## Tasks (experimental)
> [!WARNING]
> The tasks API is experimental and may change without notice.
Task-based execution enables "call-now, fetch-later" patterns for long-running operations (see [Tasks](https://modelcontextprotocol.io/specification/latest/basic/utilities/tasks) in the MCP specification). Instead of returning a result immediately, a tool creates a task that can be polled or resumed later. To use tasks:
- Call {@linkcode @modelcontextprotocol/client!experimental/tasks/client.ExperimentalClientTasks#callToolStream | client.experimental.tasks.callToolStream(...)} to start a tool call that may create a task and emit status updates over time.
- Call {@linkcode @modelcontextprotocol/client!experimental/tasks/client.ExperimentalClientTasks#getTask | client.experimental.tasks.getTask(...)} and {@linkcode @modelcontextprotocol/client!experimental/tasks/client.ExperimentalClientTasks#getTaskResult | getTaskResult(...)} to check status and fetch results after reconnecting.
For a full runnable example, see [`simpleTaskInteractiveClient.ts`](https://github.com/modelcontextprotocol/typescript-sdk/blob/main/examples/client/src/simpleTaskInteractiveClient.ts).
