## Description

Records a single log entry or event in Logfire as a zero-duration span, via OTLP ingestion. Use this whenever the user wants to log, record, or note an event, deployment, incident, or error — this is Logfire's equivalent of calling `logfire.info()`/`logfire.error()` from the SDK. This creates a single point-in-time entry, not a full distributed trace with parent/child spans. Setting `exceptionType`/`exceptionMessage` marks the entry as an exception (`is_exception = true` when later queried). After recording, use **Run SQL Query** to confirm what was written (e.g. `SELECT * FROM records WHERE message LIKE '%...%' ORDER BY start_timestamp DESC LIMIT 1`). [See the documentation](https://pydantic.dev/docs/logfire/reference/sql/)

## Props

| Prop | Type | Required | Description |
|---|---|---|---|
| `message` | `string` | Yes | The log message to record, e.g. Deployment v2.4.1 went out successfully. |
| `level` | `string` | No | The severity level of the log entry. |
| `spanName` | `string` | No | A short name for the span, used to group similar entries. Defaults to the message if not provided. |
| `serviceName` | `string` | No | The name of the service this log entry is attributed to. |
| `attributes` | `string` | No | Optional JSON object of additional key-value attributes to attach to the entry. Example: {"customer_id": "12345", "region": "us-east"}. |
| `exceptionType` | `string` | No | If this entry represents an exception, the exception's type/class name, e.g. ValueError. |
| `exceptionMessage` | `string` | No | If this entry represents an exception, the exception's message. Setting this (with exceptionType) marks the span as an exception in Logfire. |

  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(

  },
)

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: "logfire-record-log-entry",
  arguments: {
    message: "Message",
    level: "Level",
  },
})
```
