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。
Instant Meshes MCP MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. 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。.
Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.
Once Instant Meshes MCP is connected, these are the calls the assistant has available:
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You will need 2 environment variables: PYTHONUNBUFFERED, BLENDER_PATH. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Instant Meshes MCP's toolset — input_model, target_faces, operation and 11 more — is a fair guide to whether it matches your workflow. It is maintained by lxy2109; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
| 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 |
