paraplex-mcp

Connect Claude Code — or any MCP client — to the Paraplex tab you have open. Paraplex is a 3D motion design studio in the browser, with an AI assistant that edits real layers and keyframes. With this server, an agent in your terminal can build and change scenes in your tab with the same tools the assistant uses, look at frames as it goes, and export.

claude mcp add paraplex -- npx -y paraplex-mcp

Then ask Claude Code for a piece — "a 10-second launch video with three glass cards and our logo" — and it will tell you how to connect:

1. Open Paraplex at https://app.paraplex.ai.
2. Menu › Connect an agent, and enter the port and the six-digit code Claude Code gives you.

A banner shows in your tab while an agent is connected; disconnect it there any time.

What it can do

Tool	What it does
connection	Whether a tab is attached; if not, the port and code to give you
scene	The open scene: canvas, duration, time, every layer
list_tools, run_tool	The assistant's verbs (build_scene, add_text, set_keyframes, add_camera_move…) and running one
list_templates, apply_template, new_project	Start from a template or a blank file
set_time, frame, frames, export_png	Look at the piece at any time, as its export draws it
scene_facts	Where every layer lands in the frame, type sizes on the frame, the camera
export	Export to a file on this computer (./paraplex-exports, or PARAPLEX_OUT_DIR) with any of the Export section's options for that export only: image or video, format, scale, frame rate, part of the timeline, no background, one artboard or all, App Store / Keynote / PowerPoint / Google Slides presets. Large files stream in pieces, so there is no size ceiling
render_variants	A render per row of data (rows or CSV), each column filling the layer of its name
export_video	The video at the scene's own settings (kept from 0.2)
import_file	Send a file from this computer into the scene, as a drop takes it: a picture or video, sound, a 3D model, Lottie, Figma frames, an SVG, a font
import_hyperframes	Bring in a HyperFrames project from a folder or .zip on this computer: one code layer, its sound on the timeline
undo, redo	Step back or forward, as ⌘Z does
review_sheet, review_artboards	Frames across the piece as one sheet, with what runs past the frame, small or low-contrast type, and motion hitches; or the piece on 9:16, 4:5, 1:1 and 16:9
list_projects, open_project, save_project	Your projects in this browser and your account; open one, or save the scene as one
list_design_systems, apply_design_system	Paraplex's design systems and yours; apply one in a single undo step
list_skills, load_skill, read_skill_file, write_skill	The assistant's skills: read them, or write one into your library

Every edit lands in your tab as one undo step, so you can step back through anything the agent did.

Privacy and safety

• The server listens on this computer only (port 47821; pass another as npx paraplex-mcp 48000).
• Only a Paraplex page can connect, and only with the one-time code.
• Nothing is sent anywhere else: the scene stays in your tab, exports are written where you ran the server, and a file you send in goes only to your tab. An agent reaches only what you are signed in to in that tab.
• AI used inside Paraplex is metered by your Paraplex plan as usual; the agent's own model is your Claude Code's.

Browsers

Chrome, Edge or Arc (other browsers may not let a website reach your own computer). If your browser asks to let app.paraplex.ai connect to devices on your local network, allow it: that is this server.
