Claude Code: ask. ### `publish_card` - The name "publish_card" says "publish": a word for a change that another call does not undo. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text One promotion ready to publish elsewhere: the card as a picture (PNG, the same card the site's share button makes: store, photo, title, what you pay, regular price, label, end date; square by default, or 4:5 feed, 9:16 story, 1200x630 link preview; four designs: a shelf tag, b till receipt, d large photo, f 'Vandaag €x goedkoper' with the price large), a short link dealio.be/l/ that counts the click and sends the reader straight to the store's page, the store's page itself, the dealio link and a caption. Use the id from search_deals or get_deal. ``` ## Changes things (2) Creates or changes something that can be changed back. Claude Code: ask. ### `get_campaigns` - The name "get_campaigns" says "get": a word for reading. - The description's first verb is "store": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text The store campaigns (winkelacties) running at Belgian retailers, as read from the stores' own sites (dealio.be/acties/): a percentage on a whole range, brand or store, multi-buy (1+1, 2e halve prijs), cashback from the maker, a voucher, a gift, free delivery, loyalty-card deals, sales, no VAT, and announced ones. Not one product's price (that is search_deals). Each with store, kind, the advantage in a few words, what it applies to, condition, code, validity, whether it works on products or on the whole basket, dealio's link, and the promotions on dealio that fall under it (with their links). Filter by store, kind or words. ``` ### `list_stores` - The name "list_stores" says "list": a word for reading. - The description's first verb is "store": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text The stores in the data: slug, name, number of current promotions, the median discount per item where known, when the store was last fetched, and the pages of the store and its weekly overview. Also lists the category slugs. ``` ## Only reads (6) Looks things up and changes nothing. Claude Code: allow. ### `get_buying_guide` - The name "get_buying_guide" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text A researched buying guide (koopwijzer) for a kind of product, e.g. 'airfryer': the models compared (key specs, today's lowest promotion), what each feature does, when you need it and when not, and general facts, every statement with its source. Use it for 'best ' and 'which should I buy' questions ('beste airfryer', 'welke wasmachine kopen'): it does not crown a winner, it gives the cited test and buyer scores with their sources. Without a type: the list of guides. ``` ### `get_deal` - The name "get_deal" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text One promotion in full, by the id a search result gave. ``` ### `get_meal_ideas` - The name "get_meal_ideas" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Meal ideas from the promotions (kookinspiratie): the dishes whose main ingredients are all in promotion at the given Belgian food store(s) on the day the user shops, with those promotions (price, deal, until when, link), the side ingredients that are in promotion too, and what else is needed that is not. Dish ideas for a shopping list, not recipes. Without stores: per food store how many dishes its promotions make today. ``` ### `get_model` - The name "get_model" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text One model from a buying guide in full: the maker's specs, what tests and buyers say (score, summary, pros, cons, source), facts, and today's promotions for it with their links. ``` ### `get_news` - The name "get_news" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Belgian consumer news for people who want to save (dealio.be/nieuws/): prices, promotions, store openings and incidents, product recalls (FAVV), tests (Test-Aankoop), taxes and energy, summarised by dealio in two or three sentences with our own headline, the source and the link to its article, newest first. Filter by store (name or slug) or theme. Each item has dealio's link (the item on the news page) and the store pages it names. ``` ### `search_deals` - The name "search_deals" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Search the current promotions at Belgian retailers by product, brand or store, with optional filters. Returns the best matches (biggest per-item discount first unless sorted otherwise), each with price, discount, validity and a link to open it. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `deals`: ```json { "permissions": { "allow": [ "mcp__deals__search_deals", "mcp__deals__get_deal", "mcp__deals__get_buying_guide", "mcp__deals__get_model", "mcp__deals__get_meal_ideas", "mcp__deals__get_news" ], "ask": [ "mcp__deals__list_stores", "mcp__deals__publish_card", "mcp__deals__get_campaigns" ], "deny": [] } } ```
