MCP UI integration pattern - tools that return pre-formatted UI content

General

Hi Agno team!
I’m implementing an MCP UI integration pattern where MCP tools return pre-formatted UI content (HTML or JSON) that should be rendered directly by the client UI.

I’m using AgUI as my front-end framework, and I’d like advice on the most suitable approach to handle this pattern. Specifically:

  • How should MCP tools structure their output so AgUI can safely and consistently render it?

  • Is there a recommended schema or wrapper format for returning UI-ready HTML/JSON from MCP tools?

  • Should the client implement a custom renderer, or does AgUI provide an existing pattern for interpreting these responses?

  • Any best practices or examples for securely rendering HTML returned by MCP tools?

Would appreciate any guidance or reference implementations.
Thanks!
