# Function: resultOf()

> **resultOf**(`outcome`): `object`

Defined in: [packages/mcp/src/mcp.ts:101](https://github.com/ufo-soft/caelus/blob/31cc32fc3d2008e3b0d484d65d10bba2a91a5897/packages/mcp/src/mcp.ts#L101)

An Outcome as a tool result: ok is one text block, failed is the reason marked as an error.
A tool result needs some text, so no data says "ok" where the CLI prints nothing.

## Parameters

### outcome

[`Outcome`](../../caelus/core/type-aliases/Outcome.md)

## Returns

`object`

### \_meta?

> `optional` **\_meta?**: `object`

#### Index Signature

#### \_meta.io.modelcontextprotocol/related-task?

> `optional` **io.modelcontextprotocol/related-task?**: `object`

If specified, this request is related to the provided task.

#### \_meta.io.modelcontextprotocol/related-task.taskId

> **taskId**: `string`

#### \_meta.progressToken?

> `optional` **progressToken?**: `string` | `number`

If specified, the caller is requesting out-of-band progress notifications for this request (as represented by notifications/progress). The value of this parameter is an opaque token that will be attached to any subsequent notifications. The receiver is not obligated to provide these notifications.
