CAD查询MCP服务器
一种模型上下文协议(MCP)服务器,为克劳德代码提供CAD生成和验证工具。该服务器通过MCP工具公开CAD查询功能,实现对话式3D建模。
特性
verify_cad_query-根据条件验证CAD查询生成的模型generate_cad_query- _(Stub实施)_ 根据描述生成CAD查询Python脚本- CAD查询集成 -参数化三维建模的完整CAD查询支持
- STL/STEP导出 -直接导出为3D打印和CAD格式
- 视觉反馈 -用于模型检查的SVG生成
安装
# Install dependencies
uv sync
# For development with CAD verification capabilities
uv sync --extra cad
# Test the server
uv run python tests/test_server.py
# Run with MCP Inspector (interactive testing)
uv run mcp dev server.pyClaude桌面配置

}MCP工具
verify_cad_query
根据指定条件验证CAD查询生成的模型。
参数:
file_path(string):CAD查询Python文件的路径verification_criteria(string):验证内容的描述
例子:
{
"file_path": "models/coffee_mug.py",
"verification_criteria": "coffee mug with handle, 10cm height, 8cm diameter"
}退货:
{
"status": "PASS" | "FAIL",
"message": "Description of result",
"file_path": "Path to verified file",
"criteria": "Verification criteria used",
"details": "Additional verification details"
}generate_cad_query _(Stub实施)_
从自然语言描述生成CAD查询Python脚本。
备注:当前返回一个存根响应,表示该功能尚未实现。
参数:
description(string):所需3D模型的自然语言描述parameters(字符串,可选):特定尺寸或约束
例子:
{
"description": "Create a coffee mug with a handle, 10cm tall and 8cm diameter",
"parameters": "height=100mm, diameter=80mm, handle_width=15mm"
}退货:
{
"status": "NOT_IMPLEMENTED",
"message": "CAD code generation is not yet implemented",
"description": "Input description",
"parameters": "Input parameters",
"details": "Additional information"
}CAD查询脚本要求
所有CAD查询脚本必须以结尾 show_object(result):
import cadquery as cq
result = cq.Workplane("XY").box(10, 10, 10)
show_object(result) # Required for processing发展
测试
# Test server functionality
uv run python tests/test_server.py
# Interactive testing with MCP Inspector
uv run mcp dev server.py
# Run evaluations
uv run python evaluations/evaluate_verify.py扩展服务器
电流 verify_cad_query 实现是一个基本的验证器。您可以将其增强为:
- 解析和验证CAD查询语法
- 执行模型生成并捕获错误
- 分析生成的几何尺寸
- 检查特定功能和约束
- 生成详细的验证报告
