Dify MCP server

Dify MCP Server is a powerful bridge that connects MCP Client to Dify applications. It dynamically exposes Dify applications as tools that can be used directly within MCP Client, allowing users to interact with multiple Dify applications through a unified interface.

Installation

Prerequisites

• Node.js (v16 or higher)
• npm or yarn

Setup

1. Clone the repository:

git clone https://github.com/zhuzhoulin/dify-mcp-server.git
cd dify-mcp-server

2. Install dependencies:

npm install

3. Build the project:

npm run build

Configuration

Environment Variables

The server uses the following environment variables:

• AGENT_API_KEYS: Comma-separated list of Dify API keys
• BASE_URL: Base URL for Dify API (default: https://api.dify.ai)
• TIMEOUT: Request timeout in milliseconds (default: 60000)

How to Get API Keys

To obtain the necessary API keys for the AGENT_API_KEYS environment variable:

1. Log into your Dify account
2. Navigate to your application settings
3. Locate and copy your API keys
4. For multiple applications, separate each key with a comma

Integration with Windsurf IDE

To use the server with Windsurf IDE, add this configuration to your MCP settings:

{
  "mcpServers": {
    "dify-mcp-server": {
      "command": "node",
      "args": [
        "/path/to/dify-mcp-server/build/index.js"
      ],
      "env": {
        "AGENT_API_KEYS": "key1,key2,key3",
        "BASE_URL": "https://api.dify.ai",
        "TIMEOUT": "60000"
      }
    }
  }
}

Usage

Once properly configured, the Dify MCP Server automatically:

1. Connects to specified Dify applications using the provided API keys
2. Fetches application metadata and parameter specifications
3. Generates MCP tool interfaces based on the Dify application configurations
4. Makes these tools available within the Windsurf IDE

Accessing Tools

Each Dify application is exposed as a separate tool with a naming format of dify_app_info_{application_name}. You can access these tools directly through the MCP Client interface.

Features

The server supports:

• Multiple Dify Applications: Connect to various Dify applications simultaneously
• Dynamic Tool Generation: Automatically creates tool interfaces based on application specifications
• Various Input Types: Supports text, paragraphs, and select dropdowns
• Response Modes: Works with both blocking and streaming response modes

Troubleshooting

If you encounter issues:

1. Verify your API keys are correct and have the necessary permissions
2. Check that the BASE_URL is accessible from your environment
3. Review server logs for detailed error messages
4. Ensure the Dify applications are properly configured and accessible

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "dify-mcp-server" '{"command":"node","args":["/path/to/dify-mcp-server/build/index.js"],"env":{"AGENT_API_KEYS":"key1,key2,key3","BASE_URL":"https://api.dify.ai","TIMEOUT":"60000"}}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "dify-mcp-server": {
            "command": "node",
            "args": [
                "/path/to/dify-mcp-server/build/index.js"
            ],
            "env": {
                "AGENT_API_KEYS": "key1,key2,key3",
                "BASE_URL": "https://api.dify.ai",
                "TIMEOUT": "60000"
            }
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "dify-mcp-server": {
            "command": "node",
            "args": [
                "/path/to/dify-mcp-server/build/index.js"
            ],
            "env": {
                "AGENT_API_KEYS": "key1,key2,key3",
                "BASE_URL": "https://api.dify.ai",
                "TIMEOUT": "60000"
            }
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
