Flux Schnell MCP Server

一个基于MCP(Model Context Protocol)的服务器,用于通过Replicate API调用Flux Schnell模型生成图片。

功能特点

  • 提供generate_image工具用于生成图片
  • 支持自定义文本提示词
  • 自动处理与Replicate API的通信
  • 完整的错误处理和响应

前置要求

  1. Node.js (v14或更高版本)
  2. Replicate API Token
  3. MCP兼容的环境(如Claude Desktop)

获取Replicate API Token

  1. 访问 Replicate官网 并注册账号
  2. 登录后访问 API Tokens页面
  3. 点击"Create API token"创建新的token
  4. 复制生成的token(格式如:r8_xxxxxx)

安装

  1. 克隆项目并安装依赖:
git clone [repository-url]
cd flux-schnell-mcp
npm install
  1. 构建服务器:
npm run build

配置

Claude Desktop配置

  1. 打开配置文件:

    • MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json
    • Windows: %APPDATA%/Claude/claude_desktop_config.json
  2. 添加服务器配置:

{
  "mcpServers": {
    "flux-schnell": {
      "command": "node",
      "args": ["/path/to/flux-schnell-mcp/build/index.js"],
      "env": {
        "REPLICATE_API_TOKEN": "your-replicate-api-token"
      },
      "disabled": false,
      "alwaysAllow": []
    }
  }
}

VSCode Roo配置

  1. 打开配置文件:

    • Linux: ~/.vscode-remote/data/User/globalStorage/rooveterinaryinc.roo-cline/settings/cline_mcp_settings.json
    • MacOS: ~/Library/Application Support/Code/User/globalStorage/rooveterinaryinc.roo-cline/settings/cline_mcp_settings.json
    • Windows: %APPDATA%/Code/User/globalStorage/rooveterinaryinc.roo-cline/settings/cline_mcp_settings.json
  2. 添加与上述相同的服务器配置。

使用方法

服务器提供了一个名为generate_image的工具,可以通过MCP调用:

<use_mcp_tool>
<server_name>flux-schnell</server_name>
<tool_name>generate_image</tool_name>
<arguments>
{
  "prompt": "a beautiful sunset over the ocean, digital art style"
}
</arguments>
</use_mcp_tool>

参数说明

  • prompt: 用于生成图片的文本描述(必填)
    • 建议使用详细的描述来获得更好的生成结果
    • 可以包含风格、场景、细节等信息

响应格式

服务器将返回Replicate API的完整响应,包含生成的图片URL和其他元数据。

调试

由于MCP服务器通过stdio通信,调试可能比较困难。推荐使用MCP Inspector

npm run inspector

Inspector将提供一个URL,可以在浏览器中访问调试工具。

注意事项

  1. 请妥善保管您的Replicate API Token,不要将其分享给他人
  2. 确保在配置文件中使用正确的文件路径
  3. 生成图片可能需要一些时间,请耐心等待响应
  4. 如遇到错误,请检查API Token是否正确,以及网络连接是否正常
