Adaptive Cards Mcp

If you're building Adaptive Cards for Microsoft 365, this server gives Claude the tools to generate, validate, and optimize them properly. It exposes nine operations including schema validation against the v1.6 spec, accessibility scoring, host-specific compatibility checks for Teams and Outlook, and data-to-card conversion that picks the right layout for your JSON or CSV. The optimize_card tool fixes common issues like missing wrap properties and alt text, while transform_card downgrades schema versions when you need v1.3 or v1.4 compatibility. It includes 21 preset patterns for approvals, notifications, and forms, plus templating support that converts static cards into reusable templates with expression bindings. Runs via npx with stdio transport, or as an HTTP/SSE endpoint for Copilot Studio integrations.
