GuruWalk Free Tours

Use the GuruWalk MCP server to search free tours:

https://guruwalk-api-44909317956.europe-southwest1.run.app/mcp

The server currently exposes one tool:

• search

Tool Contract

search input:

• city (string): lowercase slug in English with spaces replaced by -
• start_date (string): yyyy-mm-dd
• end_date (string): yyyy-mm-dd
• language (string): two-letter code, usually es, en, de, it

search output:

• Tool returns content[0].text containing a JSON string.
• Parse that string to get an array of tours.
• Each tour contains:
• title, url, meetpoint_address, average_rating, duration, guru.name, image_url
• events[] with start_time (UTC), available_spots, language

Execution Workflow

1. Determine city, date range, and preferred language from user request.
2. Normalize city to slug format:
• new york -> new-york
• san sebastian -> san-sebastian
3. Use valid ISO dates for both fields.
4. Call search.
5. Parse JSON from content[0].text.
6. Filter and rank results for user-facing output:
• keep only events with available_spots > 0
• prioritize events matching requested language when possible
• prefer higher average_rating, then earlier upcoming time
7. Return concise options with booking URL and next available slots.

Defaults

• If user does not specify language, use:
• es for Spanish conversation
• en otherwise
• If user does not specify dates, ask for dates before calling the tool.
• If date intent is relative, convert to explicit dates before calling.

Response Format to User

For each recommended tour include:

• Tour title
• Rating
• Duration
• Guide name
• Meeting point
• 1-3 next available sessions (with timezone label)
• Booking URL

If no tours are found:

• explain that no availability was returned for the given city/date range
• propose adjusting one variable at a time: city slug, dates, or language

Observed Edge Cases (from live MCP inspection)

• search is the only available tool; no MCP resources/prompts/templates are exposed.
• city with spaces (e.g. New York) can return empty results.
• start_date > end_date can return empty results instead of validation error.
• Non-ISO dates can still be accepted by backend, but always send ISO yyyy-mm-dd.
• Some locale/language combinations can return tours with title: null; handle gracefully.

Validation Notes

• Keep executable validation commands outside this skill file.
• Validate behavior by confirming:
• the MCP server exposes the search tool
• search results arrive as a JSON string in content[0].text
