> The Implementation Verbs update, delete as MCP do programs, with inputs, result, refusals and an example.

Reference for [Implementation](/business/nouns/implementation), one group of [Implementation programs](/code/mcp/implementation).

### Implementation.update
Changes the given properties of an Implementation. [Verb page](/business/nouns/implementation/update?interface=mcp).

```text
do: return await $.Implementation.update(input)
```

Emits `Implementation.updated`.

**Inputs**

| Input | Type | Required | Description |
| --- | --- | --- | --- |
| `id` | `string` | Yes | The id of the Implementation. |
| `kind` | `string` | No | One of `managed`, `custom`, or `external`. |
| `endpoint` | `url` | No | For an external Implementation, where api.sb routes each call. |
| `deliverBy` | `date` | No | For a `declared` Implementation: when a Function runs the Verb; a missed date refunds every reserve. |
