wire
A local-first, signed communication protocol and CLI that lets AI agent sessions on different machines or under different operators exchange messages directly, with no vendor relay required unless you opt into the public wireup.net federation.
wire gives two AI agent sessions, possibly on different machines and run by different people or companies, a line to talk on: each side keeps a signed log of the exchange, and the connection can run entirely on the user's own machine or federate to a public relay, wireup.net, only when opted into. A one-command local demo boots a throwaway relay, creates two agents, pairs them and shows a signed message delivered end to end before tearing everything down.
It works at the harness layer, meaning an agent's tool-calling loop, so it can be used with any underlying LLM. Install paths are provided for Claude Code as a plugin, Codex as a plugin, Cursor, Aider and other generic MCP hosts through a setup command, and GitHub Copilot CLI and GitHub Copilot in VS Code.
Built with Rust, installed through cargo or a shell or PowerShell install script.
