An installable Model Context Protocol server that gives AI agents native tools to send SMS, MMS and WhatsApp messages, manage contacts and webhooks, and research the Kudosity API — powered by Kudosity.
Runs locally (or in your own infrastructure), authenticates with your Kudosity API key, and exposes one clean tool per action — so an agent calls send_sms instead of hand-building HTTP requests.

Kudosity has two API surfaces, and this server uses each where it's authoritative:
| Tools | Auth | Credentials |
|---|---|---|
| Messaging, webhooks, discovery | x-api-key header |
KUDOSITY_API_KEY |
| Contact lists, balance | HTTP Basic | KUDOSITY_API_KEY + KUDOSITY_API_SECRET |
Credentials are read from environment variables and never written to disk. Treat them as secrets.
| Env var | Required | Default | Description |
|---|---|---|---|
KUDOSITY_API_KEY |
yes | — | Your Kudosity API key |
KUDOSITY_API_SECRET |
for contacts/balance | — | Your Kudosity API secret |
