Configuration Methods

​

Method 1: Environment File (.env)

# Copy from .env.example
cp .env.example .env

# Edit with your keys
vim .env

​

Method 2: System Environment Variables

export ANTHROPIC_API_KEY="your-key-here"
export PERPLEXITY_API_KEY="your-key-here"
# ... other keys

​

Method 3: MCP Server Configuration

{
  "mcpServers": {
    "task-master-ai": {
      "command": "npx",
      "args": ["-y", "task-master-ai"],
      "env": {
        "ANTHROPIC_API_KEY": "your-key-here",
        "PERPLEXITY_API_KEY": "your-key-here",
        "OPENAI_API_KEY": "your-key-here"
      }
    }
  }
}

​

Key Requirements

​

Minimum Requirements

• At least one AI provider key is required
• ANTHROPIC_API_KEY is recommended as the primary provider
• PERPLEXITY_API_KEY is highly recommended for research features

​

Provider-Specific Requirements

• Azure OpenAI: Requires both AZURE_OPENAI_API_KEY and AZURE_OPENAI_ENDPOINT configuration
• Google Vertex: Requires VERTEX_PROJECT_ID and VERTEX_LOCATION environment variables
• AWS Bedrock: Uses AWS credential chain (profiles, IAM roles, etc.) instead of API keys
• Ollama: Only needs API key for remote servers with authentication
• CLI Providers: Gemini CLI, Grok CLI, and Claude Code use OAuth/CLI config instead of API keys

​

Model Configuration

# Interactive model setup
task-master models --setup

# Set specific models
task-master models --set-main claude-3-5-sonnet-20241022
task-master models --set-research perplexity-llama-3.1-sonar-large-128k-online
task-master models --set-fallback gpt-4o-mini

​

Security Best Practices

1. Never commit API keys to version control
2. Use .env files and add them to .gitignore
3. Rotate keys regularly especially if compromised
4. Use minimal permissions for service accounts
5. Monitor usage to detect unauthorized access

​

Troubleshooting

​

Key Validation

# Check if keys are properly configured
task-master models

# Test specific provider
task-master add-task --prompt="test task" --model=claude-3-5-sonnet-20241022

​

Common Issues

• Invalid key format: Check the expected format for each provider
• Insufficient permissions: Ensure keys have necessary API access
• Rate limits: Some providers have usage limits
• Regional restrictions: Some models may not be available in all regions
