How do I install the instant meshes mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

It reads `PYTHONUNBUFFERED`, `BLENDER_PATH` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

Instant Meshes MCP Server

本项目用于通过MCP协议提供3D模型处理服务，基于Instant Meshes和pymeshlab对3D模型（OBJ/GLB）进行自动重拓扑、减面和质量分析，支持批量处理、URL输入、材质贴图保留、归档管理等功能。

Recorded tools

Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.

Tool	What it does
input_model	输入模型路径（支持GLB/OBJ文件、文件夹或URL）
target_faces	目标面数
operation	操作类型
auto	自动选择（水密模型用simplify，有问题的用remesh）
simplify	纯减面，保持原有网格结构
remesh	重拓扑，修复网格问题
mode	重拓扑模式（balanced/fine/coarse/fix_holes）
preserve_boundaries	是否保持边界特征
preserve_uv	是否保持UV坐标
create_archive	是否创建归档文件夹（默认true）
quality	网格质量分析（面数、拓扑、建议等）
folder	OBJ文件夹结构分析
validation	OBJ包完整性验证
full	执行所有可用分析
