SMS and WhatsApp Messaging does not always answer
Over the last week it answered 90.3% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

send
send_message
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_confirmation
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]
business
find_business
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]
compliance
check_compliance
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]
conversation
get_conversation
Read a two-way conversation thread you started: its state, every message exchanged, and how many replies the business has sent. [free, no key]
outcome
get_outcome
Retrieve the final OutcomeReceipt for a completed operation. [free, no key]
preview
preview_cost
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
self_test
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]
status
get_status
Query the current state of any in-flight async operation by operation_id. [free, no key]
verify
verify_business
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]

SMS and WhatsApp Messaging — questions
Answers built from our own checks of this server.
What can SMS and WhatsApp Messaging do?
It exposes 10 tools, read directly from the server on our last check. Among them: check_compliance, find_business, get_conversation, get_outcome, get_status, preview_cost and 4 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
Is SMS and WhatsApp Messaging working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 77 of 93 checks got a reply (82.8%), average response time 797 ms. The bar chart above shows every period we have measured.
How do I connect SMS and WhatsApp Messaging?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does SMS and WhatsApp Messaging need an API key?
No. SMS and WhatsApp Messaging completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 10 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is SMS and WhatsApp Messaging?
It answers our handshake in 797 ms on average, which is faster than 15% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is SMS and WhatsApp Messaging open source?
Yes — it is published under the MIT licence, written in Python, 1 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
