Stop copy-pasting context between coding agents.
Agent Bus MCP gives Codex, Claude Code, Gemini CLI, OpenCode, Cursor, and other MCP-capable tools one durable local inbox for handoffs, reviews, and sidecar work. Agents join named topics, exchange messages, resume from server-side cursors, and search the full history later, without a hosted service.
Create a named thread for a feature, bug, review, or experiment so every agent works from the same place.
Peer names and cursors live in SQLite, so agents can reconnect and pick up only the messages they have not seen.
Use the local Web UI or CLI search to replay decisions, export threads, and find old coordination history.
Start with the workflow you need.
Try a two-agent handoff first, then install Agent Bus MCP in your own clients. Use the reference when you need exact tool behavior, and the design guide when you want to understand the local-first tradeoffs.
Walk through two agents joining the same topic, exchanging messages, and replaying the result.
Add the MCP server to your clients and point them at the same local database.
Find exact MCP tools, CLI commands, environment variables, and behavior.

Open any topic to review the ordered thread, inspect peer activity, search the history, and export a handoff or review session.
