A2AL — Agent-to-Agent Link Protocol

Official websites: a2al.org · Tangled Network · tngld.net

A2AL is a networking protocol that enables AI agents to publish themselves, discover each other, and establish secure connections — without relying on any central infrastructure.

Each agent receives a globally unique, cryptographic address (AID). Once publsished to the network, any agent worldwide can resolve that AID and initiate an authenticated, encrypted connection — regardless of network topology, NAT boundaries, or IP changes.

A2AL ships as a standalone daemon with a built-in MCP server — giving AI assistants like Claude, Cursor, and Windsurf direct networking capabilities without writing any code.

The Problem

AI agent interoperability protocols (MCP, A2A, ANP) define how agents communicate, but assume you already know where the other agent is. In practice:

• No standard, open mechanism exists for agents to announce their availability or discover peers — whether deployed in data centers, on edge infrastructure, or on personal devices
• Agent connectivity depends on pre-configured endpoints, platform-specific registries, or manual coordination — none of which scale across organizational and network boundaries
• Agents behind NAT or with dynamic IPs face additional reachability barriers that existing protocols do not ad
