Zen MCP Server

# Zen MCP Server Environment Configuration # Copy this file to .env and fill in your values # API Keys - At least one is required # # IMPORTANT: Choose ONE approach: # - Native APIs (Gemini/OpenAI/XAI) for direct access # - DIAL for unified enterprise access # - OpenRouter for unified cloud access # Having multiple unified providers creates ambiguity about which serves each model. # # Option 1: Use native APIs (recommended for direct access) # Get your Gemini API key from: https://makersuite.google.com/app/apikey GEMINI_API_KEY=your_gemini_api_key_here # Get your OpenAI API key from: https://platform.openai.com/api-keys OPENAI_API_KEY=your_openai_api_key_here # Get your X.AI API key from: https://console.x.ai/ XAI_API_KEY=your_xai_api_key_here # Get your DIAL API key and configure host URL # DIAL provides unified access to multiple AI models through a single API DIAL_API_KEY=your_dial_api_key_here # DIAL_API_HOST=https://core.dialx.ai # Optional: Base URL without /openai suffix (auto-appended) # DIAL_API_VERSION=2025-01-01-preview # Optional: API version header for DIAL requests # Option 2: Use OpenRouter for access to multiple models through one API # Get your OpenRouter API key from: https://openrouter.ai/ # If using OpenRouter, comment out the native API keys above OPENROUTER_API_KEY=your_openrouter_api_key_here # Option 3: Use custom API endpoints for local models (Ollama, vLLM, LM Studio, etc.) # CUSTOM_API_URL=http://localhost:11434/v1 # Ollama example # CUSTOM_API_KEY= # Empty for Ollama (no auth needed) # CUSTOM_MODEL_NAME=llama3.2 # Default model name # Optional: Default model to use # Options: 'auto' (Claude picks best model), 'pro', 'flash', 'o3', 'o3-mini', 'o4-mini', 'o4-mini-high', # 'gpt-5', 'gpt-5-mini', 'grok', 'opus-4.1', 'sonnet-4.1', or any DIAL model if DIAL is configured # When set to 'auto', Claude will select the best model for each task # Defaults to 'auto' if not specified DEFAULT_MODEL=auto # Optional: Default thinking mode for ThinkDeep tool # NOTE: Only applies to models that support extended thinking (e.g., Gemini 2.5 Pro, GPT-5 models) # Flash models (2.0) will use system prompt engineering instead # Token consumption per mode: # minimal: 128 tokens -
