SMS and WhatsApp Messaging MCP server

• check_complianceFree

  Free, instant pre-flight for the compliance gate. Runs the SAME TCPA / GDPR / CASL / CAN-SPAM / 10DLC gate that send_message and call_business run — but in preview mode, so NO message is sent and NO state changes. Tells you whether a (recipient, channel, message_type, content) send would be permitted BEFORE you pay for it, and if not, names the exact rule and how to remediate. Use it to de-risk a paid send the same way check_booking_link… [free, no key]

• find_businessFree

  Given criteria (vertical, location, capability, price band, availability window), return ranked candidate businesses from our supply network. THE NETWORK IS SMALL AND STILL MOSTLY SAMPLE DATA: entries that are not real are named [DEMO] and flagged is_demo - check that field before acting on a result. [free, no key]

• get_conversationFree

  Read a two-way conversation thread you started: its state, every message exchanged, and how many replies the business has sent. [free, no key]

• get_outcomeFree

  Retrieve the final OutcomeReceipt for a completed operation. [free, no key]

• get_statusFree

  Query the current state of any in-flight async operation by operation_id. [free, no key]

• preview_costFree

  Return an expected cost estimate, latency estimate, and success-probability estimate for a proposed call before execution. Returns the exact price when it is fixed, and a min/max range when the cost depends on channel or outcome. It does not promise an accuracy percentage - check cost_range. [free, no key]

• self_testFree

  Service health probe: runs 6 internal checks and reports how many passed. Confirms the server is up and responding - it does NOT probe each tool individually. Use to verify connectivity before production use. [free, no key]

• send_messagewrite actionFree

  Send a message on behalf of an agent's user or an SMB across WhatsApp (free during launch), SMS, email, or voice. Five message types: transactional, reminder, follow_up, notification, marketing. Every send routes through a non-bypassable compliance gate (TCPA, GDPR, CASL, PDPL across 26 jurisdictions) that enforces opt-in consent for marketing/promotional content — marketing without recorded consent is rejected at runtime with a structured… [from $0.02/call, variable] [async→get_outcome]

• send_transactional_confirmationwrite actionFree

  Idempotent transactional messages: OTPs, booking confirmations, payment receipts, cancellation notices. Falls back across configured channels; an unconfigured channel fails honestly rather than reporting a delivery that did not happen. [$0.02/per_call] [async→get_outcome]

• verify_businessFree

  Look up what we know about a business in our supply network: its contact channels, capabilities, and when the record was last verified. This is a DIRECTORY LOOKUP - it does not contact the business. [free, no key]
