Integration with Claude Desktop App

To use with Claude Desktop App, add the following settings to Claude's configuration file:

Windows

Add to %AppData%\Claude\claude_desktop_config.json:

{
  "mcpServers": {
    "dify-workflow": {
      "command": "npx",
      "args": ["@tonlab/dify-mcp-server"],
      "env": {
        "DIFY_BASE_URL": "https://your-dify-endpoint",
        "DIFY_API_KEY": "your-api-key-here"
      }
    }
  }
}

Using Multiple API Keys (NEW)

You can now configure multiple Dify API keys, which will create multiple tools (one per API key):

{
  "mcpServers": {
    "dify": {
      "command": "npx",
      "args": ["@tonlab/dify-mcp-server"],
      "env": {
        "DIFY_BASE_URL": "https://api.dify.ai/v1",
        "DIFY_API_KEYS": "app-FirstAPIKeyHere,app-SecondAPIKeyHere,app-ThirdAPIKeyHere"
      }
    }
  }
}

Each API key will be exposed as a separate tool in Claude, with a distinct number appended to the tool name.

macOS/Linux

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "dify-workflow": {
      "command": "npx",
      "args": ["@tonlab/dify-mcp-server"],
      "env": {
        "DIFY_BASE_URL": "https://your-dify-endpoint",
        "DIFY_API_KEY": "your-api-key-here"
      }
    }
  }
}

Same multiple API key configuration as described above works on macOS/Linux as well.
