What it does
MCP UI allows MCP servers to deliver interactive web components directly to a client. Instead of plain text, servers can send UIResource payloads (HTML, URLs, or Remote DOM scripts) that the client renders in a sandboxed iframe, enabling dynamic dashboards, interactive forms, and rich visualizations within the AI chat interface.
Key features
- Multi-Transport Rendering: Supports inline HTML, external URLs via
text/uri-list, and high-fidelity Remote DOM scripts. - Bi-directional Interaction: UI components can trigger tool calls, intents, or notifications back to the AI agent via the
onUIActionevent. - Cross-Language Support: Provides full SDKs for both TypeScript and Ruby.
- Sandboxed Execution: Ensures security by rendering all remote content within isolated iframes.
