Manage OpenTable reservations via MCP — search restaurants, check slot availability, book tables, list/cancel reservations, and manage favorites. Triggers on phrases like "book a table on OpenTable", "find me a reservation at", "what OpenTable reservations do I have", "cancel my OpenTable", "add to my OpenTable favorites", "what's available for dinner tonight at", or any request involving OpenTable restaurant reservations. Requires opentable-mcp installed and the fetchproxy browser extension running in a signed-in opentable.com tab.

opentable-mcp

MCP server for OpenTable — natural-language restaurant reservation management. Every request is relayed through the user's signed-in browser tab via the fetchproxy extension, so there's no cookie paste, no bot-wall dance, and no password handling.

• npm: npmjs.com/package/opentable-mcp
• Source: github.com/chrischall/opentable-mcp

OpenTable does not publish an official API. This server calls the same endpoints the opentable.com web app uses. Auth lives in the user's browser (OpenTable's passwordless email-OTP session). Use at your own discretion.

Setup

The MCP server is half of the picture — the other half is the fetchproxy browser extension that actually talks to OpenTable from your signed-in tab. Both are required.

1. Install the MCP server

Option A — npx (recommended)

Add to .mcp.json in your project or ~/.claude/mcp.json:

json

{
  "mcpServers": {
    "opentable": {
      "command": "npx",
      "args": ["-y", "opentable-mcp"]
    }
  }
}

Option B — from source

bash

git clone https://github.com/chrischall/opentable-mcp
cd opentable-mcp
npm install && npm run build

Then add to .mcp.json:

json

{
  "mcpServers": {
    "opentable": {
      "command": "node",
      "args": ["/path/to/opentable-mcp/dist/bundle.js"]
    }
  }
}

2. Install the fetchproxy extension

opentable-mcp shares a single browser extension with every other fetchproxy-based MCP. Install it once from github.com/chrischall/fetchproxy:

1. Install the fetchproxy extension (Chrome Web Store / Safari .dmg).
2. Sign in to https://www.opentable.com/ in the same browser profile.

The extension's toolbar badge turns green when the WebSocket + tab + auth are all good.

Full extension walkthrough: see fetchproxy.

Authentication

No env vars. Auth is whatever cookies your signed-in opentable.com tab has. If Akamai rotates _abck or OpenTable's SSO expires, visit opentable.com and click through whatever prompt appears — subsequent MCP calls will use the fresh cookies automatically.

The server throws SessionNotAuthenticatedError (with a clear message) if it detects the sign-in interstitial.

Tools

Discovery

Tool	Description
opentable_search_restaurants(term?, location?, date?, time?, party_size?, latitude?, longitude?, metro_id?)	Search by free-text + optional location / date / party size. Returns cuisine, neighborhood, price band, rating, URL slug. No bookable slots — call find_slots for those.
opentable_get_restaurant(restaurant_id)	Full detail for one restaurant by URL slug (e.g. "state-of-confusion-charlotte"). Includes diningAreas[] — you need one of their ids to book. Numeric ids 404 here; always pass the slug.
opentable_find_slots(restaurant_id, date, time, party_size)	List bookable slots for a restaurant on a date + party size. Each slot has a short-lived reservation_token + slot_hash (book within a minute or two of fetching).

User

Tool	Description
opentable_list_reservations(scope?)	List reservations. scope: upcoming (default), past, all. Each entry has the confirmation_number + security_token needed to cancel.
opentable_get_profile	Authenticated user's profile: name, email, phones, loyalty points, home metro, member-since. No payment data.

Bookings

Tool	Description
opentable_book_preview(restaurant_id, date, time, party_size, reservation_token, slot_hash, dining_area_id)	Preview a booking: runs slot-lock + fetches /booking/details, returns the cancellation policy, the saved card that would be held/charged, and a short-lived booking_token. REQUIRED before opentable_book for CC-required slots; safe to call for others. Holds the slot for ~60-90s.
opentable_book(restaurant_id, date, time, party_size, reservation_token, slot_hash, dining_area_id, booking_token?)	Book a slot. For CC-required slots, pass the booking_token from opentable_book_preview — the tool errors out pointing you at preview if you don't. For non-guaranteed slots, booking_token is optional (but harmless). Returns confirmation_number + security_token (save both — they're required for cancel).
opentable_cancel(restaurant_id, confirmation_number, security_token)	Cancel by the triple returned from book or list_reservations.

Favorites

Tool	Description
opentable_list_favorites	List saved restaurants.
opentable_add_favorite(restaurant_id)	Add a restaurant (numeric id) to Saved Restaurants.
opentable_remove_favorite(restaurant_id)	Remove from Saved Restaurants.

Non-instant bookings

OpenTable restaurants fall into three categories. Check opentable_get_restaurant.bookable and the per-slot booking_type before invoking opentable_book.

bookable	booking_type	What it means	Action
true	instant	Standard restaurant, one-click book.	Today's path: optional preview, then opentable_book.
true	experience_mandatory	Restaurant requires picking an Experience (prix-fixe, tasting menu, etc.) before booking. Slot carries one or more experience_ids.	Call opentable_get_restaurant to see the per-area bookableExperiences. Call opentable_book_preview with both dining_area_id AND experience_id. Then opentable_book with the returned booking_token.
false	n/a	Listing-only: OpenTable shows the page but reservations go through the restaurant directly.	Surface the restaurant's phone and url to the user; do NOT call opentable_book.
true	request	(Reserved) Request-to-book. Not surfaced in v1.	n/a

When booking_type === "experience_mandatory", do not treat the return as a confirmed reservation — it's still instant-confirm, but the booking_token's experience block tells the agent which Experience the user committed to (community-table dining, chef's counter, etc.). Mention the Experience name in the user-facing confirmation.

Modifying a reservation

To change date/time/party_size/dining_area/experience on an existing reservation, use opentable_modify_preview + opentable_modify. Mirrors book's preview→commit pattern.

1. Call opentable_find_slots for the NEW time you want.
2. Call opentable_modify_preview with:
   • The existing reservation's restaurant_id, confirmation_number, security_token (from opentable_list_reservations or the original opentable_book result).
   • The NEW slot's date, time, party_size, reservation_token, slot_hash, dining_area_id, and (for Experience-mandatory restaurants) experience_id.
3. Surface the returned cancellation_policy and any CC re-hold details to the user.
4. Call opentable_modify with the modify_token from preview + the same identifying args. Returns was_modified: true and the preserved confirmation_number.

Don't use cancel + book to "modify" — same-day cancel-then-rebook trips OpenTable's double-booking check and risks losing the slot to another diner.

Workflows

Book a specific restaurant for a specific evening (no-CC slot):

text

opentable_search_restaurants(term: "state of confusion", location: "Charlotte")
  → note the restaurant_id (numeric) + URL slug
opentable_get_restaurant(restaurant_id: "state-of-confusion-charlotte")
  → pick dining_area_id from diningAreas[]
opentable_find_slots(restaurant_id, date: "2026-05-01", time: "19:00", party_size: 2)
  → pick a slot, grab reservation_token + slot_hash
opentable_book(restaurant_id, date, time, party_size, reservation_token, slot_hash, dining_area_id)
  → save confirmation_number + security_token

Book a CC-required slot (prime-time at a busy restaurant):

text

opentable_find_slots(...)                                   # pick one
opentable_book_preview(restaurant_id, date, time, party_size, reservation_token, slot_hash, dining_area_id)
  → shows cancellation_policy (e.g. "$50/guest no-show fee, cancel 24h ahead for no charge")
  → shows payment_method (e.g. Mastercard •••• 4242)
  → returns booking_token

   [Surface the policy + card to the user. Let them confirm in plain English.]

opentable_book(..., booking_token: <from preview>)          # commits
  → save confirmation_number + security_token

If opentable_book is called on a CC-required slot without booking_token, it
errors out with "call opentable_book_preview first". That's the gate.

"What's available tonight for 2 at a nice Italian spot?":

text

opentable_search_restaurants(term: "italian", date: "2026-04-20", time: "19:00", party_size: 2, latitude: <lat>, longitude: <lng>)
  → scan results, pick candidates
opentable_find_slots(restaurant_id, date, time, party_size)  # for each candidate

Cancel an upcoming reservation:

text

opentable_list_reservations(scope: "upcoming")
  → find the one to cancel, read confirmation_number + security_token
opentable_cancel(restaurant_id, confirmation_number, security_token)

Save a restaurant for later:

text

opentable_search_restaurants(term: "carbone")
  → pick the restaurant_id
opentable_add_favorite(restaurant_id)

Notes

• CC-required bookings must go through preview first. Restaurants that hold your card for a no-show fee (common at prime-time tables) require opentable_book_preview before opentable_book. The preview surfaces the cancellation policy and the saved card last-4; the booking_token it returns is opaque, stateless, and expires with OpenTable's ~60–90 s slot lock. If the user has no default payment method on opentable.com, preview throws a link to the account settings page. Plain opentable_book (no token) refuses CC-required slots with a pointer to preview.
• Slot tokens are short-lived. reservation_token + slot_hash from find_slots typically expire within a minute or two. Call find_slots just before book, and if the user is deliberating, re-fetch.
• dining_area_id is mandatory for book. OpenTable's /r/<numeric-id> routes 404 — there's no way to auto-resolve the default dining room. Always call opentable_get_restaurant(slug) first and pick a room from diningAreas[].
• /user/favorites has a read-after-write lag. A fresh add_favorite may not show up in list_favorites for ~10 s. The 204 response from add/remove is authoritative.
• Extension must be running. If the MCP server throws "fetchproxy extension offline — install it and open an opentable.com tab", the user needs to: install the fetchproxy extension (https://github.com/chrischall/fetchproxy), open an opentable.com tab, and sign in. The popup has a green/yellow/red status indicator.
• Service worker sleep. Chrome MV3 SWs sleep after ~30 s idle. Cold wake adds ~2-5 s to the first request. Subsequent calls are fast.
• Persisted-query hashes. find_slots, book, cancel, and search use Apollo persisted queries pinned by sha256Hash. If OpenTable redeploys and returns PersistedQueryNotFound, re-capture by reading window.__APOLLO_CLIENT__.queryManager.mutationStore['1'].mutation.documentId from DevTools on the relevant opentable.com page (see CLAUDE.md → "Conventions").
