viator-mcp

MCP server for the Viator Partner API (v2) — search tours, activities and experiences for Claude. Search the catalog with structured filters or free text, get product details and availability schedules, browse attractions and destinations, all over stdio.

Developed and maintained by AI (Claude Code). Use at your own discretion.

Quick start

{
  "mcpServers": {
    "viator": {
      "command": "npx",
      "args": ["-y", "@chrischall/viator-mcp"],
      "env": { "VIATOR_API_KEY": "your-viator-partner-api-key" }
    }
  }
}

Get a key by signing up as a Viator affiliate at partnerresources.viator.com — the Basic Access tier is free. This server targets that tier: read-only search/content/availability; no booking endpoints (product results carry a productUrl for booking on viator.com, tagged with your affiliate id).

Tools

AreaTools
Productsvt_search_products, vt_get_product, vt_list_product_tags
Searchvt_search_freetext
Attractionsvt_search_attractions, vt_get_attraction
Availabilityvt_get_availability_schedule
Referencevt_list_destinations, vt_get_locations, vt_get_exchange_rates
Healthvt_healthcheck — is this connector working? Reports whether VIATOR_API_KEY resolved, whether Viator accepted it, and what to fix. Start here when another tool fails: an empty result can mean "no products" or "never authenticated".

All tools are read-only. vt_search_products and vt_search_freetext accept compact: true for slim summaries (code, title, price, rating, booking URL) instead of full records.

Environment

VariableRequiredDescription
VIATOR_API_KEYyesViator Partner API key (sent as exp-api-key)
VIATOR_API_BASE_URLnoAPI host (default production; set https://api.sandbox.viator.com/partner for a sandbox key)
VIATOR_LANGUAGEnoAccept-Language for response text (default en-US)
VIATOR_CACHE_TTLnoSeconds to cache identical reads (default 60; 0 disables)
VIATOR_STATIC_CACHE_TTLnoSeconds to cache reference data — destinations, tags, locations, exchange rates (default 3600)

Viator rate-limits per endpoint on a rolling 10-second window and answers 429/503 with Retry-After; the client honors it (one retry) and the response cache absorbs repeated identical calls.

Development

npm install
npm test          # vitest; no real network calls
npm run build     # tsc + esbuild bundle

The API surface this server is coded against is pinned in docs/VIATOR-API.md.
