Claude Code: ask. ### `recommend_products` - 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 Recommend catalog products for a need described in plain language. FREE. Typical input {"need": "help answering customer support emails"} returns {"need": ..., "recommendations": [{"slug": ..., "name": ..., "why": ..., "area": ..., "try_free": ""}], "next": "..."}. Use when the caller describes a problem instead of naming a product; ranking is by fit to the described need. Not for exact keyword or slug lookups (search_catalog). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": ""}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry. ``` ## Only reads (9) Looks things up and changes nothing. Claude Code: allow. ### `get_free_skill` - The name "get_free_skill" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Load a product's free gateway skill with its complete instructions. FREE. Typical input {"slug": "inbox-zero-assistant"} returns {"slug": ..., "skill": "", "instructions": ""}. Returns exactly one skill - the product's free gateway skill - chosen automatically from the slug, with no plan required. Use when the caller wants usable instructions immediately. Not for the product's other skills: those are named and need get_full_skill with a skill_name, which requires a paid plan. Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": ""} (for example {"error": "unknown slug ''"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry. ``` ### `get_full_kit` - The name "get_full_kit" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Load a themed kit and every member product in full. PREMIUM (paid plan). Typical input {"slug": "founder-kit"} returns {"slug": ..., "name": ..., "products": [{"slug": ..., "name": ..., "persona": ..., "skills": [...]}, ...]}. Returns every member product of one bundle in full, so the payload is large. Use only after list_kits has confirmed the kit slug. Not for a single product (get_full_product). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": ""} (for example {"error": "unknown kit ''"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry. ``` ### `get_full_persona` - The name "get_full_persona" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Load a product's complete persona definition. PREMIUM (paid plan). Typical input {"slug": "inbox-zero-assistant"} returns {"slug": ..., "persona": ""}. Returns the persona text alone, with no skill bodies. Use when the caller needs the product's voice and operating rules only. Not when skills are also wanted - get_full_product returns persona and every skill in one call. Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": ""} (for example {"error": "unknown slug ''"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry. ``` ### `get_full_product` - The name "get_full_product" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Load one product in full: persona plus every skill's instructions. PREMIUM (paid plan). Typical input {"slug": "inbox-zero-assistant"} returns {"slug": ..., "name": ..., "persona": ..., "skills": [{"name": ..., "instructions": ...}], "free_skill": {...}}. Returns persona plus every skill for one product. Use when the caller wants the whole product. Not for a single skill (get_full_skill) and not for a bundle of products (get_full_kit). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": ""} (for example {"error": "unknown slug ''"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry. ``` ### `get_full_skill` - The name "get_full_skill" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Load one paid skill's complete instructions from a product. PREMIUM (paid plan). Typical input {"slug": "inbox-zero-assistant", "skill_name": "Deep Triage"} returns {"slug": ..., "skill": ..., "instructions": ""}. Returns one named skill, selected by skill_name. Use after preview_product has shown the skill list and the caller wants one specific paid skill. Not for the free gateway skill, which get_free_skill returns with no plan, and not for every skill at once (get_full_product). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": ""} (for example {"error": "unknown slug ''"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry. ``` ### `list_kits` - The name "list_kits" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text List the 12 themed kits with pricing and member products. FREE. Takes no arguments. Returns a list of kit objects, each {"slug": ..., "name": ..., "price_usd": N, "tagline": ..., "members": ["product-slug", ...], "availability": ...}. Use a kit's slug with get_full_kit (premium). Kits are not sold standalone on any marketplace: price_usd is the bundle's reference value, and All-Access is how a caller actually unlocks one. Use when the caller asks about bundles or bundle pricing. Not for individual products (search_catalog) and not for a kit's full contents (get_full_kit). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": ""}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry. ``` ### `preview_product` - The name "preview_product" says "preview": a word for reading. Description, as the server wrote it: ```untrusted-server-text Preview one product: metadata, persona teaser, and paid-skill teasers. FREE. Typical input {"slug": "inbox-zero-assistant"} returns {"slug": ..., "name": ..., "tagline": ..., "persona_preview": ..., "skills": [{"name": ..., "preview": ...}], "free_skill": ..., "note": ...}. Returns teasers only, never full text. Use to judge a product before committing. Not for the complete persona or skill bodies (get_full_persona, get_full_product), and not when the caller wants instructions they can act on now (get_free_skill). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": ""} (for example {"error": "unknown slug ''"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry. ``` ### `search_catalog` - The name "search_catalog" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Search all 138 catalog products by keyword and/or focus area. FREE. Typical input {"query": "email inbox", "limit": 5} returns a ranked list of product objects [{"slug": ..., "name": ..., "area": ..., "segment": ..., "tagline": ...}]. An empty query with an area set browses that area. Use when the caller names a keyword, product, or focus area to look up. Not for bundles (list_kits) and not for plain-language problem statements, which recommend_products ranks by fit rather than keyword match. Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": ""}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry. ``` ### `upgrade_info` - The description's first verb is "explain": a word for reading. Description, as the server wrote it: ```untrusted-server-text Explain how to unlock full personas, paid skills, and kits. FREE. Takes no arguments. Returns {"message": ..., "how": ..., "free_tier": ...} describing the upgrade path and what stays free. Use when a premium tool has been refused or the caller asks what a plan covers. Not for per-bundle or per-product pricing (list_kits, preview_product). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": ""}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `catalog`: ```json { "permissions": { "allow": [ "mcp__catalog__search_catalog", "mcp__catalog__preview_product", "mcp__catalog__get_free_skill", "mcp__catalog__list_kits", "mcp__catalog__upgrade_info", "mcp__catalog__get_full_persona", "mcp__catalog__get_full_skill", "mcp__catalog__get_full_product", "mcp__catalog__get_full_kit" ], "ask": [ "mcp__catalog__recommend_products" ], "deny": [] } } ```
