/firefox-devtools-mcp:screenshot

Captures a screenshot of a URL or the current page and shows it to the user.

Usage

/firefox-devtools-mcp:screenshot https://example.com   # Navigate then screenshot
/firefox-devtools-mcp:screenshot                       # Screenshot current page
/firefox-devtools-mcp:screenshot <uid>                 # Screenshot specific element

Steps

1. Navigate if a URL was given: call navigate_page.
2. Take the screenshot using the method that matches your environment:

In Cowork (system prompt contains an outputs folder host path under "Shell access"):

• Call screenshot_page saveTo="<host-outputs-path>/screenshot.png" using the host path from the system prompt, not the container path.
• Load and call present_files with that same path so the user receives a clickable file card.

In Claude.ai chat or Claude Desktop (no outputs folder in system prompt):

• Call screenshot_page without saveTo.
• Your final response must include the actual image returned — not a description of it. The user cannot see tool call outputs, only what you include in your reply.
