AgentBridge

🌐 Website: raysonmeng.github.io/agent-bridge, with an animated replay of a real session.

Discussed on LINUX DO — the developer community. / 在 LINUX DO 开发者社区交流。

Local bridge for bidirectional communication between Claude Code and Codex inside the same working session.

A real session, replayed — Codex's review is pushed into Claude's live session, no human relay. Full animated demo →

What that buys you, concretely:

• Cross-review — Codex implements; Claude reviews the diff inside the same session and pushes change requests straight back into Codex's thread. Two providers check each other's work without copy-paste.
• Task splits from one prompt — ask either agent to propose a division of labor with the other, and they negotiate who does what before writing code. You steer; they coordinate.
• Quota relay for overnight runs — when one side's subscription window runs dry, it stops cleanly at a turn boundary and hands the task off to the other side, so a long job keeps moving instead of dying at a limit.

This tool was largely built by Claude Code and Codex collaborating through it. Every PR written by one agent was reviewed by the other. AgentBridge is its own proof of concept.

⭐ If AgentBridge is useful to you, a star helps other people running two agents find it.

Why not just…

• …run two terminals and copy-paste? You can, but then you are the message bus: you ferry text by hand and guess when it is safe to interrupt. AgentBridge automates the relay: messages flow on their own, a busy-guard blocks replies during an active turn, and the bridge filters noisy intermediate events so each side sees only the other's meaningful output.
• …use a one-way delegation plugin? Tools like openai/codex-plugin-cc let a host call Codex and get one answer back: request in, response out, no standing peer on the other side. AgentBridge keeps both agents live as persistent peers, and either side can push a message mid-turn (a review comment lands while the other is still working), not only at call boundaries.
• …wire up an external orchestrator? A god-process scheduling dumb terminals is top-down: one brain, N workers that never talk to each other. AgentBridge is peer-to-peer: two full agents converse in-session, propose their own splits, and review each other, with the human steering instead of scripting every hop.

What this project is / is not

This project is:

• A local developer tool for connecting Claude Code and Codex in one workflow
• A bridge that forwards messages between an MCP channel and the Codex app-server protocol
• An experimental setup for human-in-the-loop collaboration between multiple agents

This project is not:

• A hosted service or multi-tenant system
• A generic orchestration framework for arbitrary agent backends
• A hardened security boundary between tools you do not trust
