Description

Creating device-framed screenshots and screen recordings for my iOS, macOS, and tvOS apps is a pain so I looked for a tool, preferably with an MCP server that could do it for me. I couldn't find anything that did everything I wanted (images and videos, scaling, transparent backgrounds for both, etc) so I made one: Bezelbub.I started with a macOS app. Handy when putting together App Store listings, which was my first use case. Then I added support for video in/out. But I realized I wanted framed screenshots in more places than that (like social posts) so I made an iOS app that would allow me to just snap a screenshot on-device, share it to Bezelbub, choose my options, and share it directly from there. Neat.But I still found myself doing a lot of the work, which in the age of Claude Code is goofy. So I created a command-line version and a Homebrew tap. Works a treat. I intentionally made it agent-first (no interactivity, complete docs in --help, JSON output, meaningful error codes, suggestions, etc).Along the way I added support for videos with transparent backgrounds, which is more of a pain than you might think. (It exports HEVC mov files and needs to convert that to WebM, but older ffmpeg builds don't handle transprencyin that conversion correctly, so it uses ProRes 4444 as a master.)The final step was to create an MCP wrapper so LLMs don't have to re-learn how to use the thing every time.It's all freely available with no ads, all local processing so nothing leaves your device, etc. Just a labor of love that I think other people might find useful.The CLI and MCP server are macOS-only.Bezelbub product page: https://dgrlabs.co/bezelbubMCP server: https://github.com/cwooddgr/bezelbub/tree/main/bezelbub-mcp
