BulkSMS MCP by usefulapi

Block a phone number

bulksms_block_number
DestructiveIdempotent

WRITE: adds ONE phone number to the account's blocked list, so that no further messages are sent to it (a send to a blocked number fails with FAILED.BLOCKED and still costs credits). This API has no way to remove a block again: do it only when the user asks for it. BulkSMS REST: POST /blocked-numbers.
