# 基本語法
claude mcp add --transport http <name> <url>

# 實際範例：連接到 Notion
claude mcp add --transport http notion https://mcp.notion.com/mcp

# 使用 Bearer token 的範例
claude mcp add --transport http secure-api https://api.example.com/mcp \
  --header "Authorization: Bearer your-token"

# 基本語法
claude mcp add --transport sse <name> <url>

# 實際範例：連接到 Asana

  --header "X-API-Key: your-key-here"

# 基本語法
claude mcp add [options] <name> -- <command> [args...]

# 實際範例：新增 Airtable server
claude mcp add --transport stdio --env AIRTABLE_API_KEY=YOUR_KEY airtable \
  -- npx -y airtable-mcp-server

# 列出所有已配置的 servers
