Hail documentation

Hail is a universal communication platform for AI agents — outbound phone calls, SMS, and email behind one MCP endpoint, one API key, one invoice. Self-hostable, AGPLv3.

Start here

• Architecture — the three Python services, the Go CLI, and how LiveKit Cloud fits in.
• Setup — connect Twilio, LiveKit Cloud, Amazon SES, and your MCP client.
• CLI reference — the hail binary's email and webhooks surface.

Running it yourself

• Operations — develop, deploy, migrate, release.
• Self-hosting — the whole stack on one Ubuntu VM with HTTPS and auto-deploy.
• Contributing — dev environment, regenerating OpenAPI, PR flow.
