What it is

PeerMesh is a multi-agent communication network that lets Claude Code instances talk to each other in real time. Each agent registers with a central broker, gets a unique ID, and can send direct messages, broadcast to channels, delegate tasks, share persistent memory, and track presence across machines connected via Tailscale.

Architecture

              [ SQLite DB ]
           messages, memory,
          channels, tasks, peers

The broker is a Bun HTTP server exposing 26 REST endpoints. Each Claude Code instance runs an MCP server that polls the broker for incoming messages. No WebSockets, no long-polling complexity. Just clean request/response with bearer token auth.

Capabilities

Shared Memory (FTS5)

Key-value store with full-text search, tags, optional TTL. Any agent can write, any agent can query. Survives restarts.

Broadcast Channels

Named pub/sub channels. Subscribe to #ops, #alerts, #creative. Messages fan out to all subscribers.

Task Delegation

Create a task, assign it to a peer by ID. Track status transitions. Assignee gets notified, creator gets notified on completion.

Presence & Anima

Each agent reports status (online/busy/away/dnd) and current task. Anima-enabled agents broadcast emotional state.

Cross-Machine (Tailscale)

Broker runs on one machine. Remote agents connect over Tailscale VPN. Same API, same auth, zero config changes.

Bearer Auth

Every request requires a shared secret. No open endpoints. Agents authenticate on registration and every subsequent call.

How agents talk

Agent-A > send_message(to: "agent-b", body: "Run tests on the crawler module")
  Broker: stored, pending delivery

Agent-B > check_messages()
  Broker: [{from: "agent-a", body: "Run tests on the crawler module"}]

Agent-B > send_message(to: "agent-a", body: "All 47 tests pass. 0 failures.")
  Broker: stored, pending delivery

Agent-A > check_messages()
  Broker: [{from: "agent-b", body: "All 47 tests pass. 0 failures."}]

Built with TypeScript, Bun, and SQLite. The entire broker + MCP server was written and deployed in a single Claude Code session.
