SMS and WhatsApp Messaging is an MCP server with 10 tools an agent can call, among them check_compliance, find_business, get_conversation. It answers at https://hatchloop.dev/mcp/sms-whatsapp-messaging over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 10 September 2026; the last check, on 19 October 2026, succeeded.
Send WhatsApp, SMS, email or voice to a business with the compliance gate enforced.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
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.

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] Inputs: conversation_id, reference, business_number |
get_outcome | Retrieve the final OutcomeReceipt for a completed operation. [free, no key] Inputs: operation_id |
get_status | Query the current state of any in-flight async operation by operation_id. [free, no key] Inputs: operation_id |
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 no Inputs: operation, params |
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] |
send_message | Send a message on behalf of an agent's user or an SMB across WhatsApp (free during launch), SMS, email, or voice.

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] Inputs: smb_id, capability_to_verify |

It answered our last check on 19 October 2026 in 659 ms. Over 6 checks since 10 September 2026 it answered 6. Status here comes from Neuronto's own probes, not from the publisher.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://hatchloop.dev/mcp/sms-whatsapp-messaging. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
