Authentication

Auth type	No authentication

The sign-in route, step by step

Send the handshake to https://hotels.flightpowers.com/mcp over streamable-http. Servers on the 2026-07-28 revision answer server/discover; older servers answer initialize.
Send tools/list, then resources/list and prompts/list if the capabilities name them.
Send no token. The connector sent none and the server answered, so any MCP client can read this list.
Calling a tool is a separate step this directory never takes.

See OAuth for MCP: client ID metadata documents and dynamic registration for how each route works.

CLI

No CLI is on record for Flightpowers. The directory checks a package only where a source names one, so this is a floor: a company can ship a command line that no source read for this edition mentions. See shipping a CLI agents can use.
