Lets AI agents browse the web as short, numbered text instead of screenshots.

perzian.dev/mantis · by Perzian

Mantis shows the agent what a person would notice on a page, in a few lines, and lets it act by number. It works with Claude Code, Codex, Cursor or your own agent as an MCP server. Install in two commands.
