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
- Node.js (v14或更高版本)
- Replicate API Token
- MCP兼容的环境(如Claude Desktop)
获取Replicate API Token
- 访问 Replicate官网 并注册账号
- 登录后访问 API Tokens页面
- 点击"Create API token"创建新的token
- 复制生成的token(格式如:r8_xxxxxx)
安装
- 克隆项目并安装依赖:
git clone [repository-url]
cd flux-schnell-mcp
npm install
- 构建服务器:
npm run build
配置
Claude Desktop配置
-
打开配置文件:
- MacOS:
~/Library/Application Support/Claude/claude_desktop_config.json
- Windows:
%APPDATA%/Claude/claude_desktop_config.json
- MacOS:
-
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
-
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
- Linux:
-
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
- 请妥善保管您的Replicate API Token,不要将其分享给他人
- 确保在配置文件中使用正确的文件路径
- 生成图片可能需要一些时间,请耐心等待响应
- 如遇到错误,请检查API Token是否正确,以及网络连接是否正常
