[!IMPORTANT] Saved scenes, not realtime GUI control. KeyShot MCP runs headless on the same computer as KeyShot. It does not read unsaved edits or control the open KeyShot window. 处理已保存的场景，不是实时 GUI 控制。 服务在本机后台运行 KeyShot，不能读取窗口中尚未保存的修改。

Client Agent and privacy. The Agent in your MCP client receives scene information and previews returned by tools. Depending on the client's implementation and settings, these results may be sent to its configured model provider. KeyShot MCP itself does not upload them. Review privacy and security before confidential work.

客户端 Agent 与隐私。 MCP 客户端中的 Agent 会接收工具返回的场景信息和预览； 这些内容可能根据客户端的实现与配置发送给其所选模型服务。KeyShot MCP 本身不主动上传这些内容。 保密项目请先阅读隐私与安全说明。

From a Request to a Render / 一句话到出图

After setup, describe the change to your Agent. It uses KeyShot MCP to perform the work on a saved scene copy; you review the preview before final output. 完成安装后，直接向 Agent 描述需求。它通过 KeyShot MCP 处理已保存场景的副本， 你看过预览、确认效果后，再正式出图。

“Change the lantern's metal to brushed steel, keep the glass unchanged, and show me a preview. Once I approve, export the image and a scene copy.”

“把灯具的金属换成拉丝钢，玻璃保持不变，先给我看预览。确认后输出图片和场景副本。”

Not happy with the preview? Ask for another adjustment before exporting. 预览不满意，可以继续说“再调整一下”；原始场景不覆盖，最终文件写入配置的输出目录。

What You Can Do

• Prepare a product shot: import a model or open a scene, configure selected materials, camera and environment, save a copy and render in one KeyShot process.
• Review before final output: return a PNG to the Agent for composition, material and lighting feedback. Design decisions stay with the user.
• Continue from a save: detect saved .bip changes, copy the scene and preview it without reading the active GUI session.
• Render multiple views: discover all saved cameras, select particular cameras, or queue different scenes for sequential rendering.

Quick Start

Requirements: Node.js 20+, an MCP-compatible client, and a locally installed, licensed KeyShot edition with headless scripting. Windows 11 + KeyShot Studio 2025 / KeyShot 14.1 is tested. Other systems and KeyShot versions are not verified. KeyShot software, licenses and library assets are not included.

Version 1.0.0. This release preserves 19 tools and adds corrected product framing and dependency patches. Client and independent-user acceptance are deferred, not passed. See the release validation record and 1.0 checklist. See Changelog and upgrade notes.

Ask Your Agent to Install

Send this to an Agent that can edit your client's MCP configuration:

Install KeyShot MCP 1.0.0 in my MCP client using npx -y [email protected].Find the full path of my local keyshot_headless.exe and set KEYSHOT_HEADLESS_EXE.Keep the default Documents/KeyShot MCP Outputs folder and external outputs disabled.Use my client's configuration format, restart or reload it, and run keyshot_status.Explain failed checks in plain language. Do not request or upload license keys.Do not upload or publish my scenes or retained render files.Before showing confidential scene metadata or previews to a model service, ask me first.

Configure It Yourself

This is a generic mcpServers JSON example. Use your client's configuration format and replace the executable path with the actual path on your computer.

{  "mcpServers": {    "keyshot": {      "command": "npx",      "args": ["-y", "[email protected]"],      "env": {        "KEYSHOT_HEADLESS_EXE": "C:/Program Files/KeyShot Studio/bin/keyshot_headless.exe"      }    }  }}

Restart the client, run keyshot_status, and check for ready: true. It verifies the executable, output access, bridge, presets and a minimal KeyShot startup.

Workflows

Preview Before Rendering

Inspect C:\projects\speaker.bip and show a preview. Describe framing or materialproblems, but wait for approval before editing or producing a final render.

Recommended sequence: check status → inspect → preview → discuss → approve → render. keyshot_preview_render embeds a PNG and deletes its temporary file after reading. Provide outputPath only when a saved image is needed.

Make a Product Render

Import C:\models\speaker.obj, center it and place it on the ground. Use Isometric,save a scene copy and show a preview first. If the framing clips the model, proposea camera adjustment before rendering the approved scene at standard quality.

keyshot_product_render accepts one model or one saved scene. New models use import composition options by default; existing scenes keep their setup unless changes are requested. In 1.0.0, standard-view cameras for new models without a base scene fit the world-space scene bounds to the render aspect ratio, with 10% edge padding. Explicit distance, absolute camera coordinates and base scenes keep their framing. This includes all scene geometry, not just the main product; review a preview before final rendering.

Compare Materials on One Object

Inspect the saved scene and list material presets. Identify the metal object,change only that object to Brushed Steel in a scene copy, keep the glass unchanged,and show a preview before final rendering.

Use the returned objectPath when names repeat. Material names depend on the local KeyShot library; do not invent them. See material rules.

Continue After Saving in KeyShot

I saved my scene in C:\projects\speaker. Sync the newest .bip in that folder,show me a preview and do not overwrite the original.

keyshot_sync_saved_scene accepts a file or one project folder. Reuse the previous fingerprint on later calls; unchanged saves return changed: false without another copy or render. It is explicit sync, not automatic background monitoring.

Render All Cameras

Render every saved camera in C:\scenes\speaker.bip at preview quality. Continueif one camera fails, and do not overwrite existing images.

For selected cameras use keyshot_batch_render; for different scenes use keyshot_render_queue.

Prepare a Model Without Rendering

Import C:\models\speaker.obj, center it, place it on the ground and adjust thecamera target and environment. Save a scene copy; do not render an image yet.

Use keyshot_import_model when only a prepared .bip is needed.

Adjust the Lens and Environment

Set the Product Hero camera to a 55 mm focal length, rotate the currentenvironment to 45 degrees, save a scene copy and show a preview.

Use keyshot_set_camera and keyshot_set_environment for focused changes.

Render Quality

Explicit dimensions and samples override presets. maxTimeSeconds switches to time-based rendering and cannot be combined with explicit samples. fieldOfView and focalLength are mutually exclusive; camera position and lookAt must be supplied together. A quality preset does not guarantee the final look. Lower-level rendering tools keep their existing defaults when qualityPreset is omitted.

Tool Reference

Start with review and product rendering. The other tools provide focused control; full parameters come from the generated catalog.

The server also provides a product-render MCP Prompt and a workflow MCP Resource. The bundled Agent Skill covers setup, diagnosis and safe tool selection. These are separate interfaces, not extra render tools.

Camera and Material Presets

The bundled camera presets are Front, Back, Left, Right, Top, Bottom and Isometric. Custom camera JSON supports a standardView or absolute position, lookAt and optional up. Both object and array formats are supported; see the preset files.

Material presets reference a local KeyShot library name or material file, not bundled proprietary materials. The server only reads preset JSON; it does not edit it. Use KEYSHOT_CAMERA_PRESETS and KEYSHOT_MATERIAL_PRESETS for custom files. See material assignment and error guidance.

Configuration and Safety

Inputs can come from any trusted local path. Output traversal and symlink/junction escapes are rejected by default. Automatically named product outputs use -2, -3, etc. on collision; explicit paths are not silently renamed. Writing tools reject existing files by default. Set overwrite: true only to replace a distinct output intentionally; it never permits replacing this request's input scene, model, material or environment, including linked aliases. Preview and saved-scene sync never overwrite. Keep scene and image destinations separate. Prefer scene copies. KeyShot headless tasks run sequentially within each server instance to reduce license and file conflicts; this does not coordinate separate MCP server processes.

Processing is local. When an Agent in your MCP client uses these tools, the client may send tool results, scene metadata and preview images to its selected model provider, depending on the client's implementation and settings. KeyShot MCP itself does not upload these results. Review privacy settings before confidential work. No license bypass or arbitrary Python execution is provided. See Security.

Questions and Support

Can it edit the open KeyShot window? No. Save the scene, then sync a copy. The experimental bridge kept Script Runner active and blocked interaction; the stable product does not ship it. Technical explanation.

Does newer MCP support mean ChatGPT Events or GUI support? No. The stable stdio server supports 2026-07-28 and legacy 2025-11-25 clients. Authenticated remote Events delivery is separate and not released. See upgrade notes.

What if setup, materials or rendering fail? Run keyshot_status, read its failed checks and suggestions, verify local material names and try a small preview. Do not treat a tool error as a completed change.

Read Support before sharing logs. Never post private scenes, customer models, credentials, license information or confidential renders publicly.

Development and Roadmap

See Contributing for setup and checks. CI covers Windows/Ubuntu and Node.js 20/24; Linux CI does not establish KeyShot-on-Linux support. The generated cube remains an automated smoke-test fixture. Run npm run smoke:keyshot only with a supported, licensed local KeyShot installation.

Next priorities: real validation on more KeyShot releases and macOS, and further lens controls when stable headless APIs are available. GUI control requires a supported non-blocking integration, not a persistent blocking script.

中文

核心特点

• 把需求变成出图流程： 一个工具串联导入或打开场景、指定对象材质、相机、环境、保存副本和渲染。
• 先看预览再决定： PNG 直接返回给 Agent，用于讨论构图、材质与光线，不替代设计判断。
• 接着已保存的文件工作： 检测 .bip 保存变化，同步副本，不读取 GUI 中未保存的编辑。
• 一次输出多个视角： 自动读取全部相机，也能选择部分相机或顺序处理多个场景。

快速开始

需要 Node.js 20+、支持 MCP 的客户端，以及本机已安装并合法授权、支持 headless 脚本的 KeyShot。已实测 Windows 11 + KeyShot Studio 2025 / KeyShot 14.1；其他系统和 KeyShot 版本尚未实机验证。项目不包含 KeyShot、许可证或官方材质库。

版本 1.0.0： 保留 19 个工具，包含取景修复 及依赖安全修补。客户端与独立用户验收均后置，不代表已通过。 验证记录与正式版准备见验收清单， 版本变更见更新记录和升级说明。

把安装交给 Agent

将下面这段话发给能够修改客户端 MCP 配置的 Agent：

请用 npx -y [email protected] 将 KeyShot MCP 安装到我的 MCP 客户端。找到本机 keyshot_headless.exe 的完整路径，设置 KEYSHOT_HEADLESS_EXE。保留默认“文档/KeyShot MCP Outputs”输出目录，关闭外部输出。按这个客户端实际支持的格式配置，重启或重新加载后运行 keyshot_status。用普通设计师能理解的语言解释失败检查，不索取或上传许可证密钥。不要上传或发布我的场景或保留的渲染文件。如果要把保密场景的元数据或预览发送给模型服务，请先取得我的确认。

手动配置

下面是通用 mcpServers JSON 示例，不代表所有客户端都原样使用此格式。 可执行文件路径需要换成本机实际路径。

{  "mcpServers": {    "keyshot": {      "command": "npx",      "args": ["-y", "[email protected]"],      "env": {        "KEYSHOT_HEADLESS_EXE": "C:/Program Files/KeyShot Studio/bin/keyshot_headless.exe"      }    }  }}

重启客户端，运行 keyshot_status，确认 ready: true。它检查可执行文件、输出目录 权限、bridge、预设以及最小 KeyShot 启动过程。

git clone https://github.com/truman-t3/keyshot-mcp.gitcd keyshot-mcppnpm install --frozen-lockfilepnpm run build

常用工作流

先预览，再正式出图

检查 C:\projects\speaker.bip，给我看预览，说明构图或材质问题。先不要修改，也不要直接输出最终渲染，等我确认。

推荐顺序：状态检查 → 场景检查 → 预览 → 讨论 → 确认 → 正式渲染。 keyshot_preview_render 返回 PNG 后清理临时文件；需要保留图片时才填写 outputPath。

一句话准备产品出图

导入 C:\models\speaker.obj，居中贴地，用 Isometric 视角，保存副本，先给我看预览。如果画面裁切了模型，先提出相机调整建议；确认后再按标准质量渲染。

keyshot_product_render 接受一个模型或一个已保存场景。新模型默认开启导入构图选项； 已有场景没有明确要求时保留原有设置。1.0.0 中，不使用基础场景的新模型在 标准视角下会按世界坐标包围盒和输出宽高比调整取景，四边预留 10% 空间；显式距离、 绝对相机坐标和基础场景保留原有构图。包围盒包含场景全部几何体，不只主产品，正式出图 前仍需检查预览。

只改一个对象的材质

检查场景并列出材质预设，找出金属对象，只把这个对象改为 Brushed Steel。保持玻璃不变，保存副本，先展示预览，不要直接输出最终图。

同名对象应使用检查结果中的 objectPath。材质名称以本机材质库为准，不凭空填写。 具体规则见材质应用说明。

从 KeyShot 最近一次保存继续

我已把场景保存在 C:\projects\speaker。同步这个文件夹里最新的 .bip，给我看预览，不要覆盖原场景。

keyshot_sync_saved_scene 接受文件或一个项目文件夹。再次调用时复用上次内容指纹； 没有新保存时返回 changed: false，不重复复制或渲染。它是显式同步，不是自动后台监控。

渲染全部相机

用预览质量渲染 C:\scenes\speaker.bip 中全部已保存相机。某个相机失败时继续，不要覆盖已有图片。

指定相机用 keyshot_batch_render；不同场景用 keyshot_render_queue。

只整理模型，不渲染

导入 C:\models\speaker.obj，居中贴地，调整相机观察点和环境。保存场景副本，暂时不要渲染图片。

只需要整理好的 .bip 时使用 keyshot_import_model。

调整镜头与环境

把 Product Hero 相机设为 55 mm 焦距，将当前环境旋转到 45 度，保存场景副本并给我看预览。

使用 keyshot_set_camera 和 keyshot_set_environment 分别调整相机与环境。

渲染质量

显式宽高和采样会覆盖预设值。maxTimeSeconds 改用限时渲染，不能与显式 samples 同时使用。fieldOfView 与 focalLength 互斥；position 与 lookAt 必须成对提供。 效果仍需检查，不能把质量预设理解为“保证最终效果”。 底层渲染工具未填写 qualityPreset 时，保留各自原有的默认行为。

工具参考

19 个工具按任务分组列在上方工具表，完整参数由代码自动生成在 工具目录。常用入口是 keyshot_status、keyshot_inspect_scene、 keyshot_preview_render、keyshot_sync_saved_scene 和 keyshot_product_render。

另有产品渲染 Prompt、工作流 Resource 和 Agent Skill。 它们用于指导流程，不是额外的渲染工具。无需记住全部名称，可直接描述设计需求。

相机与材质预设

内置七个相机视角：Front、Back、Left、Right、Top、Bottom 和 Isometric。 自定义相机 JSON 可填写 standardView，或绝对坐标 position、lookAt 与可选 up； 支持对象和数组格式，参见预设文件。

材质预设引用本机 KeyShot 材质库名称或材质文件，不附带专有材质资源。 服务只读取预设 JSON，不自动修改。自定义文件分别通过 KEYSHOT_CAMERA_PRESETS 和 KEYSHOT_MATERIAL_PRESETS 配置，材质规则及错误处理见材质应用说明。

配置与安全

输入可以来自任意可信本地路径。默认拒绝越界路径及软链接/目录联接逃逸。 产品工具自动命名的输出重名时使用 -2、-3 等编号，显式路径不被静默改名。 写入工具默认拒绝覆盖已有文件。只有确实要替换另一个输出文件时才设置 overwrite: true；即使开启，也不能覆盖本次调用的输入场景、模型、材质或环境文件， 包括指向它们的链接。预览与保存同步始终不覆盖。场景和图片必须使用不同路径，平时使用场景副本。 同一个服务实例内的 KeyShot 后台任务按顺序执行，以减少许可证和文件冲突； 多个独立 MCP 服务进程之间不共享这一排队机制。

处理在本机完成。MCP 客户端中的 Agent 使用工具时，返回的工具结果、场景元数据和 预览图可能根据客户端的实现与配置发送给所选模型服务。 KeyShot MCP 本身不主动上传 这些内容。保密项目请先核对隐私设置。项目不提供许可证绕过或任意 Python 执行。 更多说明见 SECURITY.md。

常见问题与支持

能控制正在打开的 KeyShot 窗口吗？ 不能。先保存，再同步副本。实验 Bridge 会持续占用 Script Runner，阻挡正常操作，因此没有作为稳定功能发布。 完整原因见 GUI 能力边界。

支持新 MCP 协议，就能用 ChatGPT Events 或实时控制吗？ 不能这样推断。 稳定 stdio 服务支持 2026-07-28 和旧 2025-11-25 客户端；远程鉴权与事件投递属于 尚未发布的独立集成，详见升级说明。

安装、材质或渲染失败怎么办？ 先运行 keyshot_status，查看失败检查和建议， 核对本机材质名称，再尝试小尺寸预览。不要把报错当成已经完成修改。

开发与路线图

环境准备与完整测试命令见贡献指南。CI 覆盖 Windows/Ubuntu 和 Node.js 20/24；Linux CI 不代表 KeyShot 已在 Linux 上实机可用。原有立方体保留为 自动 smoke test 夹具，npm run smoke:keyshot 只在已安装并合法授权 KeyShot 的机器运行。

后续重点：更多 KeyShot 版本和 macOS 实机验证，以及稳定 headless API 可用时的镜头 控制。实时 GUI 需要受支持的非阻塞接入方式，不采用长期阻挡窗口的脚本。
