概览

AI 生成的概览

让助手查看并编辑 Reelpen 的实时 3D 场景、摆放角色与摄像机，并导出参考视频或 PNG 帧。

功能: Reelpen 是一个面向 AI 视频预演的远程 MCP 服务器，对应浏览器中的 3D 场景搭建工具。助手可通过它读取已授权实时场景的当前能力，然后布置角色、道具与环境，规划行走或奔跑路线、停顿及受支持的动作序列，并摆放摄像机、设置注视目标与预览镜头运动。它还能以浏览器支持的格式导出参考视频和 PNG 帧，并在单独授予的账户权限下处理已保存的项目和分镜板。
适用场景: 当你希望助手协助搭建 3D 场景、规划跟拍镜头或镜头运动、比较分镜角度，或为后续 AI 视频流程生成参考视频与关键帧时适用。它用于预演，不生成最终视频。
运行要求: 需要远程 MCP 端点 Streamable HTTP，且 AI 客户端需支持远程 MCP 以及 Reelpen 的 OAuth 发现与注册流程。登录使用 Google OAuth，并需在 Reelpen 编辑器标签页中打开目标项目并允许该标签页实时访问。未声明任何软件包、环境变量或请求头。

安装前请注意

连接账户与允许实时编辑标签页是两项独立授权；Stop 只关闭实时访问，不会撤销另行授予的已保存项目或分镜板权限，需在 Connected apps 中移除连接才能撤销。助手可以修改已授权的场景，因此改动前应先确认其报告的项目与对象与打开的编辑器一致，并注意场景撤销不覆盖所有已保存的账户操作。Reelpen 为免费测试版且无需银行卡，但你的 AI 助手和外部视频生成服务有各自的访问规则与费用。导出的参考仅为预演用途，最终生成视频由另一项服务完成，还原度无法保证。

安装

在 SourceWeft 中

打开控制台中的 Reelpen，将其添加到工作区。
为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。远程服务在工作区中配置后即可从网页运行时运行。

其他 MCP 客户端

把它添加到你客户端的 mcpServers 配置中。

README

Reelpen — 3D scene building for AI video, with MCP

Build an editable 3D scene, direct character and camera movement, then export references for your AI video workflow. Reelpen runs in a desktop browser and offers an authenticated remote MCP connection for compatible AI assistants.

What Reelpen does

Arrange characters, props and environments in an editable 3D scene.
Plan walking/running routes, pauses and supported character action sequences.
Position cameras, choose look targets and preview camera movement.
Export reference video and PNG frames using supported browser formats.
Connect a compatible AI assistant to inspect and edit an allowed live scene.
Work with saved projects and film boards through separately granted account permissions.

Reelpen is in free beta; no payment card is required. Your AI assistant and external video-generation services have their own access rules and charges. Check current access information for changes.

Connect through MCP

Setting	Value
Server name	Reelpen
Remote URL	`https://beta.reelpen.ai/mcp`
Transport	Streamable HTTP
Authentication	OAuth; sign in to Reelpen with Google
Live editing	Open the desired project and choose AI: allow in this tab

Use an AI client that supports remote MCP and Reelpen's OAuth discovery and registration flow. Add the remote URL in the client's MCP/connector settings, complete sign-in and review the requested permissions. Then open the desired project in Reelpen using the same account and allow that editor tab.

Start with a read-only check:

Use Reelpen to read my allowed scene. Tell me the project name, the objects and cameras you can see, and whether the scene is live. Do not change anything.

Confirm that the reported project and objects match the open editor before making changes.

Try a small edit:

In my allowed Reelpen scene, keep existing objects. Add one Dolly character with a short walking route and a camera that follows it. Read the current capabilities first, make the change as one batch, then show me a camera preview.

Watch the result and play the entire shot. Wait for Saved before leaving.

Task	Guide

Plan sit, wait, stand and other supported actions	Character motion reference
Choose moving versus still references	Reference video and keyframes

Permissions and limits

Connecting an account and allowing a live editor are separate steps. Stop closes live access; it does not revoke separately granted saved-project or film-board access. Remove the connection in Connected apps to revoke it. Scene Undo covers editor history, not every saved account operation.

AI assistants should read the current capabilities before editing. Builder coverage is evolving; not every Builder control is promised through MCP. Motions are for previsualization. Inspect seat contact, turns, framing and the whole timeline before exporting.

Reelpen prepares references. Final generative video is produced by a separate service, and reference fidelity depends on that service. This repository does not claim that a video model will reproduce a shot exactly.

A local DWG experiment is not a released DWG importer, BIM system or construction-documentation feature.
