I built an MCP server that lets Claude watermark images - here's how

I built an MCP server that lets Claude watermark images I'm a solo dev and I built Markly , an image watermarking service. It started as a web tool, then I added a REST API, and recently I built an MCP server so that Claude can watermark images directly. This post covers what MCP is, why I built the server, and how you can use it. What is MCP? MCP (Model Context Protocol) is an open standard by Anthropic that lets AI assistants connect to external tools. When you add an MCP server to your Claude configuration, Claude gains new capabilities - it can call your tools, pass parameters, and handle the results. Think of it as giving Claude hands. Instead of just talking about watermarks, Claude can actually apply them. The problem I was solving My workflow used to be: Open photo in editor Add text layer Adjust opacity, position, font Export Repeat 50 times The API automated steps 1-4. But I still had to write the API call, manage parameters, handle the response. MCP eliminated that too. Setu
