# CompletionContext

Defined in: [server/completion.ts:24](https://github.com/PrefectHQ/fastmcp-ts/blob/8976c37f79efa6b87809b884f29a1f235a8c4ad1/src/server/completion.ts#L24)

has already resolved for the prompt's OTHER arguments (or the template's other
variables). Use it to narrow suggestions — e.g. offer cities once a country is
chosen.

## Properties
