PiAPI Image Generation MCP server

This MCP server integrates with PiAPI's API to enable media content generation from Claude or other MCP-compatible apps. It provides access to various AI toolkits including Midjourney, Flux, Kling, LumaLabs, and more - all directly usable from Claude through the Model Context Protocol.

Installation

Prerequisites

• Node.js 16.x or higher
• npm or yarn
• A PiAPI API key (get one at piapi.ai)

Setup Instructions

1. Clone the repository:

git clone https://github.com/apinetwork/piapi-mcp-server
cd piapi-mcp-server

2. Install dependencies:

npm install

3. Build the project:

npm run build

4. Create a .env file with your API key (optional for testing):

PIAPI_API_KEY=your_api_key_here

Using with Claude Desktop

Configuration

Add the server to Claude Desktop by editing the configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "piapi": {
      "command": "node",
      "args": ["/absolute/path/to/piapi-mcp-server/dist/index.js"],
      "env": {
        "PIAPI_API_KEY": "your_api_key_here"
      }
    }
  }
}

After updating your configuration, restart Claude Desktop. You should see a hammer icon in the bottom right corner of the input box, indicating that the MCP server is available.

Using with Cursor

Configuration

1. Navigate to: File > Preferences > Cursor Settings (or use Ctrl+Shift+J)
2. Select "MCP" tab on the left panel
3. Click "Add new global MCP server" button
4. Add your configuration:

{
  "mcpServers": {
    "piapi": {
      "command": "node",
      "args": ["/absolute/path/to/piapi-mcp-server/dist/index.js"],
      "env": {
        "PIAPI_API_KEY": "your_api_key_here"
      }
    }
  }
}

5. Click the Refresh button or restart Cursor to connect

Testing in Cursor

1. Open "Agent mode" in Cursor Chat (shortcut: Ctrl+I)
2. Enter a test prompt like "generate image of a dog"
3. The image will be generated using the piapi server

Disabling the Server

1. Go to MCP Servers page in Cursor Settings
2. Find the "piapi" entry
3. Toggle the "Enabled" button to "Disabled"

Testing with MCP Inspector

You can test the server using the MCP Inspector tool:

npm run inspect

The inspector will be available at http://localhost:5173. For time-consuming operations like image generation, increase the timeout by using a URL parameter:

http://localhost:5173?timeout=60000 (sets timeout to 60 seconds)

Available Features

• Base Image toolkit
• Base Video toolkit
• Flux Image generation
• Hunyuan Video generation
• Skyreels Video generation
• Wan Video generation
• MMAudio Music generation
• TTS Zero-Shot voice generation
• Midjourney Image generation (imagine feature)
• Kling Video and Effects generation
• Luma Dream Machine video generation
• Suno Music generation
• Trellis 3D model generation

Note: Time-consuming operations may not complete due to Claude's timeout limitations.

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
