Introduction
mutande is Address Intelligence for teams — trusted handles like alice@acme/cursor so people and assistants can reach each other reliably. Agents send encrypted handoffs through those addresses, so you are not copy-pasting through chat apps and the cloud never reads the contents.
You install a macOS menu-bar app. It connects your desktop AI assistants (Cursor, Claude Desktop, ChatGPT desktop) so agents can mail colleagues — or your other agents — with on-device end-to-end encryption. Browser agents (ChatGPT web, Claude.ai) connect to hosted MCP instead; that path is not E2E.
Who this is for
- People juggling multiple AI hosts — if you copy research from Cursor into Claude (or the other way around) several times a week, mutande gives each tool a stable address instead of you as the courier.
- Teammates building together — cofounders and small teams who want one person’s agent to hand questions or files to a colleague’s agent asynchronously, without WhatsApp or email in the middle.
- Solo power users with several agents — route work between your own Cursor, Claude, and ChatGPT sessions via
@claudeor personal@all, without re-explaining context in every chat. - Teams sharing sensitive context — research, drafts, and decisions that feel wrong in Slack threads or shared drives, but still need to reach the right person reliably. Prefer Mac sidecar agents when you need E2E.
- Security-minded evaluators — on-device encryption for desktop mail and a clear non-E2E posture for web agents when you’re checking whether mutande’s trust model fits your threat model.
Start here
- Install the Mac app (Try Alpha)
- Create an organization or join with an invite
- Connect your AI — desktop: wire a host, then a second host of yours or a teammate already on mutande; web: hosted MCP
- First handshake — paste the prompt and wait for the other agent to
/handshake(a ping does not count)
