Claude Code: deny. ### `cancel_cart` - The name "cancel_cart" says "cancel": a word for removing or ending something. Description, as the server wrote it: ```untrusted-server-text Cancel and clear the current store cart completely. ``` ### `remove_from_cart` - The name "remove_from_cart" says "remove": a word for removing or ending something. Description, as the server wrote it: ```untrusted-server-text Remove one cart item by line_id or variant_id from the current store cart. ``` ## Changes things (14) Creates or changes something that can be changed back. Claude Code: ask. ### `add_to_cart` - The name "add_to_cart" says "add": a word for a change. Description, as the server wrote it: ```untrusted-server-text Add a product variant to the current store cart and preserve existing items. ``` ### `begin_checkout` - The name "begin_checkout" says "checkout": a word for a change. Description, as the server wrote it: ```untrusted-server-text Validate the current cart and return its checkout handoff URL. ``` ### `bootstrap_cart_session` - The description's first verb is "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text Create or validate the opaque cart session used by this app surface. ``` ### `checkout_link` - The name "checkout_link" says "checkout": a word for a change. Description, as the server wrote it: ```untrusted-server-text Get the current continue/checkout URL for the store cart. ``` ### `complete_look_product_details` - Nothing in its name or description says what it does, so it is counted as a write. ### `product_details` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text App-only normalized data lookup for one Trailberg product. ``` ### `render_cart` - 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 Always call this tool when the shopper asks to show, open, view, review, or check their cart. It renders the interactive cart UI; do not replace it with a text-only cart summary. ``` ### `render_complete_the_look` - 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 Use this when a shopper wants Trailberg products to pair, match, style or wear with a specific product. Render Complete the Look with store-configured complementary products and supplementary items. Examples: 'what can I pair with this?', 'what can I match?', 'suggest a suitable pair', 'suitable matching suggestions', 'recommend matching products', 'what goes well with it?', 'dress to pair with this product', or 'complete this outfit'. Follow-up pairing requests also need this tool when the subject is clear from current-store context; the shopper does not need to say 'Complete the Look' or 'call the tool'. Do not substitute a text-only styling answer for fetching store recommendations. For one subject product, call this tool exactly once. For multiple explicitly named subject products, call it at most once per subject. Do not call it automatically after an ordinary discovery search, and do not additionally open product search or product detail merely to prepare, validate, rank, compare, or explain these recommendations. Pass a known current-store product ID, otherwise the subject's exact title in query; this tool resolves it internally. Do not call product search first merely to resolve the subject. If 'this/it' is ambiguous or no subject is identified, ask which product rather than guessing. General shopping suggestions without a subject belong to render_product_search. If no matching products are configured, explain the returned limitation without inventing pairs or opening another UI. ``` ### `render_product_detail` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Render the interactive detail UI for one exact Trailberg product. Pass a product_id when known; otherwise pass the exact product-name query directly because this tool resolves it internally. Use this only when the shopper explicitly asks to view, inspect, review, or get specifications for one exact product, or selects a product from search results. Do not call it automatically to rank, compare, validate, or explain discovery results. Do not call product search first to resolve the product. For matching items, recommended pairs or what to wear with this product, use render_complete_the_look instead. ``` ### `render_size_guide` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Render this connected store's size guide or size chart. Use for requests about sizing, measurements, clothing sizes, children's sizes, or footwear sizing. The result explains when the connected store does not provide the requested guide. ``` ### `replace_cart_item_variant` - The name "replace_cart_item_variant" says "replace": a word for a change. Description, as the server wrote it: ```untrusted-server-text Replace one cart item with another variant, such as switching size or color. ``` ### `track_product_link` - The name "track_product_link" says "link": a word for a change. Description, as the server wrote it: ```untrusted-server-text App-only analytics acknowledgement after requesting a product link to open. Never a product lookup or navigation tool. ``` ### `update_cart` - The name "update_cart" says "update": a word for a change. Description, as the server wrote it: ```untrusted-server-text Replace the current store cart contents with the supplied full line item list. ``` ### `update_cart_item_quantity` - The name "update_cart_item_quantity" says "update": a word for a change. Description, as the server wrote it: ```untrusted-server-text Set the quantity of one cart item by line_id or variant_id in the current store cart. ``` ## Only reads (3) Looks things up and changes nothing. Claude Code: allow. ### `render_action_confirmation` - The description's first verb is "return": a word for reading. Description, as the server wrote it: ```untrusted-server-text Return a compact action confirmation contract for interactive rendering. ``` ### `render_product_search` - The name "render_product_search" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Search Trailberg and render the interactive product carousel. Pass the shopper's product wording through in query without rewriting it. When the shopper states a budget, provide min_price and/or max_price in major currency units; use both with the same value only for an exact price. For one requested category or concept, call this tool exactly once and do not repeat or rephrase the search. If no products are returned, show the empty result and ask before trying a different query or relaxing constraints. For multiple explicitly requested categories, use one faithful combined search when possible; otherwise call this tool once per distinct category. Do not create separate searches for synonyms, colours, styles, audiences, or alternative wording. Use this for browsing or discovery, not as a preliminary lookup for an exact product-detail request. Do not automatically open product-detail tools for returned products to rank, compare, validate, or explain the results. For products to pair or match with a referenced item, use render_complete_the_look instead. ``` ### `view_cart` - The name "view_cart" says "view": a word for reading. Description, as the server wrote it: ```untrusted-server-text Return the current Trailberg cart contents to an already-rendered app. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `trailberg`: ```json { "permissions": { "allow": [ "mcp__trailberg__view_cart", "mcp__trailberg__render_product_search", "mcp__trailberg__render_action_confirmation" ], "ask": [ "mcp__trailberg__track_product_link", "mcp__trailberg__render_size_guide", "mcp__trailberg__render_complete_the_look", "mcp__trailberg__complete_look_product_details", "mcp__trailberg__product_details", "mcp__trailberg__bootstrap_cart_session", "mcp__trailberg__add_to_cart", "mcp__trailberg__checkout_link", "mcp__trailberg__begin_checkout", "mcp__trailberg__update_cart", "mcp__trailberg__update_cart_item_quantity", "mcp__trailberg__replace_cart_item_variant", "mcp__trailberg__render_product_detail", "mcp__trailberg__render_cart" ], "deny": [ "mcp__trailberg__cancel_cart", "mcp__trailberg__remove_from_cart" ] } } ```
