  • AG-UI is an open-source protocol that completes the agent protocol stack, following MCP and A2A
  • Enables real-time interaction between users and agents across apps like shopping, support, and crypto

[Unblock Media] AG-UI (Agent Gateway User Interface) is emerging as the final missing piece in the agentic computing stack. While MCP connects agents to tools, and A2A enables agent-to-agent communication, AG-UI directly links agents with users in real time. [object Object]

When a user sends a POST request to an agent endpoint, a single HTTP stream is opened. The agent then streams events, each containing a type and metadata, and the UI updates the moment each event is received. UI can also send back context or user actions to the agent, enabling true bi-directional communication.

For instance, on a shopping site, clicking “Check Order History” sends a request to the agent, which returns the order status that updates the UI instantly. This architecture delivers faster, more agent-centric synchronization than traditional static API calls.

AG-UI integrates smoothly with frontend frameworks like React, Vue, Svelte, and Next.js. With WebSocket or SSE listeners, developers can bind real-time responses directly to UI components. In support systems, agent-generated replies can appear instantly in the user’s view.

The protocol also brings significant potential to blockchain applications. For example, if a user sends crypto from their wallet, AG-UI passes this request to an agent, which monitors the blockchain and reflects the status change (e.g., Pending → Confirmed) live in the interface. This real-time sync is ideal for DeFi apps, NFT marketplaces, and token dashboards.

Technically, AG-UI supports integration with GraphQL, JSON-RPC, Web3.js, Ethers.js, and subgraph-based indexing systems, enabling responsive UI behavior across decentralized networks.

As an open-source project, AG-UI is freely available for developers to integrate and extend. It signals a new paradigm in how user interfaces and autonomous agents interact.
