What the publisher says

From the Viator repository's README, as published. We do not edit it. Read it on GitHub

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

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

Environment

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.
