easygroupflights

easygroupflights MCP

A Model Context Protocol server for easygroupflights.com — IATA-accredited group air travel, with negotiated fares from 500+ airlines.

It lets an AI assistant do what the website does: work out whether a trip is a group booking, gather what an agent needs to price it, and put the enquiry in front of a human — or, for a party too small to be a group, find ordinary bookable fares.

Why a group needs a different tool

A group fare is negotiated directly with the airline. It is not sold through any public booking engine, so no search API can return a price for one. What this server does instead is submit a complete, structured enquiry and tell the traveller honestly what happens next: a specialist replies by email in about two hours, up to 24 for complex routings.

The dividing line is 10 seated travellers. Lap infants under two don't occupy a seat and don't count.

Tools

The two fare tools are withheld from tools/list unless PELIKAN_MCP_URL is set — an advertised tool that cannot run is worse than one that isn't there.

egf_get_service_info ends with each market's human contacts — website, email, phone and WhatsApp — so an agent can hand a user to a person.

Every tool:

• sets all four annotations (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) explicitly. Only egf_request_group_quote is a write, and nothing is destructive.
• declares an outputSchema and returns structuredContent alongside the text.
• takes snake_case inputs.

The write comes as a pair, because not every client asks the user before a write. The prepare tool returns the summary and a confirmation_token, which is signed with CONFIRM_SECRET and valid for 15 minutes. The write takes only that token, so it cannot send anything the summary did not show.

It accepts an optional idempotency_key. Without one, the token itself is the key, so a prepared write is carried out at most once. Keys are kept for 24 hours, per Cloudflare data centre.

Callers presenting GATEWAY_TOKEN as a bearer token are the Tripdesk gateway:

• They get their own rate limit of 1,200 a minute; everyone else gets 60 a minute per address.
• Their booking links are left untagged. Direct callers' links get utm_source=mcp.

Every tool call answers within 28 seconds.

egf_search_flights pages with limit (default 10, at most 20) and cursor. Each fare carries one opaque offer_id, valid for 30 minutes. It is all egf_get_offer needs. Search results carry no booking links, and no session or trip ids.

Removed in 2.1

egf_prepare_flight_offer and egf_send_flight_offer (1.x send_flight_offer) are gone. They passed through the fare service's agent-facing offer email, which sent a branded email, with the caller's own text, to any address. The directory review flagged that; egf_get_offer returns the booking link instead.

Upgrading from 1.x

2.0 renamed the tools with the egf_ prefix and the inputs to snake_case. Most of what worked in 1.x still does:

• The old names (request_group_quote, …) are still answered, though no longer listed.
• camelCase arguments (departureDate, fareId, …) are read as their snake_case names.
• A 1.x one-step write is refused, with a message naming the prepare tool to call first.

Privacy

What the server receives, where it goes and how long it is kept: easygroupflights.com/mcp-privacy/. The controller is pelicantravel.com s.r.o.; privacy questions go to [email protected].

Prompts

Guided briefs. In Claude Desktop and claude.ai they are under + → Connectors → Add from Easygroupflights; in Claude Code they are /mcp__easygroupflights__<name>. Each one walks the user through what the desk needs, plus the questions only that kind of trip raises, and submits only once the user confirms.

Every prompt takes an optional market (en, pl, at) plus whatever is already known: origin, destination, dates, travellers.

Resources

Material an agent can quote rather than recall, each served as markdown under its public URL — so a cited resource is already a link a reader can follow.

• Guides: every content page of the three market sites (16 each, in English, Polish and German), read from the /mcp-resources.json each site publishes.
• Studies: the published EGF Data Desk studies, in English and Polish, read from each blog's Ghost Content API. Tables stay tables.

Both are fetched on demand and cached for an hour, so new content reaches agents without redeploying the server.

Use it

claude mcp add --transport http easygroupflights https://mcp.easygroupflights.com/mcp

In Claude Desktop or claude.ai: Settings → Connectors → Add custom connector, and paste https://mcp.easygroupflights.com/mcp.

Or in any other MCP client's config:

{  "mcpServers": {    "easygroupflights": {      "type": "http",      "url": "https://mcp.easygroupflights.com/mcp"    }  }}

Transport is streamable HTTP. The server is stateless — it issues no session id and needs no Durable Objects, because every tool call is self-contained.

Configuration

Public values live in wrangler.toml:

Three secrets, set with wrangler secret put:

Licence

MIT. See LICENSE.

Enquiries are attributed to the bare market domain. Autopilot only processes a source it recognises, so nothing may be appended to it.

Develop

npm installnpm run dev        # wrangler dev on :8787npm test           # unit tests, no networknpm run typechecknpm run deploy     # wrangler deploy

Put local secrets in .dev.vars (gitignored). Leaving AUTOPILOT_API_KEY unset is the safe way to exercise egf_request_group_quote end to end: it validates everything and stops at the intake boundary without creating a real lead.

Drive it by hand with:

curl -s localhost:8787/mcp -H 'Content-Type: application/json' \  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

GET / serves a human-readable page, /health a status probe, and /.well-known/mcp.json a manifest for directories.

Markets

One site per market; the market decides both which brand handles the enquiry and which domain the lead is attributed to.
