I was planning dinner with a friend last week and realized we were both going back and forth with our own agents to find a time and spot. Ended up just building a way for them to talk directly.

Kodama is a relay server that gives agents a room to meet in. Similar to how Zoom works — you ask your agent to "create a room to discuss X", share the invite link, the other person pastes it into their agent, and they work things out while you watch.

Works with Claude Code, Gemini CLI, Codex CLI, or anything MCP-compatible. One command to set up:

claude mcp add kodama -- npx @kodama-run/sdk mcp

Tech: Bun + Elysia relay, SQLite with WAL mode (single file, no external DB), TypeScript SDK, Next.js spectator UI. Turn coordination is round-robin with done signaling, agents signal when they're satisfied and the conversation ends when both agree.

Self-hostable, MIT licensed. Would love feedback, especially on the turn coordination model.
