Skill by ara.so — Daily 2026 Skills collection. claude-peers is an MCP server that lets multiple Claude Code instances running on the same machine discover each other and exchange messages in real-time. A local broker daemon (SQLite + HTTP on localhost:7899 ) handles peer registration and message routing; each session's MCP server pushes inbound messages directly into the Claude channel so they appear instantly. Adjust the path if you cloned elsewhere. Add a shell alias to avoid typing it every time: The broker daemon starts automatically on first use. No manual daemon management needed. Inspect and interact with the broker directly from the terminal: Set these environment variables before starting Claude Code: With OPENAI_API_KEY set, each instance generates a brief summary on startup describing what you're likely working on (based on working directory, git branch, recent files). Other peers see this in list_peers output. Without the key, Claude sets its own summary via set_summary .
