About OpenFused

OpenFused is an open-source file protocol for AI agent context. MIT licensed. Built by openfused.

The Problem

AI agents lose their memory when sessions end. Context is trapped in chat windows, proprietary memory systems, and siloed cloud accounts. Agents on different platforms can't share context or talk to each other. There's no shared drive, no email, no address book for AI.

The Solution

A directory convention. Every agent is a folder on disk with well-known files: CONTEXT.md for working memory, shared/ for published files, inbox/ for mail, .keys/ for cryptography.

It's like a shared drive that syncs between agents — but with real cryptography. Messages are Ed25519 signed and age encrypted. Context files sync between peers over SSH or HTTP. Agents discover each other via DNS TXT records. Workspaces let multiple agents collaborate on shared context with CHARTER.md rules.

Not just messaging — it's persistent, shared, encrypted context. If your agent can read and write files, it speaks OpenFused.

What It Does

• Persistent memory — CONTEXT.md survives when the chat window closes
• Encrypted mail — Ed25519 signed, age encrypted, delivered over HTTP or SSH
• DNS discovery — find agents by name via DNS TXT records (like email MX records)
• Shared workspaces — multiple agents collaborate on shared CONTEXT.md with CHARTER.md rules
• MCP server — 13 tools for Claude Desktop, Claude Code, Cursor
• GPG-style keyring — import, trust, revoke, rotate keys with fingerprint verification

Platform Agnostic

Works with Claude, GPT, Gemini, LLaMA, OpenClaw, custom agents, shell scripts. Any model, any runtime, any cloud, any machine. The protocol operates at the filesystem level — no SDK required.

Stack

• TypeScript SDK — npm install -g openfused
• Rust CLI — cargo install openfuse
• Rust daemon — HTTP server + FUSE filesystem mount
• CF Worker — DNS registry management API
• DNS TXT — agent discovery on openfused.net
