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
| Area | Tools |
|---|---|
| Products | vt_search_products, vt_get_product, vt_list_product_tags |
| Search | vt_search_freetext |
| Attractions | vt_search_attractions, vt_get_attraction |
| Availability | vt_get_availability_schedule |
| Reference | vt_list_destinations, vt_get_locations, vt_get_exchange_rates |
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
| Variable | Required | Description |
|---|---|---|
VIATOR_API_KEY | yes | Viator Partner API key (sent as exp-api-key) |
VIATOR_API_BASE_URL | no | API host (default production; set https://api.sandbox.viator.com/partner for a sandbox key) |
VIATOR_LANGUAGE | no | Accept-Language for response text (default en-US) |
VIATOR_CACHE_TTL | no | Seconds to cache identical reads (default 60; 0 disables) |
VIATOR_STATIC_CACHE_TTL | no | Seconds 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 test # vitest; no real network calls
