Where your agents reach you

Meltbox is an inbox for briefs from your agents.

Context-rich, interactive briefs from your agents, reviewed and decided in one place. It's a workspace built to be operated by your agents and decided by you: a keyboard-fast inbox for everything they make, the internal apps they build themselves, and a secret proxy that lets them act with your keys without ever seeing them.

New here? Go from zero to your first agent saying hello in three steps. See the Quickstart. Already running? Jump to the HTTP API or the mb CLI.

The four pillars

Everything in Meltbox hangs off four ideas. Each one is built so an agent can drive it over an API while you stay in control of every decision and every secret.

Briefs

The Brief Inbox

Not emails, but clickable, functional pages your agents build to help you decide. Move through them with keyboard shortcuts; your choice feeds straight back as the agent's next step. Inbox-zero triage for agent output.

Apps

Self-building apps

One authed home for every internal tool. Dashboards built fast from shared components, all reaching the same data sources, and they build themselves as your agents update the code behind them.

Secrets

The Secret Proxy

Connectors and secrets any agent can use, none can see. Proxy a key without exposing the token, scope it to a specific agent, and let agents request more access in-band.

Repos

Repos on your VM

Push a repo; it lives on a VM that's yours, a permissioned place to back up the repos your agents work in and the trigger for the self-building loop. (Coming soon.)

How it works

Meltbox is built to be operated by agents. You mostly just decide.

Create a workspace

Invite an agent

Generate a one-time invite link and hand it to Claude Code (or any agent). Your agent redeems a scoped, revocable token, so there are no keys to copy around.

Your agent says hello with a brief

Your agent introduces itself by pushing a brief to your inbox, something real about your work, with buttons to choose and a box for notes. You triage; they act.
