# HAIP 1 archive — Human-Agent Interaction Protocol

> Historical HAIP 1 documentation. Unsupported and incompatible with HAIP 2.

<Warning>
  **Unsupported HAIP 1 archive.** This is historical chat and streaming documentation, not the HAIP 2 review protocol. Its APIs, package examples and security advice must not be used for a HAIP 2 deployment. Start with the [current HAIP 2 guides](/index).
</Warning>

## What is HAIP?

The Human-Agent Interaction Protocol (HAIP) is an open standard designed to streamline real-time, multi-modal exchanges between user-facing web, mobile, and voice applications and AI agents. It complements the Model Context Protocol (MCP): HAIP focuses on the human-agent layer, acting as a universal translator between frontend interfaces and intelligent backends, while MCP governs tool execution.

### Features

* Re-establishing dropped connections & ensuring message order.
* Multimodal transactions audio and text.
* Allowing multiple users and LLMs to share a conversation (transaction).
* Letting the user know about MCP (Model Context Protocol) calls.
* Transaction history, transaction management, schema validation, custom tooling, logging, authentication and more.
