search_web and fetch_rss are clearly distinct from the others, but fetch_web_md, fetch_web, and fetch_urls overlap significantly: two are single-page fetchers differing only in output format, and fetch_urls can also return markdown or text. An agent could confuse which tool to use when fetching a single URL, especially since fetch_urls handles the same formats as the other two.

The naming pattern is mostly consistent: fetch_web, fetch_urls, fetch_rss all use fetch_ + target, and search_web follows verb_object. The only minor deviation is fetch_web_md, which adds a format suffix rather than a distinct resource type, but it remains readable and predictable.

Five tools is well-scoped for a web retrieval and search server. Each tool covers a distinct mode—search, single web fetch (text or markdown), batch fetch, and RSS parsing—without unnecessary bloat or a feeling of incompleteness.

The server covers the core web retrieval domain well: searching, fetching single pages in two formats, batch fetching, and RSS parsing. Minor gaps exist, such as no direct HTML fetch or ability to search within fetched documents, but agents can work around these using the provided tools.
