# Viator — AI Connector Viator publishes 2 MCP tools to Claude and is listed in the ChatGPT apps directory. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/productivity/viator/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Productivity](https://node8.ai/ai-connectors/productivity/) # Viator Search tours and attractions from Viator's catalogue Listed in ChatGPT and Claude · 2 published tools · Verified partner [ChatGPT listing](https://chatgpt.com/plugins/viator?open_in_app) [Claude connector docs](https://docs.viator.com/partner-api/mcp/) [viator.com](https://www.viator.com) Overview ## What Viator does Viator, part of TripAdvisor, opens its catalogue of tours, attractions, and organised experiences to conversational search. A broad opening question such as what there is to do in a given city can be narrowed step by step. The filters named are destination, dates, price range, and category. Results lead with practical information so that two options can be weighed without opening a separate page for each. The example prompts move from a general question about the Vatican tomorrow to a request for more detail on one guided tour of the Colosseum, which is the pattern the app is built around: broad first, then specific. ### Who it is for Travellers filling days at a destination who want bookable activities rather than general sightseeing advice. ### What stands out It is built for progressive narrowing, moving from a city-level question to a single named tour without leaving the conversation. Availability ## Where Viator is listed Viator ships this on both marketplaces: Viator is listed in the Claude connectors directory and in the ChatGPT apps directory, under the same publisher domain. Only 392 of the 3,150 products in this directory are listed in both marketplaces. One MCP server can serve both surfaces; what differs is each platform's listing and review process. ChatGPT listing ## In the ChatGPT apps directory Developer TripAdvisor Inc. Filed under Travel Listed since June 2026 Authentication Authenticates when installed Website [viator.com](https://www.viator.com) Policies published Privacy policy · Terms of service Official listing [Open in ChatGPT](https://chatgpt.com/plugins/viator?open_in_app) Snapshot August 2026 ### Example prompts from the listing - What can I do in the Vatican tomorrow? - Show me more details on the Colosseum guided tour Claude listing ## In the Claude connectors directory Viator publishes 2 tools to Claude, a deliberately narrow surface; only 5.3% of the 1,253 Claude-listed connectors expose fewer. The median Claude-listed connector filed under Productivity publishes 12, so this one sits 10 tools below its bucket's median, 408th of 462. It falls in the 1-3 tools band, which holds 16.4% of the Claude directory. ### Measured against the live endpoint A direct call to the endpoint returned 2 tools, matching the 2 the listing publishes. Probed 2026-08-07. #### Tools the server actually returns - `get_experience_details` - `search_experiences` Viator publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally. Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there. Publisher Viator Verification Verified partner (37.8% of the Claude directory) Filed under Productivity Endpoint `https://exp-app-mcp.prod.ep.viator.com/mcp` Documentation [Publisher setup docs](https://docs.viator.com/partner-api/mcp/) Published tools 2 · 1-3 tools band Depth rank in Productivity 408 of 462 Snapshot August 2026 Viator carries partner verification in the Claude directory, which 474 of 1,253 listings do (37.8%). That is a review step past self-publishing, not an Anthropic-built server.
