Dify MCP Server

English | 中文

A TypeScript-based MCP (Model Context Protocol) server that connects the MCP Client to Dify applications. This server dynamically exposes Dify applications as tools that can be used directly within the MCP Client.

Overview

This server implements the Model Context Protocol to bridge between MCP Client and Dify applications. It dynamically fetches application specifications from Dify APIs and exposes them as MCP tools. The server allows users to interact with multiple Dify applications through a unified interface within the MCP Client.

Features

Dynamic Dify Integration

• Connects to multiple Dify applications using API keys
• Automatically fetches application metadata and parameters
• Dynamically generates tool interfaces based on Dify application specifications
• Supports various input types including text, paragraphs, and select dropdowns

Request Handling

• Robust error handling with request retries
• Support for both blocking and streaming response modes
• JSON BigInt handling for large numeric values

Configuration

• API keys configured through environment variables
• Configurable base URL and timeout settings
• Fallback to default values when environment variables are not available

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

Integration with Windsurf IDE

To use with Windsurf IDE, add the server config 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"
      }
    }
  }
}

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 Environment Variables

API密钥(AGENT_API_KEYS)： 多个以,分割

Usage

Once configured, the Dify MCP Server will:

1. Connect to the specified Dify applications using the provided API keys
2. Fetch application metadata and parameter specifications
3. Generate MCP tool interfaces based on the Dify application configurations
4. Make these tools available within the Windsurf IDE

Each Dify application will be exposed as a separate tool with a name format of dify_app_info_{application_name}.
