# IndexedDBStore

Defined in: [client/browser-stores.ts:40](https://github.com/PrefectHQ/fastmcp-ts/blob/8976c37f79efa6b87809b884f29a1f235a8c4ad1/src/client/browser-stores.ts#L40)

KeyValueStore backed by IndexedDB. Preferred when tokens should survive

stricter persistence). Opens the database per operation and closes it again.
