SLM Mesh is an open-source MCP server that gives AI coding agents peer-to-peer communication. SLM Mesh fixes this with 8 MCP tools: - Peer discovery (scoped by machine, directory, or git repo) - Direct messaging + broadcast - Shared key-value state - File locking with auto-expire - Event bus for real-time coordination Works with Claude Code, Cursor, Aider, Windsurf, Codex, VS Code — any MCP-compatible agent. npm install -g slm-mesh
Hi PH! I'm Varun, and I built SLM Mesh because I was tired of being the message bus between my AI coding sessions.
The core insight: every AI coding agent (Claude, Cursor, Aider) has isolated sessions. When you run 3+ in parallel, they have no way to coordinate. You end up copy-pasting context between terminals.
SLM Mesh adds 8 MCP tools that let agents discover each other, send messages, share state, and lock files. It works with ANY MCP-compatible agent, not just one vendor.
Technical highlights:
- SQLite + WAL mode for persistence
- Unix Domain Sockets for <100ms push delivery
- Bearer token auth on every endpoint
- 480 tests, 100% line coverage
- Auto-start broker, auto-shutdown when idle
MIT licensed. Would love your feedback.

I'm curious, is this different than having Claude Code spawn a team of agents?
