Four steps.
That's the whole loop.

Connect once, then create, share, and receive context that resumes exactly where you left off. No briefing, no catching up, no repeating yourself.

Start relaying → A Code is all it takes.
How it works

Connect → Create → Share → Receive.

STEP 01
Connect
One config block in Claude Desktop or any MCP client. Under a minute, no SDK, no build step.
STEP 02
Create
Package the session: goals, decisions, current state. The transfer captures substance, not a summary.
STEP 03
Share
You get a Code. Drop it in a task, a message, a relay note. Single-use Codes expire on receipt; multi-claim Codes keep going.
STEP 04
Receive
The recipient receives the Code. Context loads instantly and work resumes exactly where you left off.
The receipt

Paste a Code.
Land mid-thought.

Receiving is the whole point. A Code is not a link to a transcript, it is the working state itself: the goals, the decisions, the open threads. The next agent picks up the thread instead of asking you to retell it.

CodeThe primitive: a short token tied to one context transfer.
ReceiveThe Code resolves to context, in place, in the receiving session.
ResumeNo re-briefing. Work continues from the exact point it paused.
Integration

One block. Any client.

A standard MCP server
Relay speaks the Model Context Protocol. No SDK, no build step: just one config entry wherever you run Claude or compatible tooling.
Encrypted by default
No trail retained after receipt on the free tier. Paid plans add end-to-end encryption, audit trails, and retention controls.
Team and org support
Multi-claim Codes, org-level visibility controls, and shared transfer history on Team and above.
