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.

Tools

Messaging

• For contact and balance tools, also your API secret (same settings page)

Install & configure

Runs via npx — no clone required.

Claude Desktop / Claude Code

{
  "mcpServers": {
    "kudosity": {
      "command": "npx",
      "args": ["-y", "kudosity-mcp"],
      "env": {
        "KUDOSITY_API_KEY": "your_api_key",
        "KUDOSITY_API_SECRET": "your_api_secret"
      }
    }
  }
}

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.

• "List my delivered SMS from the last day." / "Show me inbound SMS replies."
• "Create a contact list called VIPs and add 61438333061."
• "Register a webhook at https://example.com/hook for SMS delivery status."
• "What's my account balance?"
• "Search the Kudosity API for anything about opt-outs."

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

Local development

git clone https://github.com/kudosity/mcp
cd mcp
