MCP Client Configuration

Installing extension in Claude Desktop

Yandex Tracker MCP Server can be one-click installed in Claude Desktop as and extension.

Installation

1. Download the *.mcpb file from GitHub Releases.
2. Double-click the downloaded file to install it in Claude Desktop.
3. Provide your Yandex Tracker OAuth token when prompted.
4. Make sure extension is enabled - now you may use this MCP Server.

Manual installation

Prerequisites

• uv installed globally
• Valid Yandex Tracker API token with appropriate permissions

The following sections show how to configure the MCP server for different AI clients. You can use either uvx yandex-tracker-mcp@latest or the Docker image ghcr.io/aikts/yandex-tracker-mcp:latest. Both require these environment variables:

• Authentication (one of the following):
  • TRACKER_TOKEN - Your Yandex Tracker OAuth token
  • TRACKER_IAM_TOKEN - Your IAM token
  • TRACKER_SA_KEY_ID, TRACKER_SA_SERVICE_ACCOUNT_ID, TRACKER_SA_PRIVATE_KEY - Service account credentials
• TRACKER_CLOUD_ORG_ID or TRACKER_ORG_ID - Your Yandex Cloud (or Yandex 360) organization ID

Important Notes:

• Replace placeholder values with your actual credentials
• Restart your AI client after configuration changes
• Ensure uvx is installed and available in your system PATH
• For production use, consider using environment variables instead of hardcoding tokens

Available MCP Tools

The server exposes the following tools through the MCP protocol:

http Transport

The MCP server can also be run in streamable-http mode for web-based integrations or when stdio transport is not suitable.

streamable-http Mode Environment Variables

# Required - Set transport to streamable-http mode
TRANSPORT=streamable-http

# Server Configuration
HOST=0.0.0.0  # Default: 0.0.0.0 (all interfaces)
PORT=8000     # Default: 8000

Starting the streamable-http Server

# Basic streamable-http server startup
TRANSPORT=streamable-http uvx yandex-tracker-mcp@latest

# With custom host and port
TRANSPORT=streamable-http \
HOST=localhost \
PORT=9000 \
uvx yandex-tracker-mcp@latest

# With all environment variables
TRANSPORT=streamable-http \
HOST=0.0.0.0 \
PORT=8000 \
TRACKER_TOKEN=your_token \
TRACKER_CLOUD_ORG_ID=your_org_id \
uvx yandex-tracker-mcp@latest

You may skip configuring TRACKER_CLOUD_ORG_ID or TRACKER_ORG_ID if you are using the following format when connecting to MCP Server (example for Claude Code):

claude mcp add --transport http yandex-tracker "http://localhost:8000/mcp/?cloudOrgId=your_cloud_org_id&"

or

claude mcp add --transport http yandex-tracker "http://localhost:8000/mcp/?orgId=org_id&"

You may also skip configuring global TRACKER_TOKEN environment variable if you choose to use OAuth 2.0 authentication (see below).

OAuth 2.0 Authentication

The Yandex Tracker MCP Server supports OAuth 2.0 authentication as a secure alternative to static API tokens. When configured, the server acts as an OAuth provider, facilitating authentication between your MCP client and Yandex OAuth services.

How OAuth Works

The MCP server implements a standard OAuth 2.0 authorization code flow:

1. Client Registration: Your MCP client registers with the server to obtain client credentials
2. Authorization: Users are redirected to Yandex OAuth to authenticate
3. Token Exchange: The server exchanges authorization codes for access tokens
4. API Access: Clients use bearer tokens for all API requests
5. Token Refresh: Expired tokens can be refreshed without re-authentication

MCP Client → MCP Server → Yandex OAuth → User Authentication
    ↑                                           ↓
    └────────── Access Token ←─────────────────┘

OAuth Configuration

To enable OAuth authentication, set the following environment variables:

# Enable OAuth mode
OAUTH_ENABLED=true

# Yandex OAuth Application Credentials (required for OAuth)
OAUTH_CLIENT_ID=your_yandex_oauth_app_id
OAUTH_CLIENT_SECRET=your_yandex_oauth_app_secret

# Public URL of your MCP server (required for OAuth callbacks)
MCP_SERVER_PUBLIC_URL=https://your-mcp-server.example.com

# Optional OAuth settings
OAUTH_SERVER_URL=https://oauth.yandex.ru  # Default Yandex OAuth server

# When OAuth is enabled, TRACKER_TOKEN becomes optional

Setting Up Yandex OAuth Application

1. Go to Yandex OAuth and create a new application
2. Set the callback URL to: {MCP_SERVER_PUBLIC_URL}/oauth/yandex/callback
3. Request the following permissions:
   • tracker:read - Read permissions for Tracker
   • tracker:write - Write permissions for Tracker
4. Save your Client ID and Client Secret

OAuth vs Static Token Authentication

OAuth Mode Limitations

• Currently, the OAuth mode requires the MCP server to be publicly accessible for callback URLs
• OAuth mode is best suited for interactive clients that support web-based authentication flows

Using OAuth with MCP Clients

When OAuth is enabled, MCP clients will need to:

1. Support OAuth 2.0 authorization code flow
2. Handle token refresh when access tokens expire
3. Store refresh tokens securely for persistent authentication

Note: Not all MCP clients currently support OAuth authentication. Check your client’s documentation for OAuth compatibility.

Example configuration for Claude Code:

claude mcp add --transport http yandex-tracker https://your-mcp-server.example.com/mcp/ -s user

OAuth Data Storage

The MCP server supports two different storage backends for OAuth data (client registrations, access tokens, refresh tokens, and authorization states):

InMemory Store (Default)

The in-memory store keeps all OAuth data in server memory. This is the default option and requires no additional configuration.

Characteristics:

• Persistence: Data is lost when the server restarts
• Performance: Very fast access since data is stored in memory
• Scalability: Limited to single server instance
• Setup: No additional dependencies required
• Best for: Development, testing, or single-instance deployments where losing OAuth sessions on restart is acceptable

Configuration:

OAUTH_STORE=memory  # Default value, can be omitted

Redis Store

The Redis store provides persistent storage for OAuth data using a Redis database. This ensures OAuth sessions survive server restarts and enables multi-instance deployments.

Characteristics:

• Persistence: Data persists across server restarts
• Performance: Fast access with network overhead
• Scalability: Supports multiple server instances sharing the same Redis database
• Setup: Requires Redis server installation and configuration
• Best for: Production deployments, high availability setups, or when OAuth sessions must persist

Configuration:

# Enable Redis store for OAuth data
OAUTH_STORE=redis

# Redis connection settings (same as used for tools caching)
REDIS_ENDPOINT=localhost                  # Default: localhost
REDIS_PORT=6379                           # Default: 6379
REDIS_DB=0                                # Default: 0
REDIS_PASSWORD=your_redis_password        # Optional: Redis password
REDIS_POOL_MAX_SIZE=10                    # Default: 10

Storage Behavior:

• Client Information: Stored persistently
• OAuth States: Stored with TTL (time-to-live) for security
• Authorization Codes: Stored with TTL and automatically cleaned up after use
• Access Tokens: Stored with automatic expiration based on token lifetime
• Refresh Tokens: Stored persistently until revoked
• Key Namespacing: Uses oauth:* prefixes to avoid conflicts with other Redis data

Token Encryption (Required for Redis Store)

When using Redis store, you must configure encryption to protect OAuth tokens at rest. Token values are encrypted using Fernet (AES-128) and Redis keys use SHA-256 hashes instead of raw tokens, preventing token exposure if Redis is compromised.

Generate an encryption key:

python3 -c "import base64, os; print(base64.b64encode(os.urandom(32)).decode())"

Configuration:

# Single encryption key
OAUTH_ENCRYPTION_KEYS=

# Multiple keys for rotation (first encrypts, all decrypt)
OAUTH_ENCRYPTION_KEYS=,

Key rotation allows seamless key updates: add the new key first, wait for old tokens to expire, then remove the old key.

Important Notes:

• Both stores use the same Redis connection settings as the tools caching system
• When using Redis store, ensure your Redis instance is properly secured and accessible
• The OAUTH_STORE setting only affects OAuth data storage; tools caching uses TOOLS_CACHE_ENABLED
• Redis store uses JSON serialization for better cross-language compatibility and debugging

Authentication

Yandex Tracker MCP Server supports multiple authentication methods with a clear priority order. The server will use the first available authentication method based on this hierarchy:

Authentication Priority Order

1. Dynamic OAuth Token (highest priority)

   • When OAuth is enabled and a user authenticates via OAuth flow
   • Tokens are dynamically obtained and refreshed per user session
   • Supports both standard Yandex OAuth and Yandex Cloud federative OAuth
   • Required env vars: OAUTH_ENABLED=true, OAUTH_CLIENT_ID, OAUTH_CLIENT_SECRET, MCP_SERVER_PUBLIC_URL
   • Additional vars for federative OAuth: OAUTH_SERVER_URL=https://auth.yandex.cloud/oauth, OAUTH_TOKEN_TYPE=Bearer, OAUTH_USE_SCOPES=false

2. Passthrough Bearer OAuth Token

   • When MCP OAuth middleware does not provide a token, the server can read a Yandex OAuth token from the incoming Authorization: Bearer header
   • Useful behind a trusted reverse proxy or gateway that authenticates users, resolves their stored Yandex OAuth token, and injects it per request
   • The token from MCP OAuth still has priority when OAuth mode is enabled and active

3. Static OAuth Token

   • Traditional OAuth token provided via environment variable
   • Single token used for all requests
   • Required env var: TRACKER_TOKEN (your OAuth token)

4. Static IAM Token

   • IAM (Identity and Access Management) token for service-to-service authentication
   • Suitable for automated systems and CI/CD pipelines
   • Required env var: TRACKER_IAM_TOKEN (your IAM token)

5. Dynamic IAM Token (lowest priority)

   • Automatically retrieved using service account credentials
   • Token is fetched and refreshed automatically
   • Required env vars: TRACKER_SA_KEY_ID, TRACKER_SA_SERVICE_ACCOUNT_ID, TRACKER_SA_PRIVATE_KEY

Authentication Scenarios

Scenario 1: OAuth with Dynamic Tokens (Recommended for Interactive Use)

# Enable OAuth mode
OAUTH_ENABLED=true
OAUTH_CLIENT_ID=your_oauth_app_id
OAUTH_CLIENT_SECRET=your_oauth_app_secret
MCP_SERVER_PUBLIC_URL=https://your-server.com

# Organization ID (choose one)
TRACKER_CLOUD_ORG_ID=your_cloud_org_id  # or TRACKER_ORG_ID

Scenario 2: Static OAuth Token (Simple Setup)

# OAuth token
TRACKER_TOKEN=your_oauth_token

# Organization ID (choose one)
TRACKER_CLOUD_ORG_ID=your_cloud_org_id  # or TRACKER_ORG_ID

Scenario 3: Passthrough Bearer Token Behind a Reverse Proxy

Use this mode when a trusted gateway handles user authentication, looks up the user’s Yandex OAuth token, and forwards the request to the MCP server with that token in the request header:

Authorization: Bearer 

# Organization ID (choose one)
TRACKER_CLOUD_ORG_ID=your_cloud_org_id  # or TRACKER_ORG_ID

This passthrough token is used only when MCP OAuth middleware has not provided an access token for the request. In OAuth-enabled deployments with an active MCP OAuth session, the MCP OAuth token takes priority.

Scenario 4: Static IAM Token

# IAM token
TRACKER_IAM_TOKEN=your_iam_token

# Organization ID (choose one)
TRACKER_CLOUD_ORG_ID=your_cloud_org_id  # or TRACKER_ORG_ID

Scenario 5: Dynamic IAM Token with Service Account

# Service account credentials
TRACKER_SA_KEY_ID=your_key_id
TRACKER_SA_SERVICE_ACCOUNT_ID=your_service_account_id
TRACKER_SA_PRIVATE_KEY=your_private_key

# Organization ID (choose one)
TRACKER_CLOUD_ORG_ID=your_cloud_org_id  # or TRACKER_ORG_ID

Scenario 6: Federative OAuth for OIDC Applications (Advanced)

# Enable OAuth with Yandex Cloud federation
OAUTH_ENABLED=true
OAUTH_SERVER_URL=https://auth.yandex.cloud/oauth
OAUTH_TOKEN_TYPE=Bearer
OAUTH_USE_SCOPES=false
OAUTH_CLIENT_ID=your_oidc_client_id
OAUTH_CLIENT_SECRET=your_oidc_client_secret
MCP_SERVER_PUBLIC_URL=https://your-server.com

# Organization ID (choose one)
TRACKER_CLOUD_ORG_ID=your_cloud_org_id  # or TRACKER_ORG_ID

This configuration enables authentication through Yandex Cloud OIDC applications, which is required for federated accounts in Yandex Cloud. Federated users authenticate through their organization’s identity provider (IdP) and use this OAuth flow to access Yandex Tracker APIs.

Important Notes

• The server checks authentication methods in the order listed above
• Only one authentication method will be used at a time
• For production use, dynamic tokens (OAuth or IAM) are recommended for better security
• IAM tokens have a shorter lifetime than OAuth tokens and may need more frequent renewal
• When using service accounts, ensure the account has appropriate permissions for Yandex Tracker

TRACKER_READ_ONLY=true                    # Default: false - Disable all write tools for the whole instance

Queue Access Control

Access to queues can be scoped at three levels, from coarse to fine-grained:

• TRACKER_LIMIT_QUEUES — allow-list of queue keys. Queues outside the list are treated as not found / not allowed for both reads and writes.
• TRACKER_READ_ONLY — when true, all write tools are unregistered, so the whole instance is read-only.
• TRACKER_READ_ONLY_QUEUES — per-queue read-only allow-list. Write tools stay registered, but any mutating call (create/update/move/comment/worklog/link, queue version creation) targeting a listed queue is rejected, while reads keep working. Queues not listed here remain read-write.

This lets a single instance be read-write on some queues and read-only on others at the same time — e.g. TRACKER_LIMIT_QUEUES=DEV,MGMT together with TRACKER_READ_ONLY_QUEUES=MGMT gives full access to DEV and read-only visibility into MGMT. This is especially useful for a shared MCP gateway where end users reach Tracker only through the server and never hold the raw token themselves.

These checks are in-process guardrails. For clients that hold the raw Tracker token directly, real limits should additionally be enforced on the token itself.
