## Description

Uploads a log event to the specified log stream. [See docs](https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/clients/client-cloudwatch-logs/classes/putlogeventscommand.html)

## Props

| Prop | Type | Required | Description |
|---|---|---|---|
| `region` | `string` | Yes | The AWS region Options are loaded from the connected account. |
| `logGroupName` | `string` | Yes | The name of the log group Options are loaded from the connected account. |
| `logStreamName` | `string` | Yes | The name of the log stream for the chosen log group Options are loaded from the connected account. |
| `message` | `string` | Yes | The event message |
| `timestamp` | `integer` | Yes | The Unix timestamp for when the event occurred, in milliseconds |
| `sequenceToken` | `string` | No | The sequence token obtained from the response of the previous PutLogEvents call. An upload in a newly created log stream does not need a sequence token. You can also get the sequence token using DescribeLogStreams. If you call PutLogEvents twice within a narrow time period using the same value for sequenceToken, both calls might be successful or one might be rejected. |

## Run it

**MCP**

```ts
import { Client } from "@modelcontextprotocol/sdk/client/index.js"
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp.js"
import { PipedreamClient } from "@pipedream/sdk"

const pd = new PipedreamClient({
  projectId: process.env.PIPEDREAM_PROJECT_ID!,
  clientId: process.env.PIPEDREAM_CLIENT_ID!,
  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",
})

const accessToken = await pd.rawAccessToken

const transport = new StreamableHTTPClientTransport(
  new URL("https://remote.mcp.pipedream.net/v3"),
  {
    requestInit: {
      headers: {
        Authorization: `Bearer ${accessToken}`,
        "x-pd-project-id": process.env.PIPEDREAM_PROJECT_ID!,
        "x-pd-environment": "production",
        "x-pd-external-user-id": "{external_user_id}", // any stable ID for this user in your system
        "x-pd-app-slug": "aws",
      },
    },
  },
)

const mcp = new Client({ name: "my-agent", version: "1.0.0" })
await mcp.connect(transport)

const { tools } = await mcp.listTools()

// listTools() hands your model this tool's input schema, so it can
// fill the arguments itself:
const result = await mcp.callTool({
  name: "aws-cloudwatch-logs-put-log-event",
  arguments: {
    region: "AWS Region",
    logGroupName: "CloudWatch Log Groups",
  },
})
```

**TypeScript**

  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",
})

const result = await pd.actions.run({
  id: "aws-cloudwatch-logs-put-log-event",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    aws: { authProvisionId: "apn_xxxxxxx" },
