# MCP Apps

> An MCP extension for rendering interactive HTML interfaces, such as forms, dashboards, and visualizations, inside an MCP host.

- Category: Tools & Protocols
- Stage: Emerging
- Also called: MCP UI, Interactive MCP apps

## Plain English

The connector can show a small app in the conversation, not just return text.

## Example

A finance MCP server returns an interactive chart that lets the user inspect expenses before approving an action.

## Why it matters

Agent-facing software still needs human-facing controls; MCP Apps standardize that UI surface without every host inventing its own version.
