Observability agents are fast. They query alerts, correlate logs with traces, and produce a root cause hypothesis in minutes. The part that still takes time is verification. You read the agent’s text summary, open your observability tools in a browser, navigate to the trace waterfall, check the service map to scope impact, and cross-reference what the agent told you against what you see on screen. The agent saved you the query time. It did not save you the tab-switching, context-carrying, manual-verification time. That is still your job.

Amazon OpenSearch Service MCP Apps close that gap. MCP Apps extend the Model Context Protocol so that each tool call responds with an interactive visualization — a trace waterfall, a service topology, a log pattern view — rendered directly in your AI assistant’s chat window alongside the text response. You ask the agent to investigate. The agent queries Amazon OpenSearch Service. The response arrives with both a text explanation and the relevant dashboard widget. You verify in the same thread where you asked the question, without opening a separate browser tab or re-running a query.

In this post, we explain how MCP Apps change your observability workflow and walk through setup step by step.
