SD + TTS MCP Server
Exposes Stable Diffusion for text-to-image generation and GPT-SoVITS for text-to-speech synthesis as MCP tools, enabling image and audio generation via natural language.
README
SD + TTS MCP Server
A Model Context Protocol (MCP) server exposing Stable Diffusion (txt2img) and GPT-SoVITS (TTS) as standard MCP tools, for use with any MCP-compatible client (Codex, Claude Desktop, etc.).
Quick Start
# 1. Install
git clone https://github.com/yyboling-commits/mcp-sd-tts-server.git
cd mcp-sd-tts-server
pip install mcp requests pyyaml
# 2. Configure
cp config.example.yaml config.yaml
# Edit config.yaml with your service URLs
# 3. Run
python src/server.py
Configuration
Copy config.example.yaml to config.yaml and edit:
sd:
url: "http://127.0.0.1:7860" # SD WebUI 地址
default_model: "" # 默认模型名(可选)
tts:
url: "http://127.0.0.1:9880" # GPT-SoVITS 地址
default_voice: "" # 默认音色(可选)
server:
name: "sd-tts-mcp"
transport: "stdio" # stdio | sse
前置条件
- Stable Diffusion WebUI 需启动并开启
--api参数 - GPT-SoVITS TTS 需启动 API 服务(默认端口 9880)
Transport 模式
stdio 模式(默认,推荐)
python src/server.py
标准输入输出模式,适用于 MCP 客户端直接启动子进程调用。
SSE 模式(HTTP)
python src/server.py --transport sse
HTTP 服务模式,监听 0.0.0.0:8000。SSE 端点 /sse,消息端点 /messages。
注册到客户端
Codex / Claude Desktop
在 MCP 配置中添加:
{
"mcpServers": {
"sd-tts": {
"command": "python",
"args": ["路径/src/server.py"],
"env": {}
}
}
}
其他 MCP 客户端
任意支持 stdio transport 的 MCP 客户端均可使用,配置方式同上。
