Dejo MCP server

Dejo

A browser your AI agent remembers. It learns a website once. Every run after that is one tool call, with zero model calls.

Your AI can use websites. But it forgets how, every single time. Dejo makes it remember.

Dejo gives Claude Code, Codex, Cursor or any MCP client a browser with a memory. Your agent walks a website once: signing in, clicking, reading. Dejo writes down the route. Every run after that follows the route instead: one tool call, no page reading, zero model calls. When the site changes, Dejo repairs the one step that moved and keeps the rest.

Install

Python 3.11 or newer.

pip install dejo-mcp
playwright install chromium      # the browser, a separate download of about 150 MB

Then connect it to your agent:

Dejo is one stdio server with no arguments, so any agent that can run an MCP server can use it.

No API key, no account. Dejo never calls a model. Your agent does the thinking, and the memory is a local file on your machine.

Check the install at any time. It names anything missing and the command that fixes it:

dejo doctor

Quick start

Ask your agent for something on a website, in your own words:

Go to github.com/microsoft/playwright and tell me how many open issues it has.

The first time, your agent learns it: Dejo opens the page and shows it, one line per control, and your agent sends the steps back in one call (click link "Issues", then read ... as open issues). The read is what Dejo saves. Ask again tomorrow, in a brand-new chat, and it is one call:

done: "count open issues" on github.com (profile default), 2 steps replayed in 1391 ms, no page reading.
open issues = 117
next: report the answer exactly as read and stop. Every step was checked as it ran.

Prefer a terminal? Everything works without an MCP client:

dejo sites                                            # what it remembers
dejo run "count open issues" --site github.com        # replay, no model involved
dejo run "count open issues" --site github.com --json # one JSON line, for cron and scripts
dejo show github.com                                  # the route, step by step
dejo forget --site github.com                         # make it forget
