## What it does

Mochify is a CLI and MCP server for mochify.app, an image compression and conversion service running a native C++ engine. You can hook it up to an assistant in two ways: locally with `mochify serve` over stdio, or through the hosted endpoint at `https://mcp.mochify.app/mcp`, which needs nothing installed.

The toolset covers conversion to `jpg`, `png`, `webp`, `avif` and `jxl`, resizing, cropping by saliency or by a rectangle you specify, rotation, background removal, hiding faces and regions, and PDF work. A `--prompt` mode takes plain-language instructions like “optimise for eBay” and works out the parameters itself. Quality is picked automatically unless you pass `-q`.

Without an account you get 3 images per batch, limited by IP; a free account raises that to 25 images a month. Signing in with `mochify auth login` opens a browser and stores credentials in `~/.config/mochify/credentials.toml`, where both the CLI and the MCP server read them. On a headless machine, such as over SSH, use `mochify auth login --no-browser` and enter the printed code on another device.
