Environment Variables Configuration

🎯 Global Configuration

Code Context supports a global configuration file at ~/.codecontext/.env to simplify MCP setup across different MCP clients.

Benefits:

  • Configure once, use everywhere
  • No need to specify environment variables in each MCP client
  • Cleaner MCP configurations

📋 Environment Variable Priority

  1. Process Environment Variables (highest)
  2. Global Configuration File (~/.codecontext/.env)
  3. Default Values (lowest)

🔧 Required Environment Variables

Embedding Provider

Variable Description Default
EMBEDDING_PROVIDER Provider: OpenAI, VoyageAI, Gemini, Ollama OpenAI
OPENAI_API_KEY OpenAI API key Required for OpenAI
VOYAGEAI_API_KEY VoyageAI API key Required for VoyageAI
GEMINI_API_KEY Gemini API key Required for Gemini

Vector Database

Variable Description Default
MILVUS_TOKEN Milvus authentication token. Get Zilliz Personal API Key Recommended
MILVUS_ADDRESS Milvus server address. Optional when using Zilliz Personal API Key Auto-resolved from token

Ollama (Local)

Variable Description Default
OLLAMA_HOST Ollama server URL http://127.0.0.1:11434
OLLAMA_MODEL Model name nomic-embed-text

Advanced Configuration

Variable Description Default
EMBEDDING_BATCH_SIZE Batch size for processing. Larger batch size means less indexing time 100
SPLITTER_TYPE Code splitter type: ast, langchain ast
CUSTOM_EXTENSIONS Additional file extensions to include (comma-separated, e.g., .vue,.svelte,.astro) None
CUSTOM_IGNORE_PATTERNS Additional ignore patterns (comma-separated, e.g., temp/**,*.backup,private/**) None

🚀 Quick Setup

1. Create Global Config

mkdir -p ~/.codecontext
cat > ~/.codecontext/.env << 'EOF'
EMBEDDING_PROVIDER=OpenAI
OPENAI_API_KEY=sk-your-openai-api-key
MILVUS_TOKEN=your-zilliz-cloud-api-key
EOF

2. Simplified MCP Configuration

Claude Code:

claude mcp add claude-context -- npx @zilliz/claude-context-mcp@latest

Cursor/Windsurf/Others:

{
  "mcpServers": {
    "claude-context": {
      "command": "npx",
      "args": ["-y", "@zilliz/claude-context-mcp@latest"]
    }
  }
}
