Voodoo SMS MCP by usefulapi

WRITE: adds one number to the account's opt-out blacklist; from then on no SMS is sent to it (sends to it fail with error 20). Use it for a recipient who asked to stop. This tool cannot remove a number again. Voodoo SMS REST: POST /blacklist.

WRITE: cancels one SMS that was scheduled through the send API, so it will not be sent. A message that has already gone out cannot be cancelled. Whether credits are refunded for a cancelled message is not documented by the vendor. Voodoo SMS REST: DELETE /schedule/{id}.

WRITE: creates a new contact list with up to 500 contacts (the list name must be unique, at most 32 characters). It does not send anything. Voodoo SMS REST: POST /contacts.

Get one contact list including its contacts (id, number, status, dynamic_data, created_at). Voodoo SMS REST: GET /contacts?contact_list_id=.

Get the SMS credit balance of the account. One credit pays for one 160-character SMS part (153 characters per part in a long message). Voodoo SMS REST: GET /credits.

List the numbers on the account's opt-out blacklist (no SMS is ever sent to them), or look up one number (`{empty: true}` means it is not on the list). Returns an empty result when the blacklist is empty. Voodoo SMS REST: GET /blacklist.

List the account's contact lists (id, name, status, size, created/updated times) without their contacts. Returns an empty result if there are none. Voodoo SMS REST: GET /contacts.

List delivery reports of sent messages (message_id, sender_id, to, sent_at, delivered_at, price, status), optionally filtered. Use it to check whether a message was delivered. Dates accept a UNIX timestamp, ISO 8601 (2026-10-01T09:00:00+00:00) or plain English ('yesterday', '2 weeks'). Voodoo SMS REST: GET /report.

List SMS received on the account's Virtual Mobile Numbers (replies and keyword messages). Needs a purchased number; an empty inbox returns an empty result. Dates accept a UNIX timestamp, ISO 8601 or plain English. Voodoo SMS REST: GET /inbox.

List the Virtual Mobile Numbers (VMNs) the account has purchased, used to receive SMS. Returns an empty result if there are none. Voodoo SMS REST: GET /numbers.

List SMS that were scheduled through the send API and are still waiting to go out (messages scheduled in the portal's Web SMS are not shown). Voodoo SMS REST: GET /schedule.

WRITE: SENDS A REAL SMS to ONE recipient and USES THE ACCOUNT'S CREDITS (1 credit per message part, charged whether or not it is delivered; it cannot be undone). `sandbox` is required: true validates and prices the message without sending or charging, false sends it for real. Optional `schedule` queues it for later (cancel with cancel_scheduled_message). Do not retry after an error or timeout without checking list_delivery_reports / list_scheduled_messages, or the recipient may get it twice. One recipient per call; there is no bulk or list send. Voodoo SMS REST: POST /sendsms.

WRITE: renames a contact list and/or adds up to 500 contacts to it (existing contacts are not removed). Adding dynamic data needs a list created as dynamic. It does not send anything. Voodoo SMS REST: PUT /contacts/{contact_list_id}.
