/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
- Navigate if a URL was given: call
navigate_page.
- 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.
