# mcp-3D-printer-server — 3D Printer MCP Bridge

> mcp-3D-printer-server is an MCP server that inspects models, slices STL/3MF to G-code, and drives printers via OctoPrint/Klipper/Bambu APIs.

## Install

Merge the JSON below into your `.mcp.json`:

## Quick Use

```bash
npm install -g mcp-3d-printer-server
# Configure env vars (printer host/type/API key) then run:
mcp-3d-printer-server
```

## Intro

mcp-3D-printer-server is an MCP server that inspects models, slices STL/3MF to G-code, and drives printers via OctoPrint/Klipper/Bambu APIs.

**Best for:** Makers who want agents to automate slicing, diagnostics, and printer control

**Works with:** Node.js 18+, supported printer APIs (OctoPrint/Klipper/Bambu), optional slicers

**Setup time:** 10-25 minutes

### Key facts (verified)

- GitHub: 186 stars · 41 forks · pushed 2026-05-13.
- License: GPL-2.0 · owner avatar + repo URL verified via GitHub API.
- README-verified entrypoint: `npm install -g mcp-3d-printer-server`.

## Main

- Treat it as an agent-facing control plane: expose safe tools like temperature setting, file inspection, slicing, and printing behind a single MCP server.

- Start with read-only diagnostics and model inspection; enable slicing and print actions only after you’ve validated printer settings and permissions.

- If you containerize, follow the README notes about slicers: host-installed slicers may not work inside Docker unless installed in the image.

### Source-backed notes

- README lists capabilities including STL manipulation/analysis, slicing to G-code, and printer control across multiple printer types.
- README install section shows `npm install -g mcp-3d-printer-server` and a from-source flow using `npm link`.
- README includes Docker instructions and explains slicer limitations in containerized setups.

### FAQ

- **Which printer types are supported?**: README lists multiple backends (OctoPrint/Klipper/Bambu and more); confirm via config options.
- **Can it run without a slicer?**: Some tools are inspection/control; slicing tools require a slicer configured via env vars.
- **How do I avoid unsafe prints?**: Keep destructive tools behind explicit confirmations in your agent prompt and validate env config before enabling print calls.

# Configure env vars (printer host/type/API key) then run:
mcp-3d-printer-server
```

## Intro

mcp-3D-printer-server 是 3D 打印 MCP 服务器：让 agent 读/改 STL/3MF、切片生成 G-code，并通过 OctoPrint/Klipper/Bambu 等 API 直接发起打印。

**Best for:** 想让 agent 参与切片、诊断与打印控制的 3D 打印玩家/实验室

**Works with:** Node.js 18+；OctoPrint/Klipper/Bambu 等打印 API；可选切片器

**Setup time:** 10-25 minutes

### Key facts (verified)

- GitHub：186 stars · 41 forks；最近更新 2026-05-13。
- 许可证：GPL-2.0；作者头像与仓库链接均已通过 GitHub API 复核。
- README 中核对过的入口命令：`npm install -g mcp-3d-printer-server`。

## Main

- 把它当作 agent 的“打印控制平面”：通过一个 MCP server 暴露温度、模型检查、切片、打印等工具。

- 建议先做只读诊断与模型检查；确认打印机权限与配置无误后，再放开切片与打印动作。

- 容器化时注意 README 的提醒：宿主机切片器未必能直接在 Docker 里用，通常要把切片器装进镜像。

### Source-backed notes

- README 列出功能：STL 修改/分析、切片生成 G-code，以及多种打印机类型的控制。
- README 的安装章节给出 `npm install -g mcp-3d-printer-server`，也提供源码安装并用 `npm link` 暴露命令。
- README 给出 Docker 使用方式，并解释容器环境下切片器的限制与建议做法。

### FAQ

- **支持哪些打印机？**：README 列出多种后端（OctoPrint/Klipper/Bambu 等）；具体以配置选项为准。
- **不装切片器能用吗？**：检查/控制类工具可用；涉及切片的工具需要配置切片器路径/类型。
- **怎么避免误打印？**：在 agent 提示词里把高风险工具放到显式确认后再调用，并在启用打印前先验证环境变量配置。
