"""
|
||
基于 mcp_docx.py 封装的 MCP 服务器。
|
||
|
||
暴露两个主要工具:
|
||
- list_docx_images:列出 DOCX 中的图片信息
|
||
- edit_docx: 进行文本替换 / 关键字上色 / 图片替换
|
||
|
||
当前推荐的传输方式:
|
||
- stdio(本地调试)
|
||
- streamable-http(远程 HTTP,路径固定为 /mcp,推荐)
|
||
|
||
用法:
|
||
# 本地 stdio 模式(默认)
|
||
python mcp_docx_server.py --transport stdio
|
||
|
||
# HTTP 远程模式(推荐,默认 0.0.0.0:8080,对外暴露 /mcp)
|
||
python mcp_docx_server.py --transport http
|
||
python mcp_docx_server.py --transport http --host 0.0.0.0 --port 8080
|
||
|
||
# 客户端连接地址(http 模式):
|
||
# MCP 端点: http://<host>:<port>/mcp
|
||
|
||
注意:底层仍然完全复用 mcp_docx.py 中的逻辑,只是通过 MCP SDK 对外提供。
