Overview

AI-generated overview

A free, no-login remote MCP server that lets an assistant search and compare live flight offers between two airports, with prices and booking links.

What you can do
Search live one-way and round-trip flight offers between an origin and destination for given dates, with passenger counts, cabin class, currency and response language.
When to use it
Useful when someone wants to compare flights, airlines, prices, layovers or booking links for a trip, and does not want to sign up for an account or supply an API key.
Requirements
A remote streamable HTTP endpoint; no API key, login or local runtime is needed. Clients that only support stdio can bridge to it with a proxy such as mcp-remote. The server rate-limits requests to about one per second.
Before you install
Results and booking links are valid for only about 15 minutes, and prices come from a real-time bidding process, so they are not guaranteed. Booking links carry affiliate attribution, so the provider may earn a commission. The server does not book, change or cancel flights and does not charge users.

Installation

In SourceWeft

  1. Open OctoTrip Flights in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/app.octotrip%2Fflights/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Tool: search

Searches live flight offers between an origin and destination for given travel dates. Supports one-way and round-trip searches with flexible passenger counts and cabin class. Returns price-ranked results grouped by number of stops, showing the cheapest options from multiple airlines and booking platforms.

Result Validity

Search results and booking links are valid for approximately 15 minutes. Flight prices are determined through a real-time bidding process and are not guaranteed beyond this window. If a user wants to book, they should do so promptly. For stale results, run a new search.

Error Responses

The server returns structured errors with suggestions:

  • airport_not_found -- airport could not be resolved. Try an IATA code, city name, or airport name.
  • disambiguation_needed -- multiple airports found (e.g. "New York" returns JFK, LGA). Pick one and retry.
  • invalid_date -- date format not recognized. Use YYYY-MM-DD, DD.MM.YYYY, or similar.
  • no_results -- no flights available for the given criteria. Try different dates or a nearby airport.

Example Prompts

  • Find me the cheapest direct flight from New York to London in August
  • Compare flights from Frankfurt to Munich on July 15, round-trip returning July 22
  • I need a one-way flight from LAX to Tokyo next Friday, economy class
  • Search for 2 adults and 1 child flying from Barcelona to Paris on September 1
  • What's the cheapest business class flight from Dubai to Singapore this month?
