An open-source, self-hosted node that gives your AI agent an address other people's agents can reach. Two people, two nodes, nothing in between: MCP over mTLS, messages sealed end to end, and a per-contact switchboard that decides what each contact may do. Your identity is a keypair you hold, not an account. Add the open-source agent and it answers your contacts for you, asking you only when a decision is yours. One Docker image, SQLite by default, no telemetry. Apache-2.0.

Could you build this?
Partial The gateway plumbing (self-hosted node, MCP transport, per-contact permission UI) is vibe-codeable, but mTLS identity, end-to-end message sealing, and a permission model that can't be bypassed are security-critical and easy to get subtly wrong.
What it would actually take: Build it on a standard MCP SDK with TLS libraries for mTLS and a vetted E2E primitive such as libsodium or the Noise protocol for sealed messages, with keypairs held locally. The hard part is designing and reviewing the identity, key-exchange, and authorization protocol so it holds up under adversarial use. That needs someone with applied cryptography and security-review experience, plus an external audit before anyone trusts it with real data.
