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.

```bash
hermes plugins install letsfg
```

2. Said no? Turn it on later:

```bash
hermes plugins enable letsfg
```

3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see the official page. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide: https://hermes-agent.nousresearch.com/docs/user-guide/features/plugins
