MCP tool: `accounting_data_sources_pin`

## Fields

| Field | Type | Required | Notes |
| --- | --- | --- | --- |
| `source` | enum | Yes | Where the record came from. One of: `notion`, `google_drive`, `onedrive`. |
| `databaseId` | string | Yes | 1–200 characters; Matches ^[A-Za-z0-9_.:-]+$. |
| `pinned` | boolean | Yes |  |
| `idempotencyKey` | string | Yes | Any unique text you generate once per intended change, so a retried request only happens once. Send it as the Idempotency-Key header instead if you prefer; if you send both they must match. 8–200 characters. |
