Mochify MCP server

mochify-cli

A command-line tool and MCP server for mochify.app — a fast, privacy-first image compression and conversion API powered by a native C++ engine.

Compress and convert images to modern formats (AVIF, JXL, WebP, Jpegli) from your terminal, work on PDFs, or give AI assistants like Claude direct access to the same engine over the Model Context Protocol — either as a local stdio server (mochify serve) or the hosted one at mcp.mochify.app, which needs no install at all.

Authentication

Sign in with your mochify.app account to unlock your full quota:

mochify auth login

This opens your browser, where you sign in and authorize the CLI. Credentials are saved automatically to ~/.config/mochify/credentials.toml — no environment variables or manual key copying required. Both the CLI and MCP server pick them up automatically.

mochify auth status   # check whether you're signed in
mochify auth logout   # remove saved credentials

Without an account you get 3 images per batch (IP-based). With a free account: 25 images/month. Sign up at mochify.app.
