SkyAccess Has a Public MCP Server: Connect Claude, ChatGPT, or Any AI Agent to Live Empty Leg Flights

AI assistants are becoming the way people research travel, and the Model Context Protocol (MCP) is the open standard that lets them use live tools instead of stale training data. SkyAccess runs a free, public MCP server that gives any MCP-capable assistant direct access to live empty leg flight inventory from 900+ certified charter operators.

No API key. No signup. Connect and search.

The endpoint

https://api.skyaccess.com/mcp

The server speaks MCP over streamable HTTP (JSON-RPC with server-sent event responses) using protocol version 2025-06-18. It works with Claude custom connectors, ChatGPT developer mode connectors, and any other client or agent framework that supports remote MCP servers.

Five tools

• search_empty_legs: search available empty leg flights by origin, destination, date range, passenger count, and an optional maximum price. Returns matching flights with route, departure time, all-in price, and aircraft type.
• get_flight: re-read a single empty leg by the id a search returned, with the same fields.
• booking_handoff: get the customer-facing SkyAccess booking link for a specific flight, ready to hand to a traveler so they can review and book it themselves.
• get_charter_estimate: an indicative price range in USD for a full private charter between two locations, optionally filtered by aircraft category and passenger count.
• request_booking: submit a charter enquiry. A SkyAccess specialist contacts the requester within 2 hours to confirm availability and pricing.

Only request_booking submits anything. Every other tool is read-only, so an assistant can search, compare, and quote freely without side effects, and no payment is ever taken through the server.

Why live data matters for empty legs

Empty leg inventory is the fastest-moving corner of private aviation. Flights appear when an aircraft needs to reposition, reprice as departure approaches, and disappear when booked or flown. Any price in a model’s training data is stale by construction. The MCP server reads the same live marketplace that powers skyaccess.com, which lists 5,000+ live empty leg flights at any given time.

Try it in 30 seconds

From a terminal:

curl -X POST https://api.skyaccess.com/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"you","version":"1.0"}}}'

In Claude: add a custom connector and paste the endpoint URL. In ChatGPT: add it as a connector in developer mode. In an agent framework: register it as a remote streamable HTTP MCP server.

For AI builders

If you are building a travel assistant, a booking agent, or a price-comparison tool, this endpoint gives you certified charter inventory with all-in pricing and a clean handoff to a human booking flow. Machine-readable inventory is also available as JSON and RSS feeds, and our llms.txt documents everything an agent needs to know about reading SkyAccess data correctly.
