Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.
How agent discovery & health will work →About
Copy/paste React components for rendering tool calls in AI chat interfaces. Built by assistant-ui.
Docs · Gallery · Quick Start
When a model calls a tool, most apps dump raw JSON into the conversation. These components turn tool payloads into interactive UI like approvals, forms, tables, charts, and media cards so users can understand and act without leaving the chat.
Featured Components
Option List Let users select from multiple choices
Question Flow Multi-step guided questions with branching
Why Tool UI?
- Copy/paste, not install — shadcn/ui model. Components live in your codebase. No dependency lock-in.
- Schema-validated — Every component has a Zod schema. Parse tool output, render when valid, fail safely when not.
- Interactive with receipts — Components aren't just displays. Users make choices that flow back to the assistant. Choices persist as receipts.
- Built on shadcn/ui — Radix primitives, Tailwind styling, your theme. No new design system to learn.
