A hosted MCP server that gives AI agents tools for SMS, voice calls, and phone verification. It connects directly to telephony routes without local hosting.

## What it does

The server operates remotely over stateless HTTP at `https://packetexchange.io/mcp/http`. No local build is needed. It provides 33 tools, split between 15 marketplace and account utilities and 18 Switch tools for managing carriers, routing, and billing.

Calling features include speech synthesis in six languages, audio playback, and DTMF keypad digit collection through `wmmn_make_call`. Text messaging via `wmmn_send_sms` reports the gateway submission state immediately, while final handset delivery status is queried through external REST webhooks.

Unauthenticated sessions can only access three discovery tools. Any billed action requires an account with prepaid credits and an `Authorization: Bearer <API key>` header set in your client configuration. Using test keys prefixed with `wmmn_test_sk_` simulates traffic without spending balance, but blocks Switch modifications.
