Tools

This server runs on your machine, so its tool list is not fetched before install — the README below describes what it offers.

README

mantis

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

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.

How it works

Agent sends open/click to Mantis; Mantis reads the page in Chromium, numbers each control and returns only what changed; CAPTCHA, 2FA and payment go to you

What the agent sees

A shop page with a cookie popup becomes 8 numbered lines; after click #3 only the changes come back

Results

30 real-site tasks, Codex gpt-6-luna as the agent, graded by a blind judge (gpt-6.1-sol):
