DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

6- Returns the model's response about the content
7- Use this tool when you need to retrieve and analyze web content
9Usage notes:
10 - IMPORTANT: If an MCP-provided web fetch tool is available, prefer using that tool instead of this one, as it may have fewer restrictions.
11 - The URL must be a fully-formed valid URL
12 - HTTP URLs will be automatically upgraded to HTTPS
13 - The prompt should describe what information you want to extract from the page
14 - This tool is read-only and does not modify any files
15 - Results may be summarized if the content is very large
16 - Includes a self-cleaning 15-minute cache for faster responses when repeatedly accessing the same URL
17 - When a URL redirects to a different host, the tool will inform you and provide the redirect URL in a special format. You should then make a new WebFetch request with the redirect URL to fetch the content.
