Open-source MCP server dryplate adds 10 local image tools to your AI agent
ServerErr500 · reddit · 2026-11-10
A Redditor released @dryplate/mcp (MIT), a local image-tools MCP server installable via npx -y @dryplate/mcp that gives agents like Claude Desktop and Cursor 10 tools: convert, resize, compress, crop, rotate, blur, watermark, strip metadata, merge, and thumbnails, with iPhone HEIC support via libheif. Everything runs locally with no uploads.
Notable design choices from real agent usage:
- Tools take file paths and write files — no base64, so image bytes never enter the context window
- Outputs land next to inputs (e.g. photo-resized.jpg); existing files are only overwritten with overwrite: true
- Mismatched output extensions are an error, so JPEG bytes never land in a .png
- / paths work; relative paths are refused since most clients start servers in /
One gotcha: attaching an image to Claude Desktop chat sends it to the sandbox — the server never sees it, so type the path instead.
