インテグレーション

A TypeScript-based Model Context Protocol (MCP) server enabling integration with PiAPI for media content generation using platforms like Midjourney, Flux, and others through MCP-compatible applications.

GitHubで見る

piapi-mcp-server

A TypeScript implementation of a Model Context Protocol (MCP) server that integrates with PiAPI's API. PiAPI makes user able to generate media content with Midjourney/Flux/Kling/LumaLabs/Udio/Chrip/Trellis directly from Claude or any other MCP-compatible apps.

Features (more coming soon)

Note: Time-consuming tools like video generation may not complete due to Claude's timeout limitations

Working with Claude Desktop Example

Prerequisites

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

Installation

Installing via Smithery

To install PiAPI MCP Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install piapi-mcp-server --client claude

Manual Installation

Clone the repository:

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

Install dependencies:

npm install

Build the project:

npm run build

After building, a dist/index.js file will be generated. You can then configure this file with Claude Desktop and other applications. For detailed configuration instructions, please refer to the Usage section.

(Optional) Test server with MCP Inspector:

First, create a .env file in the project root directory with your API key:

PIAPI_API_KEY=your_api_key_here

Then run the following command to start the MCP Inspector:

npm run inspect

After running the command, MCP Inspector will be available at http://localhost:5173 (default port: 5173). Open this URL in your browser to start testing. The default timeout for inspector operations is 10000ms (10 seconds), which may not be sufficient for image generation tasks. It's recommended to increase the timeout when testing image generation or other time-consuming operations. You can adjust the timeout by adding a timeout parameter to the URL, for example: http://localhost:5173?timeout=60000 (sets timeout to 60 seconds)

The MCP Inspector is a powerful development tool that helps you test and debug your MCP server implementation. Key features include:

Interactive Testing: Test your server's functions directly through a web interface
Real-time Feedback: See immediate results of your function calls and any errors that occur
Request/Response Inspection: View detailed information about requests and responses
Function Documentation: Browse available functions and their parameters
Custom Parameters: Set custom timeout values and other configuration options
History Tracking: Keep track of your previous function calls and their results

For detailed information about using the MCP Inspector and its features, visit the official MCP documentation.

Usage

Connecting to Claude Desktop

Add this to your Claude Desktop configuration file (~/Library/Application Support/Claude/claude_desktop_config.json on macOS or %APPDATA%\Claude\claude_desktop_config.json on Windows):

{
  "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 file, you need to restart Claude for Desktop. Upon restarting, you should see a hammer icon in the bottom right corner of the input box. For more detailed information, visit the official MCP documentation

Connecting to Cursor

Note: Following guide is based on Cursor 0.47.5. Features and behaviors may vary in different versions.

To configure the MCP server:

Navigate to: File > Preferences > Cursor Settings, or use the shortcut key Ctrl+Shift+J
Select "MCP" tab on the left panel
Click "Add new global MCP server" button in the top right
Add your configuration in the opened mcp.json file

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

After configuration, you'll see a "piapi" entry in MCP Servers page
Click the Refresh button on the entry or restart Cursor to connect to the piapi server

To test the piapi image generation:

Open and select "Agent mode" in Cursor Chat, or use the shortcut key Ctrl+I
Enter a test prompt, for example: "generate image of a dog"
The image will be generated based on your prompt using piapi server

To disable the piapi server:

Navigate to the MCP Servers page in Cursor Settings
Find the "piapi" entry in the server list
Click the "Enabled" toggle button to switch it to "Disabled"
