Step one

Create your Penny account

Keep your memories and notes available across the AI tools you use. Create your account, then connect your assistant using the instructions below.

Step two

Connect your assistant

One connection, in the tool you already talk to. Each of these speaks the Model Context Protocol, so it is the same three steps and the same address every time.

Claude
Web and desktop

Claude

Set it up once and both Claude on the web and the desktop app pick it up.

  1. Open Settings, then Connectors.

  2. Add Penny as a custom connector, using the address below.

  3. Authorize in your browser, then verify the connection.

https://app.mypenny.ai/mcp

  • • Same address for web and desktop
ChatGPT
Web and desktop

ChatGPT

Set it up on the web and the desktop app picks it up.

  1. Enable Developer mode in Settings — custom apps are hidden until you do.

  2. Add Penny as a custom app, using the address below.

  3. Authorize in your browser, then verify the connection.

https://app.mypenny.ai/mcp
  • • Requires a paid plan — Plus, Pro, Business, Enterprise or Edu
  • • Developer mode has to be on before the option appears
Step three

Set up your coding tools

Each of these installs as a plugin, so your memory, projects and skills come with you into the editor. Run the commands as they are written.

Claude Code
Plugin

Claude Code

The plugin brings the Penny skill, the MCP server, hooks and transcript learning in one install. Run both commands inside any Claude Code session.

/plugin marketplace add HelperLabs/mypenny-plugin
/plugin install mypenny-claude@mypenny

On your next session the plugin prints the exact sign-in command for your machine — run the one it gives you.

  • • One marketplace command per machine, then install
  • • Adds the skill, hooks and MCP server together
Codex
Plugin

Codex

The same plugin from the same marketplace, run from the Codex CLI.

codex plugin marketplace add HelperLabs/mypenny-plugin

To move to a later release:

codex plugin marketplace upgrade mypenny
  • • Same marketplace as Claude Code
  • • Upgrade in place when a new version ships
Cursor
Plugin

Cursor

A per-project installer that writes the hooks and the MCP server config, so you get the same behaviour in Cursor's chat and in Composer.

npx @mypenny/cursor install

Then sign in:

npx @mypenny/core auth login
  • • Run it once per project
  • • Works in both chat and Composer
