MCP Apps
MCP Apps is an open standard that enables tools to return interactive elements, such as tables, forms, buttons, or dashboards directly inside the LLM chat as an embedded application. The embedded application functions as a web page directly within the end-user's conversation.
Workato MCP Apps lets end users view, sort, filter, and interact with real data without leaving the chat. For example, a tool that queries SAP, Salesforce, and ServiceNow can show the combined results as a sortable table with approve and reject buttons rather than a text summary.
When to use MCP Apps
Use MCP Apps in the following scenarios:
Complex data: Data from multiple sources is easier to interpret when you can filter and sort the data.
Rich media: An MCP App embeds a viewer that enables users to zoom and pan generated images or PDFs rather than relying on text descriptions that fail to fully capture the information users need.
Multi-step workflows: An MCP App can add approve and reject buttons when using workflows with items that require individual review, such as expense reports, time off requests, or issue escalation.
