概覽

AI 產生的概覽

讓助理檢視並編輯 Reelpen 的即時 3D 場景、擺放角色與攝影機，並匯出參考影片或 PNG 影格。

功能
Reelpen 是針對 AI 影片預覽的遠端 MCP 伺服器，對應瀏覽器中的 3D 場景建構工具。助理可透過它讀取已授權即時場景的目前能力，接著安排角色、道具與環境，規劃行走或奔跑路線、停頓及支援的動作序列，並擺設攝影機、設定注視目標與預覽鏡頭運動。它也能以瀏覽器支援的格式匯出參考影片與 PNG 影格，並在另行授予的帳號權限下處理已儲存的專案與分鏡板。
適用情境
當你希望助理協助搭建 3D 場景、規劃跟拍鏡頭或鏡頭運動、比較分鏡角度，或為後續 AI 影片流程產出參考影片與關鍵影格時適用。它用於預覽，不產生最終影片。
執行需求
需要遠端 MCP 端點 Streamable HTTP，且 AI 用戶端需支援遠端 MCP 以及 Reelpen 的 OAuth 探索與註冊流程。登入使用 Google OAuth，並需在 Reelpen 編輯器分頁中開啟目標專案並允許該分頁即時存取。未宣告任何套件、環境變數或標頭。
安裝前請注意
連接帳號與允許即時編輯分頁是兩項獨立授權；Stop 只關閉即時存取，不會撤銷另行授予的已儲存專案或分鏡板權限，需在 Connected apps 中移除連接才能撤銷。助理可以修改已授權的場景，因此變更前應先確認其回報的專案與物件和開啟的編輯器一致，並注意場景復原不涵蓋所有已儲存的帳號操作。Reelpen 為免費測試版且不需信用卡，但你的 AI 助理與外部影片生成服務有各自的存取規則與費用。匯出的參考僅供預覽，最終生成影片由另一項服務完成，還原度無法保證。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Reelpen，將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

其他 MCP 客戶端

把它新增到你客戶端的 mcpServers 設定中。

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.

AuthenticationOAuth; sign in to Reelpen with Google
Live editingOpen 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.

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.
