Overview

Description from the maker (original English)

Build editable 3D scenes, direct characters and cameras, and export AI video references with MCP.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Design, images & audio

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save
  4. If it asks you to sign in, sign in with the maker

Common questions

Is Reelpen safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 40 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

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.

[Open Reelpen](https://beta.reelpen.ai/) · [Connect your AI](https://beta.reelpen.ai/guides/connect-your-ai) · [Watch the demo](https://www.youtube.com/watch?v=MnRJVpZwn2A)

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

SettingValue
Server nameReelpen
Remote URLhttps://beta.reelpen.ai/mcp
TransportStreamable HTTP
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.
