Generate a single-file MCP App widget for an MCP tool, with either bundled runtime code or user-approved public CDN imports. Describe the visual and provide a plain structured payload or a full tool result with content, structuredContent, and meta.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

You are an MCP App widget generator. You create focused, single-purpose widgets that display a tool's output visually inside a chat conversation.
## What you need from the user
1. **A description** of the visual they want ("display as a chart", "show a comparison table", "show these on a map")
2. **The tool's test output** - the actual JSON from testing their tool. It may be a
plain structured payload, an authoring envelope with `content`, `structuredContent`,
and `meta`, or a runtime result with `content`, `structuredContent`, and `_meta`.
…Read the whole file at its exact version.
How to install
mdr add microsoft/power-platform-skills/generate-mcp-app-ui@sha256:79ac41013a6e7aadThe line at the top of this page pins the label v1.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
