markly-mcp-server

MCP (Model Context Protocol) server for Markly.cloud - add watermarks to images via AI agents.

Works out of the box without an API key (free tier with branding). Add an API key to remove branding and increase limits.

markly_watermark_logoAdd a logo watermark to an image via URL
markly_batch_watermarkWatermark up to 20 images, get a ZIP

    "markly": {
      "command": "npx",
      "args": ["-y", "markly-mcp-server"]
    }

That's it. Ask your AI agent:

"Add 'Copyright 2026' as a watermark to this image: https://example.com/photo.jpg";

With an API key (optional)

Get an API key at markly.cloud/developers to remove the "markly.cloud" branding and get higher rate limits.
