Kactus

MCP server openai

Discover and compare event venues for meetings, offsites, seminars, and corporate gatherings with Kactus. Whether you need a central meeting space with natural light, a residential venue with bedrooms, or a unique location for a team experience, Kactus helps you find the right option based on location, capacity, and event needs.

Simply describe what you’re looking for in ChatGPT. Kactus will surface relevant venues and display them in an interactive map and results widget so you can compare key criteria at a glance (capacity, amenities, photos, and location). When you find the right fit, open the venue page to review details and request a quote—no dates or availability required at this stage.

Example prompts:

  • “Find meeting venues for 30 people in Paris with natural light.”
  • “Residential offsite for 40 people with 20 bedrooms near Bordeaux.”
  • “Show me a castle venue for 60 people near Nantes.”
