secondbrain-connect

Give Claude, ChatGPT, Cursor, and any MCP-capable assistant a shared, persistent memory backed by your SecondBrain notes. Save a fact in one assistant, recall it in another. Stop starting from zero every session.

Quick start

npx secondbrain-connect

One Apple or Google sign-in (no password, no token to copy). It mints a revocable access token, auto-configures every MCP client it can find (Claude Code, Claude Desktop, Cursor), and installs the memory skill. Restart your assistant and you are done.

Requires the SecondBrain app and a Pro subscription (upgrade in the app).

What your assistant can do

• Recall what you told it in past sessions, across every assistant you connect.
• Remember durable facts, decisions, and fixes into your own SecondBrain folders.
• Connect related notes, and set calendar events or reminders.

Everything runs server-side in your own SecondBrain. Memories are ordinary notes in your folder tree, visible and editable in the app.

Commands

npx secondbrain-connect            sign in and configure everything
  --apple | --google                pick provider (default: Google)
  --project                         write ./.mcp.json instead of user config
  --agent <name>                    folder for this assistant's notes (default: claude)
  --label <text>                    label for the token
  --port <n>                        loopback port (default: 8788)

npx secondbrain-connect revoke <id|--all>
npx secondbrain-connect logout

Privacy

The CLI only performs the sign-in and writes local MCP config. The access token is opaque, scoped to MCP only, and revocable at any time with revoke. The server re-checks your Pro status on every call. Learn more at secondbrain.icu.
