Manim MCP

A Docker-based environment for creating mathematical animations with Manim, featuring both a CLI interface and a web API with Model Context Protocol (MCP) support for AI assistants.

📑 Overview

This project provides:

1. Containerized Manim Environment: Run Manim in an isolated, reproducible Docker environment
2. Web API: Create and manage Manim animations via HTTP requests
3. MCP Integration: Direct interaction with AI assistants like Claude
4. File Management: Upload scripts and download generated animations

🚀 Quick Start

Prerequisites

• Docker and Docker Compose installed on your system

Installation

Option 1: Use the Prebuilt Image (Recommended)

Simply pull the prebuilt image from Docker Hub:

docker pull wstcpyt/manim-docker-mcp:latest

Then run it with docker-compose:

docker compose up -d

Option 2: Build Locally

1. Clone the repository:

   git clone https://github.com/YOUR_USERNAME/manim-docker-mcp.git
   cd manim-docker-mcp
   

   Copy

2. Build the Docker images:

   docker compose build
   

   Copy

Usage

CLI Mode

Create a Python file in the animations directory (see example below), then run:

docker compose run manim -pql animations/example.py ExampleScene

API Mode

Start the API server:

docker compose up -d manim-api

Access the API documentation at http://localhost:8000/docs

🎬 Creating Animations

Basic Example

Create a file animations/example.py:

from manim import *

class CircleToSquare(Scene):
    def construct(self):
        circle = Circle()
        circle.set_fill(BLUE, opacity=0.5)

        square = Square()
        square.set_fill(RED, opacity=0.5)

        self.play(Create(circle))
        self.wait()
        self.play(Transform(circle, square))
        self.wait()

Running the Animation

# CLI mode with preview (-p), low quality (-ql)
docker compose run manim -pql animations/example.py CircleToSquare

# API mode
curl -X POST "http://localhost:8000/run-manim?filepath=/manim/temp/circle_example.py&scene_name=CircleToSquare&quality=low_quality"

🤖 AI Assistant Integration (MCP)

This project supports the Model Context Protocol (MCP), enabling AI assistants to:

1. Create Manim scripts based on natural language descriptions
2. Run animations and provide download links
3. Browse and manage generated media files

Example MCP session:

User: Create an animation showing a circle morphing into a square
AI: I'll create that for you...

🔍 Advanced Usage

Custom LaTeX

The container includes a minimal LaTeX installation. Custom LaTeX can be used in animations:

formula = MathTex(r"\int_{a}^{b} f(x) \, dx = F(b) - F(a)")
self.play(Write(formula))

Mounting Custom Directories

Modify the docker-compose.yml file to mount additional directories:

volumes:
  - ./my_custom_dir:/manim/custom

🛠️ Troubleshooting

Common Issues

• Docker not running: Make sure Docker daemon is running
• Permission errors: The container needs write access to mounted volumes
• Missing media: Check the correct output directory (media/ for CLI, output/ for API)
