LetsFG: search and book real flights and hotels from chat through the hosted LetsFG service. A Nodecode rewrite of LetsFG/LetsFG by LetsFG.

LetsFG searches every airline and the major travel sites in one go, prices the bags, checks every airport in a city and tests split tickets, then books the flight or the room on your own LetsFG account. This cell is the plugin rewritten natively: the same hosted server, called over HTTP by the cell itself, the same tools as tools the model can call, and the plugin's travel-booking skill as this cell's manual topic.

Get it

Tell the agent "add the letsfg cell", or run nodecode add nc://letsfg.

Set it up

LetsFG signs in with OAuth, so the cell needs a bearer token from a LetsFG sign-in: either an environment variable that holds one, or a file that holds one.

"letsfg": {
  "enabled": true,
  "server": "https://letsfg.co/mcp",   // the default; the hosted endpoint
  "token_file": "~/.secrets/letsfg",   // or "token_env": "LETSFG_TOKEN"
  "timeout_seconds": 60                // a hotel search can take half a minute
}

Then (restart-cells "nodecode-letsfg"). No card is needed to sign in; when a booking needs one, its result gives a link to add it on letsfg.co.

Use it

Ask for a trip:

• "The cheapest flight from Warsaw to London next Friday, back Sunday."
• "A hotel in Paris for 12-14 November, two adults, breakfast, under 400 EUR."
• "Where in Southern Europe can I fly from Berlin for four nights in October?"
• "Book option A for me."

The model gets five tools: letsfg_search_flights, letsfg_search_hotels, letsfg_results, letsfg_book (the write path: book, cancel, stop, answer a booking question) and letsfg_call (every other LetsFG tool by name). From eval: (letsfg:tools) lists what the account can do, (letsfg:call-tool "find_airports" :query "Warsaw") calls one, and /letsfg status says whether the token was read.

Booking is real. A search changes nothing; a booking holds money on your saved card, and it starts only when you press Approve in the LetsFG e-mail — nothing in the chat can start or approve one. Card details never enter the chat, and the cell books only what you picked.

Left out

The plugin's Hermes-specific pieces: the manifest, the MCP connector declaration (this cell is the client) and the three tools that exist only for LetsFG's in-app cards in other clients.
