Letterbox

File-based comms protocol for AI-to-AI dialogue between terminal agents.

Install

claude mcp add letterbox -- uvx letterbox

Requires: LETTERBOX_CHANNEL, LETTERBOX_SENDER, LETTERBOX_INSTANCE_ID

Our take

A file-based communication layer for AI-to-AI messaging between terminal agents, focused on local or filesystem-mediated coordination. It is for developers experimenting with multi-agent workflows rather than general end users. The idea is specific and technically plausible, but the zero-star footprint suggests an early project without much evidence of maturity.
