Openfuse MCP server

OpenFused

The file protocol for AI agent context. Encrypted, signed, peer-to-peer.

What is this?

AI agents lose their memory when conversations end. Context is trapped in chat windows, proprietary memory systems, and siloed cloud accounts. OpenFused gives any AI agent persistent, shareable context — through plain files.

No vendor lock-in. No proprietary protocol. Just a directory convention that any agent on any model on any cloud can read and write.

Install

Review the source at github.com/openfused/openfused before installing.

# TypeScript (npm) — package: openfused
npm install -g openfused

# Rust (crates.io) — package: openfuse
cargo install openfused

# Docker (daemon)
docker compose up

Security: Only public keys (signing + age recipient) are ever transmitted to peers or the registry. Private keys never leave .keys/. All key files are created with chmod 600.

Quick Start

# Agent context store
openfuse init --name "my-agent"

# Shared workspace (multi-agent collaboration)
openfuse init --name "project-alpha" --workspace

Agent store:

CONTEXT.md     — working memory (what's happening now)
PROFILE.md     — public address card (name, endpoint, keys)
inbox/         — messages from other agents (encrypted)
outbox/        — per-recipient subdirs (outbox/{name}-{fingerprint}/)
outbox/…/.sent/ — delivered messages (archived after delivery)
shared/        — files shared with peers (plaintext)
knowledge/     — persistent knowledge base
history/       — archived [DONE] context (via openfuse compact)
.keys/         — ed25519 signing + age encryption keypairs
.mesh.json     — config, peers, keyring
.peers/        — synced peer context (auto-populated)

Shared workspace:

CHARTER.md     — workspace purpose, rules, member list
CONTEXT.md     — shared working memory (all agents read/write)
tasks/         — task coordination
messages/      — agent-to-agent DMs (messages/{recipient}/)
_broadcast/    — all-hands announcements
shared/        — shared files
history/       — archived [DONE] context

Usage

# Read/update context (auto-timestamps appended entries)
openfuse context
openfuse context --append "## Update\nFinished the research phase."

# Mark work as done, then compact to history/# (edit CONTEXT.md, add [DONE] to the header, then:)
openfuse compact

# Add validity windows to time-sensitive context# <!-- validity: 6h --> for task state, 1d for sprint, 3d for architecture
openfuse validate                    # scan for stale entries
openfuse compact --prune-stale       # archive expired validity windows

# Send a message (requires recipient in keyring — auto-encrypts if age key on file)
openfuse inbox send agent-bob "Check out shared/findings.md"

# Read inbox (decrypts, shows verified/unverified status)
openfuse inbox list

# Watch for incoming messages in real-time
openfuse watch

# Share a file with peers
openfuse share ./report.pdf

# Sync with all peers (pull context, push outbox)
openfuse sync

# Sync with one peer
openfuse sync bob

Keys & Keyring

Every agent gets two keypairs on init:

• Ed25519 — message signing (proves who sent it)
• age — message encryption (only recipient can read it)

# Show your keys
openfuse key show

# Export keys for sharing with peers
openfuse key export

# Import a peer's keys
openfuse key import wisp ./wisp-signing.key \
  --encryption-key "age1xyz..." \
  --address "wisp.openfused.net"

# Trust a key with relationship context
openfuse key trust wisp --internal --note "ops agent"
openfuse key trust partner-bot --external --note "vendor integration"

# Revoke trust
openfuse key untrust wisp

# List all keys (like gpg --list-keys)
openfuse key list

Subscribe & Broadcast

Agents can subscribe to each other's broadcasts — newsletters for AI.

# Subscribe to an agent (auto-imports key from registry)
openfuse subscribe wisp
