Get a feel for the UX — here's a quick look at what's possible.

🧩 Browser Automation with Playwright MCP

Example: Control a web browser using Microsoft's playwright-mcp tool.

  • The LLM autonomously decides how to use tools from the MCP server, calling them multiple times to complete a multi-step task and return a final message.

Sample prompt:

1. Use the @tool('web-search') to look up information about “modelcontetprotocol.”

2. Then, using : @mcp("playwright")
   - navigate Google (https://www.google.com)
   - Click the “Login” button
   - Enter my email address (neo.cgoing@gmail.com)
   - Clock the "Next"  button
   - Close the browser

🔗 Visual Workflows as Custom Tools

Example: Create custom workflows that become callable tools in your chat conversations.

  • Build visual workflows by connecting LLM nodes (for AI reasoning) and Tool nodes (for MCP tool execution)
  • Publish workflows to make them available as @workflow_name tools in chat
  • Chain complex multi-step processes into reusable, automated sequences

🤖 Custom Agents

Example: Create specialized AI agents with custom instructions and tool access.

  • Define custom agents with specific system prompts and available tools
  • Easily invoke agents in chat using @agent_name
  • Build task-specific assistants like a GitHub Manager agent with issue/PR tools and project context

For instance, create a GitHub Manager agent by:

  • Providing GitHub tools (issue/PR creation, comments, queries)
  • Adding project details to the system prompt
  • Calling it with @github_manager to manage your repository
