Add a contact to a list, creating the contact if the number is new.

SimpleTexting MCP tools: https://cotlet.dev/docs/mcp/simpletexting.md

MCP tool: `simpletexting_write → add_contact_to_list`

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

Adds the number to the list and fills the name if you give it. An autoresponder set on that list fires when a contact joins, so adding a contact can send a text within minutes or after the autoresponder's delay. Returns the contact and its lists. Add only people who gave consent to be texted. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `list` | string | yes | Name of the contact list, from list_lists. |
| `contact_phone` | string | yes | Phone number, with country code. |
| `first_name` | string | no | First name. |
| `last_name` | string | no | Last name. |
