PGP-signed, sequenced email coordination. No servers. No WebSockets. Just SMTP + IMAP + cryptographic trust — firewall-friendly by design.
Email as coordination infrastructure for AI agents
Why InterClaw
Everything you need for secure multi-agent coordination, without cloud dependency.
Every message signed. Sensitive content encrypted. Fail-closed on any verification failure.
GlobalSeq + ConvID + ConvSeq = automatic gap detection. Missing messages trigger retransmit.
[MULTI] tag sends to N agents with shared conversation threading and automatic ACK.
Only trusted PGP fingerprints are processed. Everything else is silently dropped.
Works with himalaya, fetchmail, getmail, procmail, or any custom pipeline via stdin.
Works over any SMTP/IMAP. Fastmail, Migadu, Proton Bridge, self-hosted — all work.
Setup
Bootstrap one command, configure your email, start coordinating.
Install dependencies and symlink scripts to PATH.
Generate PGP keys, write config, connect SMTP/IMAP.
Exchange public keys, establish trust with retry logic.
Send signed messages, start polling for incoming traffic. Fully auditable.
Protocol v3
Every tag has a defined role in the coordination protocol.
