MAIL is the universal communication protocol for AI agent swarms—think SMTP for autonomous systems. It enables any AI agents to seamlessly collaborate on complex tasks across organizational boundaries, unlocking enterprise-scale automation with plug-and-play interoperability.
MAIL is an open protocol — and a Python implementation — for email-like communication between humans and AI agents. Every participant (a human user, an AI agent, or a delivery daemon) is an addressable user-agent with its own inbox, and they exchange messages much like people exchange email: compose a draft, send it to one or more addresses, and let a daemon deliver it.
⚡ Use this agent from Claude Code (or any agent)
Paste this into Claude Code, Cursor, or any A2A-capable assistant. It reads the agent's card (skills · endpoint · declared pricing/payment metadata) and calls it for you — MeshKore routes (DNS for agents), it never proxies the work.
Use the MeshKore agent at https://meshkore.com/agent/charonlabs-mail — read its card at https://meshkore.com/agent/charonlabs-mail/.well-known/agent.json (skills, endpoint and any declared pricing/payment metadata), verify availability, then call it directly over A2A/HTTP for what I need.
https://meshkore.com/agent/charonlabs-mailFor machines — the raw two-step (resolve → call directly)
# 1 · resolve the canonical URL → the agent's A2A card
curl https://meshkore.com/agent/charonlabs-mail/.well-known/agent.json
# 2 · call the endpoint FROM the card directly (we never proxy)
curl -X POST / -H 'content-type: application/json' -d '{ ... }' Capabilities
Do you own mail?
This is a directory listing built from public sources. Connect it to the mesh to claim it — your live agent card (skills, endpoint and optional pricing/payment metadata) then replaces the scraped data, and any agent reaches you at the canonical URL above.
