The Scenario.com MCP Server is designed to work with the Scenario.com API, enabling image generation and background removal. It provides tools and methods to interface with the API, offering examples and scripts for ease of use.

Scenario.com MCP Server

This project provides a Model Context Protocol (MCP) server for the Scenario.com API. The server allows you to generate images from text prompts and remove backgrounds from images using the Scenario.com platform (https://app.scenario.com/).

    • Erase background from image.py: Example of background removal
    • Get job data by job ID.py: Example of checking job status
    • download_image.py: Example of downloading generated images

  • scripts/: Utility scripts for running the server and examples

    • start_server.bat/start_server.sh: Scripts to start the MCP server using the mcp dev command

  • assets/: Sample images and resources

    • warrior_no_background.png: Sample image with background removed
    • warrior_with_background.jpg: Sample original image

  • docs/: Documentation

    • README.md: Project documentation
    • DESIGN_PLAN.md: Design documentation

  • scenario-ai/: Virtual environment for the project

Setup

  1. Clone this repository

  2. (Recommended) Set up a virtual environment:

    # Using venv
python -m venv scenario-ai
.\scenario-ai\Scripts\activate  # Windows
source scenario-ai/bin/activate  # Linux/macOS

# Or using conda
conda create -n scenario-ai python=3.8
conda activate scenario-ai

  3. Install the required dependencies (either method works):

    # Method 1: Using requirements.txt
pip install -r src/requirements.txt

# Method 2: Using setup.py (installs as package)
pip install -e .

  4. Create a .env file in the root directory with your Scenario.com API credentials:

    SCENARIO_API_KEY=your_api_key
SCENARIO_API_SECRET=your_api_secret
SCENARIO_MODEL_ID=model_KMeeJU9mpcfHKB7a1hv9vyW9  # Change to preferred model

    Important: The server loads environment variables directly from this .env file, so make sure it's properly configured.

  5. Install the MCP SDK and python-dotenv:

    pip install mcp

  6. Add this MCP server configuration to your Cline/Roo-Cline/Cursor/VS Code settings:

    "scenario-ai": {
  "command": "python",
  "args": [
    "path/to/your/local/scenario.com-mcp-server/src/server.py"
  ],
  "disabled": false,
  "autoApprove": [],
  "alwaysAllow": []
}

    Note: Environment variables are loaded from the .env file, so they don't need to be specified in the MCP server configuration.

Running the Server

To run the server:

# Standard method
python src/server.py

# Recommended: Using MCP dev mode (starts inspector)
mcp dev src/server.py

# Or use the provided scripts:
# Windows
scripts/start_server.bat

# Linux/macOS
./scripts/start_server.sh

When running with mcp dev, you'll see output like:

Starting MCP inspector...
āš™ļø Proxy server listening on port 6277
šŸ” MCP Inspector is up and running at http://127.0.0.1:6274 šŸš€
New SSE connection

Available MCP Tools

The Scenario.com MCP Server provides the following tools that can be used with the Roo-Cline interface:

Tools

  1. generate_image: Generate an image from a text prompt

    • Parameters:
      • prompt (required): The text prompt describing the image to generate
      • model_id (optional): The model ID to use (defaults to environment variable)
      • negative_prompt (optional): Text describing what to avoid in the image
      • num_samples (optional): Number of images to generate

  2. remove_background: Remove the background from an image

    • Parameters:
      • asset_id (required): The asset ID of the image to process

Resources

  1. status://info: Get information about the server status
  2. job://{job_id}: Get information about a job
  3. asset://{asset_id}: Get information about an asset

Using the Examples

See the examples/client_example.py file for an example of how to use the server.

To run the example client:

# Windows
scripts/run_client_example.bat

# Linux/macOS
./scripts/run_client_example.sh

Scripts

The scripts/ directory contains utility scripts to help you run the server, examples, and tests:

Server Scripts

  • start_server.bat (Windows) / start_server.sh (Linux/macOS): These scripts start the MCP server using the mcp dev command, which runs the server in development mode.

    Usage:

    # Windows
scripts/start_server.bat

# Linux/macOS
./scripts/start_server.sh

Example Scripts

  • run_client_example.bat (Windows) / run_client_example.sh (Linux/macOS): These scripts run the example client that demonstrates how to use the MCP server.

    Usage:

    # Windows
scripts/run_client_example.bat

# Linux/macOS
./scripts/run_client_example.sh

Test Scripts

  • run_tests.bat (Windows) / run_tests.sh (Linux/macOS): These scripts run the test suite that verifies the MCP server functionality.

    Usage:

    # Windows
scripts/run_tests.bat

# Linux/macOS
./scripts/run_tests.sh

Running Tests and Viewing Documentation

To run the tests and view the documentation:

# Windows
scripts/run_tests.bat

# Linux/macOS
./scripts/run_tests.sh

The test_server.py file provides comprehensive documentation on how to use the Scenario.com MCP Server, including:

  • Server setup instructions
  • Available tools and their parameters
  • Available resources
  • Example usage with the Roo-Cline interface
  • A complete workflow for generating images and removing backgrounds

Running the tests will display this documentation, which serves as a guide for using the MCP server.

Troubleshooting

Server Won't Start

If you encounter issues starting the server, check the following:

  1. Make sure the MCP SDK and python-dotenv are installed:

    pip install mcp python-dotenv

  2. Check that your Python environment has all the required dependencies:

    pip install -r src/requirements.txt

  3. Verify that your .env file in the root directory is properly configured with your Scenario.com API credentials:

    SCENARIO_API_KEY=your_api_key
SCENARIO_API_SECRET=your_api_secret
SCENARIO_MODEL_ID=your_model_id

  4. If you're using a virtual environment, make sure it's activated before running the server.

API Errors

If you encounter errors when using the API:

  1. Check that your API credentials are correct.
  2. Verify that the model ID you're using is valid.
  3. Check the Scenario.com API documentation for any service disruptions or changes.
