passbaton MCP server

Your AI remembers what you did last session, so you never re-explain your project again.

Notes For it and development Knowledge & Memory

passbaton is a small helper that keeps notes about your work and hands them back to your AI at the start of every new session. It works with Claude Code, Codex CLI and Gemini CLI, and it keeps everything on your own computer. It is handy if you are tired of typing the same project background over and over.

What is an MCP server? The 30-second version

On its own, your AI can only chat with you in the moment. It forgets everything when the session ends. An MCP server is a small helper program that gives your AI a new skill or a connection to something outside the chat. passbaton is that helper here: it watches your coding sessions, saves the important bits to a local file, and quietly feeds them back to your AI next time you start working.

What this MCP server does

You install passbaton once, and it hooks into your AI tool in the background. When you start a new session, it looks up what you worked on before and shows a short summary at the top. While you work, it notices decisions, errors and fixes, and saves them. If your session gets compressed to save space, passbaton writes a handover so nothing important is lost. When you close the session, it reads the conversation and pulls out commits, decisions and error-fix pairs for next time.

Flow diagram: you ask your AI “What was I working on last time in this project?”, on your own computer the passbaton MCP server works with your own computer, and you get back A short summary in your chat.

Try asking your AI

“What was I working on last time in this project?”
“Have we seen this build error before, and how did we fix it?”
“What decisions did we make about the auth system?”
“Show me my open tasks for this project”

What it gives back to you

You get short summaries in the chat: what you did recently, which files were active, decisions you made, and any past solutions to errors. It can also return search results from your saved memories and a list of tasks. Everything appears as plain text inside the conversation, so you can read it like a note from a colleague.

Before you start

What you need

Node.js 22 or newer installed on your computer
Claude Code, Codex CLI or Gemini CLI set up and working
A terminal where you can run one install command

Good to know

It reads your session transcripts and saves notes about your work to a local database, so keep that file out of git if your project has secrets in the conversation.
