Purchase Phone Number

Billable - retry unsafe Purchases a phone number from Plivo and registers it to the organization. This is NOT a read-only action — it spends real money from the organization’s wallet immediately. Use search_plivo_numbers first to find an available number and its telephony_provider_id. Requires confirm: true — only set this after the user has explicitly approved buying this specific number, never preemptively.

Parameters

Name	Type	Required	Description
`phone_number`	`string`	Yes	The phone number to purchase, e.g. +14155551234
`telephony_provider_id`	`string`	Yes	The telephony provider ID from search_plivo_numbers
`country_iso`	`string`	Yes	2-letter country ISO code, e.g. US, IN
`confirm`	`boolean`	Yes	Must be true. Set this only after the user has explicitly approved purchasing this specific number.

Before you call

Connect and initialize the MCP client with OAuth or an API key for the intended workspace.
Provide the required parameters: phone_number, telephony_provider_id, country_iso, confirm.
Set confirm: true only after the user approves the exact target and action.

Example MCP request

Send tools/call after your client completes MCP initialization. Replace placeholder values with IDs and inputs from your workspace. For object and array parameters, follow the nested requirements in the parameter description instead of treating an empty value as complete.

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "purchase_phone_number",

}

The server returns one text content block. Parse content[0].text as JSON when the tool succeeds. See MCP responses and errors for the full envelope and failure behavior.

Verify the result

Store the returned resource ID and confirm the response is not marked isError. Call Search Plivo Numbers to read the affected resource. Verify the call, batch, or purchase state before retrying.

Retry safety

This tool can spend wallet balance or start real calls. After a timeout, inspect the relevant resource before retrying so you do not duplicate the action.
