Kudosity MCP Server
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.
Messaging
| Tool | Type | Description |
|---|
send_sms | write | Send an SMS to a recipient |
send_mms | write | Send an MMS with a media attachment |
send_whatsapp | write | Send a WhatsApp message (free-form text or approved template) |
get_message | read | Get a sent message and its status by channel + ID |
list_messages | read | List sent/received messages with delivery status; filter by status, direction (sent/replies), recipient, dates |
Webhooks
| Tool | Type | Description |
|---|
create_webhook | write | Register an HTTPS webhook for delivery status, inbound messages, link hits, opt-outs |
list_webhooks | read | List configured webhooks |
delete_webhook | write | Delete a webhook by ID |
Contacts & lists (require KUDOSITY_API_SECRET)
| Tool | Type | Description |
|---|
create_list | write | Create a contact list |
get_lists | read | List all contact lists |
get_list | read | Get a list and optionally its members |
add_contact_to_list | write | Add a contact to a list |
remove_contact_from_list | write | Remove a contact from a list |
delete_list | write | Delete a contact list |
Account (requires KUDOSITY_API_SECRET)
| Tool | Type | Description |

get_balance | read | Get your account balance |
API discovery — research the whole Kudosity API, always current
| Tool | Type | Description |
|---|
list_specs | read | List the Kudosity API specifications |
list_endpoints | read | List all endpoints for a spec |
search_endpoints | read | Search the API by keyword |
get_endpoint | read | Get full detail for one endpoint |
The discovery tools read the live specs from developers.kudosity.com, so they always reflect the latest published docs.
Requirements
- Node.js 18+
- A Kudosity account and API key — Settings → API Settings in the Kudosity platform
- For contact and balance tools, also your API secret (same settings page)
Runs via npx — no clone required.

}
KUDOSITY_API_SECRET is optional — omit it if you only need messaging, webhooks, and discovery. It's required for the contact-list and balance tools.

Authentication
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.
Configuration
| Env var | Required | Default | Description |
|---|
KUDOSITY_API_KEY | yes | — | Your Kudosity API key |
KUDOSITY_API_SECRET | for contacts/balance | — | Your Kudosity API secret |
KUDOSITY_API_BASE_URL | no | https://api.transmitmessage.com | Override the v2 API base URL |
KUDOSITY_V1_BASE_URL | no | https://api.transmitsms.com | Override the v1 API base URL |
