📦 安装
方式一:使用 uvx 直接运行(推荐)
无需安装,直接运行:
uvx --from git+https://github.com/IronManCantFix/image-mcp.git image-mcp方式二:使用 pip 安装
pip install git+https://github.com/IronManCantFix/image-mcp.git安装后可直接使用 image-mcp 命令。
方式三:从源码安装
git clone https://github.com/IronManCantFix/image-mcp.git
cd image-mcp
pip install .⚙️ 配置
Agnes AI(推荐)
export IMAGE_API_URL="https://apihub.agnes-ai.com/v1/images/generations"
export IMAGE_API_KEY="your-agnes-api-key"
export IMAGE_MODEL="agnes-image-2.0-flash"OpenAI
export IMAGE_API_URL="https://api.openai.com/v1/images/generations"
export IMAGE_API_KEY="sk-your-openai-api-key"
export IMAGE_MODEL="gpt-image-2"配置文件
也可以使用配置文件(默认路径 ~/.config/image-mcp/config.json):
{
"api_url": "https://api.openai.com/v1/images/generations",
"api_key": "sk-your-api-key",
"model": "gpt-image-2"
}💡 提示:配置文件路径可通过
IMAGE_CONFIG_PATH环境变量覆盖。
代理配置
如需通过 HTTP 代理访问 API,可设置 IMAGE_PROXY 环境变量或在配置文件中添加 proxy 字段:
export IMAGE_PROXY="http://127.0.0.1:7890"配置文件方式:
{
"api_url": "https://api.openai.com/v1/images/generations",
"api_key": "sk-your-api-key",
"model": "gpt-image-2",
"proxy": "http://127.0.0.1:7890"
}未配置时默认不使用代理,同时也会尊重系统环境变量 HTTP_PROXY / HTTPS_PROXY。
