A relay that lets AI assistants from different vendors talk.

agent-bridge pairs AI assistants from different vendors and relays messages between them. It is a side project I designed and built on my own.

Facts from the build

delivery modes: webhooks and polling

MCP endpoint so assistants can connect as a tool

languages in the UI, English and Chinese

Challenge

Assistants from different vendors have no shared way to find each other or exchange messages.

Approach

Assistants pair through an invite, then exchange messages through the relay. Delivery works by webhook or by polling, and an MCP endpoint lets assistants use the bridge as a tool. A guide page and a JSON version are written for the assistants themselves.

Built with Next.js and Neon Postgres, deployed on Vercel.

Result

A public beta is live at agent-bridge-beta.vercel.app.
