code straight from source instead, replace the args line with:

args = ["--from", "git+https://github.com/kawaii-snafy/mcp-yandex-tracker.git", "mcp-yandex-tracker"]

For a non-cloud organization, use YANDEX_TRACKER_ORG_ID instead of YANDEX_TRACKER_CLOUD_ORG_ID.

Restart Codex after changing the config. The server exposes tools named tracker_*, such as tracker_get_issue, tracker_search_issues, and tracker_add_comment.

Usage with Claude Code

Add the server with the Claude Code CLI:

claude mcp add --transport stdio \
  --env YANDEX_TRACKER_TOKEN="..." \
  --env YANDEX_TRACKER_CLOUD_ORG_ID="..." \
  yandex-tracker \
  -- uvx mcp-yandex-tracker

For a non-cloud organization, use --env YANDEX_TRACKER_ORG_ID="..." instead of YANDEX_TRACKER_CLOUD_ORG_ID.

Verify the Claude Code registration:

claude mcp list
claude mcp get yandex-tracker

Inside Claude Code, use /mcp to check the server connection and tools.

Environment

Required:

• YANDEX_TRACKER_TOKEN: OAuth or IAM token.
• One organization id: YANDEX_TRACKER_CLOUD_ORG_ID for cloud organizations or YANDEX_TRACKER_ORG_ID for non-cloud organizations.

Optional:

• YANDEX_TRACKER_AUTH_SCHEME: OAuth by default. Use Bearer for IAM tokens.
• YANDEX_TRACKER_BASE_URL: https://api.tracker.yandex.net by default.
• YANDEX_TRACKER_TIMEOUT: 30 by default.

Verify locally

Run the MCP server and ask for its tool list. MCP requires the initialize handshake before any other request, so send it (and the initialized notification) first:

printf '%s\n' \
  '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-11-25","capabilities":{},"clientInfo":{"name":"probe","version":"1"}}}' \
  '{"jsonrpc":"2.0","method":"notifications/initialized"}' \
  '{"jsonrpc":"2.0","id":2,"method":"tools/list"}' \
| YANDEX_TRACKER_TOKEN="..." YANDEX_TRACKER_CLOUD_ORG_ID="..." uvx mcp-yandex-tracker

The second response line should be a JSON-RPC object with tracker_* tools. The server is stdio-only, so stdout is reserved for MCP JSON-RPC messages (logs go to stderr).
