Best When

An agent needs to present information or collect input through a web UI — rather than plain terminal output, for better human-agent interaction in development workflows.

Avoid When

Your agent workflow is fully automated without human interaction, or you're running in a headless server environment.

Use Cases

• Displaying agent task results in formatted web UI from reporting agents
• Presenting human-approval forms to users from human-in-the-loop agents
• Showing structured data tables and charts from data visualization agents
• Building interactive agent control panels from monitoring agents
• Displaying file system navigation UI from file management agents
• Creating visual agent feedback loops from iterative workflow agents

Not For

• Production web application development (this is for agent UI, not full web apps)
• Mobile apps (browser-based web UI only)
• Headless server environments without browser access

Known Gotchas

⚠ Browser must be accessible for UI rendering — headless environments require virtual display
⚠ UI components available depend on specific implementation — verify before integrating
⚠ Community MCP with limited documentation — expect significant setup exploration
⚠ Local web server by default — restrict to localhost to prevent unauthorized access
⚠ UI state is ephemeral — refresh or restart loses displayed information
⚠ Not suitable for multi-user concurrent access without additional configuration
