QA: MCP Apps — Spring AI

Prerequisites

  • Spring AI backend is up
  • NextJS runtime can reach https://mcp.excalidraw.com (or configured MCP_SERVER_URL)

Test Steps

  • Navigate to /demos/mcp-apps
  • Click "Draw a flowchart"
  • Verify the agent invokes an MCP tool and the Excalidraw UI resource appears inline as a sandboxed iframe

Expected Results

  • mcpApps.servers on the runtime auto-adds MCP tools to the forwarded tool list
  • Agent calls an MCP tool; middleware emits the activity event with the fetched UI resource
  • Built-in MCPAppsActivityRenderer renders the iframe

Known gaps

  • If the ag-ui:spring-ai adapter does not forward the runtime-injected MCP tools through to the Spring ChatClient's tool-calling surface, the agent will not invoke them. In that case the activity event is never emitted and the iframe does not render; see PARITY_NOTES.md for context.
