From the repository
Add the MCP server to your client config (Claude Desktop, Cursor, ElizaOS, etc.) with the URL https://image-resize.api.klymax402.com/mcp. For HTTP, send a POST request to /api/resize; any x402-aware client (e.g., @x402/fetch) handles the 402 → sign → retry cycle automatically. The tool is media_resize_image.
Claude Desktop / Cursor
Paste into your MCP client config file to install this server.
