Claude Code: deny. ### `set_run_sheet` - The name "set_run_sheet" says "set": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text [Sign-in required] Writes a reviewed timeline to the wedding as the day-of run sheet, replacing the one there — costs no credits and returns the number of events saved and the number replaced. Times are 24h HH:MM in chronological order; an out-of-order sheet is refused before anything is written. ``` ## Changes things (7) Creates or changes something that can be changed back. Claude Code: ask. ### `add_guests` - The name "add_guests" says "add": a word for a change. Description, as the server wrote it: ```untrusted-server-text [Sign-in required] Appends up to 100 named guests to the guest list in one write — costs no credits and returns the names added, the names skipped as duplicates and the new total. Existing guests are left untouched, the whole batch is validated before anything is written, and a member whose role only proposes guests gets proposals recorded for the couple instead of additions. ``` ### `quote_cost` - 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 [Free] Quotes a tool before it is called — costs no credits and returns the credits a successful call spends (0 for every tool today), the scopes it needs, the rate limits it runs under, its annotations and whether it accepts an idempotency_key. Nothing is charged on failure for any tool, so there is nothing to refund. ``` ### `set_checklist_item` - The name "set_checklist_item" says "set": a word for a change. Description, as the server wrote it: ```untrusted-server-text [Sign-in required] Marks one checklist item done or not done — costs no credits and returns the item with its previous and new state. The item is addressed by the `id` get_checklist returns (stable even when the list changes) or by its `index` for items without an id; an item that does not exist is refused rather than created. ``` ### `suggest_day_schedule` - The name "suggest_day_schedule" says "schedule": 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 [Sign-in required] Generates a 10–15 event wedding-day timeline in 24h time, shaped by the connected account’s venue, ceremony type and guest count — costs no credits (rate-limited to 10 generations a minute) and returns the schedule for review; set_run_sheet is the separate call that writes one to the wedding. ``` ### `suggest_menu` - 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 [Sign-in required] Generates a wedding menu — cocktail, starters, mains, desserts, drinks, cake and a children’s menu — sized to the connected account’s guest count, theme and budget — costs no credits (rate-limited to 10 generations a minute) and returns the menu for review; nothing is written to the wedding. ``` ### `update_provider_profile` - The name "update_provider_profile" says "update": a word for a change. Description, as the server wrote it: ```untrusted-server-text [Partner] Updates the connected provider’s listing — description, services, price range, website, Instagram, phone — as a merge patch — costs no credits and returns the fields changed. Omitted fields are left alone; plan, verification, featuring and status are refused by name because they are sold or earned, never self-assigned. ``` ### `update_wedding` - The name "update_wedding" says "update": a word for a change. Description, as the server wrote it: ```untrusted-server-text [Sign-in required] Updates the wedding’s details — date, venue, budget, guest count, theme, notes — as a merge patch — costs no credits and returns the fields changed and whether the wedding was created by this call. Omitted fields are left alone; a value that contradicts what the couple said in nyna’s chat comes back as `conflict` and is written only when sent again within 15 minutes; share-control fields are refused by name, never silently dropped. ``` ## Only reads (15) Looks things up and changes nothing. Claude Code: allow. ### `get_checklist` - The name "get_checklist" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text [Sign-in required] Reads the couple’s checklist — costs no credits and returns each item with its id, title, status, due date and category, plus the totals (all, done, to do) so nothing has to be counted. ``` ### `get_credit_balance` - The name "get_credit_balance" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text [Sign-in required] Reads the connected account’s credit balance — costs no credits and returns the balance, the price of each metered action in the nyna app, and the list of MCP tools that spend credits (none today). ``` ### `get_day_of_timeline` - The name "get_day_of_timeline" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text [Sign-in required] Reads the wedding-day plan — costs no credits and returns the run sheet, vendor coordination status, guest figures, readiness score and flags, and the days remaining; what has not been filled in is named rather than guessed at. ``` ### `get_guests` - The name "get_guests" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text [Sign-in required] Reads the guest list — costs no credits and returns each guest with RSVP status, side and table, plus head-count totals by status so nothing has to be tallied. ``` ### `get_provider` - The name "get_provider" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text [Free] Reads the indexed record of a single provider by the id search_providers returns — costs no credits and returns the name, address and nyna page (live Google rating, reviews, phone and website are on that page, not stored here under Google Places terms). ``` ### `get_provider_inquiries` - The name "get_provider_inquiries" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text [Partner] Reads the enquiries couples sent through the connected provider’s nyna listing, newest first — costs no credits and returns each enquiry (sender name, message, wedding date, status) plus totals by status so the pipeline needs no counting. ``` ### `get_provider_profile` - The name "get_provider_profile" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text [Partner] Reads the connected provider account’s own listing — costs no credits and returns an `editable` half (exactly the fields update_provider_profile accepts, under the same names: description, services, price range, website, Instagram, phone) and a `derived` half nyna decides (business name, category, city, plan, verification, featuring, status). ``` ### `get_provider_stats` - The name "get_provider_stats" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text [Partner] Reads the connected provider’s listing performance over a chosen window — costs no credits and returns views, enquiries and conversion for the window actually measured, naming any figure nyna does not collect rather than returning a null nobody can interpret. ``` ### `get_wedding` - The name "get_wedding" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text [Sign-in required] Reads the connected account’s wedding — costs no credits and returns the date, venue, budget, guest count and theme in a `writable` half (exactly the fields update_wedding accepts, under the same names) plus a `derived` half with days remaining, guest totals and checklist progress. A member’s role decides what comes back: the budget is omitted for a role without budget:view. ``` ### `list_cities` - The name "list_cities" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text [Free] Lists the cities with an indexed provider directory, optionally filtered by region — costs no credits and returns city slugs (the `city` value search_providers takes), country, region, whether nyna features the city, and its nyna page. ``` ### `list_gift_categories` - The name "list_gift_categories" says "list": a word for reading.

Description, as the server wrote it: ```untrusted-server-text [Free] Lists the kinds of wedding provider nyna indexes (venues, caterers, photographers…) — costs no credits and returns the closed set of category slugs that search_providers takes as `category`, each with its English and French name and its nyna page. Any `category` value outside this set is refused with the valid list. ``` ### `parse_guest_list` - The name "parse_guest_list" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text [Sign-in required] Parses a pasted guest list — one per line or comma-separated, with or without emails and phones — into structured guests with detected roles — costs no credits (rate-limited to 10 a minute) and returns them for review; add_guests is the separate call that saves the ones kept. ``` ### `search_gift_ideas` - The name "search_gift_ideas" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text [Free] Searches the curated wedding-gift ideas by category, country, title and price — costs no credits and returns up to 50 ideas with price, currency, image and a store link (some links carry an affiliate tag that never changes the ordering). Slugs are the ones list_gift_categories returns; any other value is refused with the valid set. ``` ### `search_providers` - The name "search_providers" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text [Free] Searches the indexed wedding providers — venues, caterers, photographers, florists and more — by category, city or name — costs no credits and returns up to 50 providers with address, Google rating, review count and nyna page, plus how old the index is. `category` and `city` are slugs from list_provider_categories and list_cities; any other value is refused with the valid set rather than quietly ignored. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `nyna`: ```json { "permissions": { "allow": [ "mcp__nyna__list_provider_categories", "mcp__nyna__list_cities", "mcp__nyna__search_providers", "mcp__nyna__get_provider", "mcp__nyna__list_gift_categories", "mcp__nyna__search_gift_ideas", "mcp__nyna__get_wedding", "mcp__nyna__get_checklist", "mcp__nyna__get_guests", "mcp__nyna__get_day_of_timeline", "mcp__nyna__get_credit_balance", "mcp__nyna__parse_guest_list", "mcp__nyna__get_provider_profile", "mcp__nyna__get_provider_inquiries", "mcp__nyna__get_provider_stats" ], "ask": [ "mcp__nyna__update_wedding", "mcp__nyna__set_checklist_item", "mcp__nyna__add_guests", "mcp__nyna__suggest_menu", "mcp__nyna__suggest_day_schedule", "mcp__nyna__update_provider_profile", "mcp__nyna__quote_cost" ], "deny": [ "mcp__nyna__set_run_sheet" ] } } ```
