How to Automate Browser Actions and External Tools from Cursor using MCPs

Learn how to configure Machine Control Protocols (MCPs) in Cursor to control external tools like a headless browser or a database directly from your IDE using natural language commands, effectively reducing context switching and manual work.

Step-by-Step Guide

1

Configure MCP Servers in Cursor

Navigate to Cursor's settings and add the necessary Machine Control Protocol (MCP) servers you want to use. The blog post mentions setting up servers for Browserbase (for web automation), Postgres (for database queries), and Stagehand.

2

Issue a Natural Language Command

In a Cursor chat window, simply write a plain-language command describing what you want to do with the external tool. For example, you can ask it to navigate to a website and take a screenshot.

Prompt:
navigate to chat p and take a screen grab
3

Observe the Automated Action

The AI in Cursor will interpret your command and use the configured MCP to control the external application. You can watch as the tool (e.g., a headless browser) executes the task you requested without you having to leave your IDE.

Pro Tip: While the example is simple, you can use this for more complex tasks like running automated front-end tests or querying a production database to verify data.
