GuruWalk MCP — Affiliate Integration Guide
GuruWalk exposes a subset of its tour catalog through the Model Context Protocol (MCP), allowing affiliates to embed tour discovery, browsing, and availability checking directly into their own AI agents and assistants.
All URLs returned by the tools include your affiliate ?ref=<username> parameter automatically, so bookings driven by your agent are attributed to your account.
Endpoint
POST https://back.guruwalk.com/mcp/affiliates
The server implements MCP over Streamable HTTP, stateless mode. Every request is independent — no session state is maintained between calls.
Authentication
Include your API key on every request using one of these headers:
Authorization: Bearer <api_key>
or
Api-Key: <api_key>
Requests without a valid key receive 401 Unauthorized.
Protocol
This server follows the MCP specification. Use any MCP-compatible client library:
- Python:
mcp - TypeScript/JavaScript:
@modelcontextprotocol/sdk
The transport is Streamable HTTP (not SSE, not stdio). The server is stateless — pass stateless: true (or equivalent) in your client transport configuration.

Typical Flow
A natural conversation flow for a travel assistant looks like this:
1. discover_destination(destination: "Barcelona", language: "en")
→ get place info, category list, and featured tours
2. browse_category(category_id: <id from step 1>, language: "en")
→ drill into a specific category to see all tours
3. check_availability(tour_id: <id from step 1 or 2>, from_date: "...", to_date: "...")
→ show the user available dates and times with direct booking links
You can also skip step 2 and go directly from discover_destination to check_availability if the user already selected a tour from the featured list.
Attribution
All url and booking_url fields in every tool response automatically include ?ref=<your_username> so bookings originating from your agent are tracked and credited to your account. Do not strip or modify these parameters.
