Unison Protocol

What it does

Unison Protocol is a high-performance communication framework that uses QUIC and KDL schemas to ensure type-safe interactions between clients and servers. It treats every interaction as a 'channel', supporting request-response, event pushing, and raw byte streams over a single bidirectional connection.

Tools

• open_channel: Establishes a specialized communication stream for a specific namespace.
• request: Sends a type-safe request and awaits a response via the Unison frame format.
• send_event: Pushes an asynchronous event to the connected peer.
• send_raw: Bypasses serialization for high-efficiency data transfer (e.g., audio/binary).

Installation

To integrate as an MCP server, use the unison-agent crate:

{
  "mcpServers": {
    "unison": {
      "command": "cargo",
      "args": ["run", "-p", "unison-agent"]
    }
  }
}

Supported hosts

Confirmed for Claude Agent SDK and various Rust-based agent environments.
