MCP configurations page

Here is the content formatted and structured for your Strapi CMS. It matches the clear, instructional tone and layout of the TourRadar MCP page, but is tailored specifically for the Greca MCP endpoint and specifically targets the AI Agents you requested.

You can easily copy and paste these sections into your Strapi Rich Text fields or Dynamic Zone components.

Connect to Greca's MCP server

Connect an MCP-compatible AI assistant to Greca's server so you can discover curated multi-day tours, ask detailed questions about custom Mediterranean itineraries, and plan your perfect trip to Greece in natural language.

Greca's MCP server works seamlessly with leading AI assistants. Whichever assistant you use, you just need to add the Greca MCP server URL. There is no account and no sign-in required. Pick your assistant below to get started.

Note: Greca's MCP is a remote server and needs no authentication. Use https://aiplan.greca.co/mcp for your connection. Menu names in each assistant can change over time, so if a step looks different, check your assistant's own MCP documentation.

Ask your first question

Once connected, try one of these natural language prompts:

  • "Plan a 7-day custom itinerary in Greece starting in Athens."

  • "Find me boutique accommodations in Crete for under €200 a night."
  • "Tell me more about your guided Acropolis tours. What is included and how much walking is involved?"

Things to know

Keep the following in mind after you connect your assistant to Greca:

  • Go beyond basic search: Most travel AI stops at generic suggestions. Greca's MCP lets your assistant check live availability, real pricing, and build actionable custom itineraries directly inside the conversation.
  • Pricing is dynamic: Always confirm before you book. Prices and availability for accommodations and transfers change constantly. Whatever an assistant tells you should match what you see at the final booking step.
  • Privacy first: Greca's MCP is public and read-only. There is no API key, and no personal data is attached to your connection. It exposes the same high-quality travel inventory that is publicly available on Greca's website.
