Changes things 3Claude Code: ask
check_changeDid this web page change since the last time it was checked?No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it Did this web page change since the last time it was checked? Hash-based change detection. First check reports 'new'; later checks report 'changed' or 'unchanged'.
check_linkIs this URL live right now?No findings
Why it is in this group
- The name "check_link" says "link": a word for a change.
Description, as the server wrote it Is this URL live right now? Returns HTTP status, the redirect chain, final URL, and round-trip latency in milliseconds.
verifyDoes this source URL support a given claim?No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it Does this source URL support a given claim? Returns a confidence score, matched terms, and the best supporting excerpt. Heuristic term-overlap — not semantic fact-checking.
Only reads 1Claude Code: allow
fetchGet clean, readable text from a web page — boilerplate, navigation, and ads stripped — so you can work with the actual content.No findings
Why it is in this group
- The name "fetch" says "fetch": a word for reading.
Description, as the server wrote it Get clean, readable text from a web page — boilerplate, navigation, and ads stripped — so you can work with the actual content. Returns the text plus title, content-type, HTTP status, and length.
This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
