Change answers in a submission, like Edit and Update Submission in Results.

123FormBuilder MCP tools: https://cotlet.dev/docs/mcp/123formbuilder.md

MCP tool: `123formbuilder_write → update_submission`

Access: write. Confirm: waits for the user's OK before it runs.

Edits the data a respondent provided, field by field, and saves it. Fields you leave out stay as they are; a label that is not on the form fails. The default report updates by itself, custom reports need an Update click in the app. Respondents are not told by default. If the form resends notifications on edit, the app sends them when the entry is saved, and notifications_resent is true. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `form_id` | integer | yes | Form id from list_forms. |
| `submission_id` | integer | yes | Submission id from list_submissions. |
| `values` | object | yes | Field label to new value, for the fields you change. |
