Quick Start

Step 1: Get an API Key

Visit unveilchem.com to obtain your ChemFlow API Key.

Step 2: Configure Your AI Client

Option A: Trae (International)

Click this link (replace YOUR_API_KEY with your actual key):

trae://trae.ai-ide/mcp-import?type=http&name=chemflow&config=<base64_encoded_config>

Or manually add in Trae IDE → Settings → MCP → Add → Manual:

{
  "mcpServers": {
    "chemflow": {
      "url": "https://unveilchem.com/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Option B: Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "chemflow": {
      "url": "https://unveilchem.com/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Option C: Cursor / Windsurf / Other MCP Clients

{
  "mcpServers": {
    "chemflow": {
      "url": "https://unveilchem.com/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Step 3: Verify Connection

Ask your AI assistant: "List available ChemFlow tools"

You should see 12 tools listed.
