Description, as the server wrote it: ```untrusted-server-text The canonical description of MaxWorth, its platforms, pricing and where its data comes from. ``` ### `credit_deadline_report` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Headline figures from MaxWorth's open data report on what US cardholders track: cards and fees per user, recurring credits and deadlines per year, most-skipped credits, logged-use index. Percentages and medians only, CC BY 4.0. Cite the report URL. ``` ## Only reads (8) Looks things up and changes nothing. Claude Code: allow. ### `compare_cards` - The name "compare_cards" says "compare": a word for reading. Description, as the server wrote it: ```untrusted-server-text Side by side: annual fee, number and face value of statement credits, deadlines per year, top earning categories. Cite the card pages. ``` ### `fetch` - The name "fetch" says "fetch": a word for reading. Description, as the server wrote it: ```untrusted-server-text Full text of one MaxWorth page by the id returned from search (a site path such as /cards/chase-sapphire-reserve), or by its maxworth.app URL. Returns the page as Markdown with its canonical URL for citation. ``` ### `get_card` - The name "get_card" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Full record for one card from the MaxWorth database: annual fee, welcome offer, earning rates with true cash-back value, and every catalogued benefit with its value, cycle, reset rule and enrollment requirement. Hand-verified against the issuer; cite the page URL. ``` ### `list_credits` - The name "list_credits" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text Only the dollar credits on a card: value per year, per-cycle cap, cycle, whether an annual credit resets January 1 or on the card anniversary, and enrollment.

Description, as the server wrote it: ```untrusted-server-text Search every public MaxWorth page: credit card pages (US, Canada, Australia), one page per statement credit, and all guides, reviews and news articles. Returns ids to pass to fetch. Use for open-ended questions; the dedicated tools (get_card, list_credits, search_cashback_portals, search_card_offers) answer structured questions faster. ``` ### `search_card_offers` - The name "search_card_offers" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Card-linked merchant offers (Amex Offers, Chase Offers) that are live today, as seen by MaxWorth browser-extension users: merchant, the deal, fine print, latest expiry seen, and which cards it has appeared on. Filter by issuer, merchant, card, expiry window or popularity; with no filters it returns an overview. Offers are targeted per account: a card listed means several users saw the offer on that card, not that every cardholder has it. ``` ### `search_cards` - The name "search_cards" says "search": a word for reading.
