Create an opt-in keyword with a reply, optionally with a coupon.

Postscript MCP tools: https://cotlet.dev/docs/mcp/postscript.md

MCP tool: `postscript_write → create_keyword`

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

Uses Acquisition > Keywords > Create Keyword and Save Keyword. The name is visible to subscribers. With a coupon, Postscript's Include coupon in reply is turned on with a percent or dollar amount; without one, the reply is added as an action. Anyone who texts the word is added to your SMS list and gets the reply, so it reaches people. More than two keywords need the Growth, Professional or Enterprise plan. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `keyword` | string | yes | The word people text, for example VIPACCESS. |
| `reply` | string | no | Reply text sent after opt-in. |
| `coupon_type` | enum | no | percent or amount. Leave out for no coupon. |
| `coupon_value` | number | no | Percent or dollar amount of the coupon. |
