Prerequisites

Before starting, you'll need to have setup your Developer account on the Runway API, setup Billing, and also created an API Key.

You'll also need Node.js setup.

Setup

1. Clone this repository and save it to a folder on your computer. Remember where you saved this folder because you'll need it in a later step.

2. Run npm install in the folder, then npm run build. You should now see a new folder called build with a index.js file inside.

Windows

notepad %APPDATA%\Claude\claude_desktop_config.json

4. Add the runway-api-mcp-server to the config, make sure to replace the file path and Runway API key.
