LetsFG

Search and book real flights and hotels through the hosted LetsFG MCP server (Streamable HTTP, OAuth 2.1 + DCR), with the letsfg travel-booking workflow skill bundled: fares across airlines and the major travel sites, flexible dates, destinations in a region, bookable hotel rates, then book, follow and stop bookings. Portable Agent Plugins v1 package (skills/ only; the server is added by the sign-in command below).

Good to know before installing

Hosted-only connector with no local code: every tool call goes to the vendor's remote MCP server at letsfg.co/mcp. Booking tools act on real money: a booking holds the price on the card saved on the user's LetsFG account (captured only once the airline or hotel confirms, released if it fails); per LetsFG, a booking, paid extra or hotel cancellation starts only when the user presses Approve in an e-mail from LetsFG, never from the conversation, and Hermes itself does not prompt before these tools unless you set `trust: untrusted` on the letsfg MCP server. Card details are only ever entered on letsfg.co, never in the conversation. Traveller details given for a booking (name, date of birth, gender, passport, contact, address) are sent to LetsFG and saved on that account. The server and its OAuth sign-in are added with `hermes mcp add letsfg --url https://letsfg.co/mcp --auth oauth --connect-timeout 300`.

How to install

  1. Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.
    hermes plugins install letsfg
  2. Said no? Turn it on later:
    hermes plugins enable letsfg
  3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see Full setup & settings. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide (opens in a new tab).
