An MCP server providing Playwright browser automation tools and a simple note storage system, enabling web interaction and data summarization.
This server offers useful browser automation but carries moderate risk. The ability to navigate to any URL and execute JavaScript introduces potential for malicious activity. Exercise caution when using Playwright tools with untrusted URLs or content. The note storage system itself poses a lower risk, but access should still be controlled.
Performance will depend on the complexity of the web pages being accessed and the efficiency of the Playwright scripts. Consider optimizing selectors and minimizing JavaScript execution.
Cost will primarily depend on the resources consumed by the Playwright browser and the frequency of API calls. Consider limiting the scope of web scraping and automation tasks.
npx @modelcontextprotocol/inspector uv --directory C:\Users\YUNYING\Documents\project\python\mcp\playwright-server run playwright-serverplaywright_navigateNavigates the browser to a specified URL.
Can be used to visit malicious websites.
playwright_screenshotTakes a screenshot of the current page or a specific element.
Screenshots can inadvertently capture sensitive information.
playwright_clickClicks an element on the page using a CSS selector.
Clicking elements is generally safe but could trigger unintended actions.
playwright_fillFills out an input field with a specified value.
Filling input fields could submit sensitive data or trigger unwanted actions.
playwright_evaluateExecutes JavaScript code in the browser console.
Arbitrary JavaScript execution can lead to code injection and other security risks.
playwright_click_textClicks an element on the page by its text content.
Clicking elements is generally safe but could trigger unintended actions.
playwright_get_text_contentGets the text content of all visible elements on the page.
Read-only operation, no side effects.
playwright_get_html_contentGets the HTML content of a specified element on the page.
Read-only operation, no side effects.

This server offers useful browser automation but carries moderate risk. The ability to navigate to any URL and execute JavaScript introduces potential for malicious activity. Exercise caution when using Playwright tools with untrusted URLs or content. The note storage system itself poses a lower risk, but access should still be controlled.
The server allows full read/write access by default. Exercise caution when granting autonomy, especially due to the JavaScript execution capability.
Production Tip
Implement robust input validation and output sanitization to mitigate risks associated with Playwright actions and JavaScript execution.
The documentation does not specify concurrency support. Testing is recommended to determine its behavior under load.
Error handling mechanisms are not explicitly documented. Implement your own error handling to ensure robustness.
There are no built-in mechanisms to restrict website access. Consider implementing a proxy or firewall for added security.
The documentation doesn't specify, but Playwright typically supports headless mode. Configuration may be required.
Use the Playwright tools to fill in login forms and submit them programmatically.
Rate limits are not documented. Be mindful of website terms of service and implement your own rate limiting if necessary.
The MCP Inspector is recommended for debugging. It allows you to step through code and inspect variables.
