Wavix MCP Server

A Model Context Protocol server that gives LLMs and AI agents direct access to the Wavix telecom platform — SMS/MMS, voice calls, 2FA, SIP trunking, phone-number management, 10DLC registration, call recordings, speech analytics, and billing.

Wavix is a global communications platform for sending SMS, placing voice calls, and running 2FA flows over a single API. A free trial is available; paid usage follows the Wavix pricing plan attached to your account.

The fastest way to use this MCP server is the hosted endpoint at https://mcp.wavix.com/mcp — point any MCP-compatible client at it and authenticate with your Wavix API key. If you need to self-host (custom Wavix deployment, behind a firewall, dedicated instance), see Run your own.

Endpoint

| Field | Value | | --- | --- | | URL | https://mcp.wavix.com/mcp | | Transport | Streamable HTTP | | Auth | Authorization: Bearer <api_key> | | Tools | see TOOLS.md | | Resources | Wavix docs + OpenAPI spec (auto-discovered) |

Get a Wavix API key from the Wavix Console → Administration → API keys → Create new.

Install

Before you start: grab your Wavix API key.

1. Sign in at https://wavix.com.
2. Open Administration → API keys.
3. Click Create new (or copy an existing key). Keep it handy — you'll paste it in place of YOUR_API_KEY below.

One-click install

⚠️ The buttons below seed your editor's MCP config with a placeholder token YOUR_API_KEY. After the editor finishes installing, open the generated config and replace the placeholder with your real API key before sending any request — otherwise every call will return 401 Unauthorized.

To remove later: open the same config file (~/.cursor/mcp.json, .vscode/mcp.json, or the equivalent for your editor) and delete the wavix entry, or remove the connector through your editor's MCP / Connectors UI.

Claude Code

claude mcp add --transport http wavix https://mcp.wavix.com/mcp \
  --header "Authorization: Bearer YOUR_API_KEY"

Use claude mcp list to verify and /mcp inside a session for status.

Claude Desktop / Claude Web

Settings → Connectors → Add custom connector:

• Name: Wavix
• URL: https://mcp.wavix.com/mcp
• Transport: Streamable HTTP
• Authentication header: Authorization: Bearer <api_key>

Cursor (manual)

Add to ~/.cursor/mcp.json (or project-level .cursor/mcp.json):

{
  "mcpServers": {
    "wavix": {
      "url": "https://mcp.wavix.com/mcp",
      "headers": {
        "Authorization": "Bearer <api_key>"
      }
    }
  }
}

Cursor 2.4+ exposes the full catalogue; earlier versions cap at 40.

VS Code (manual, GitHub Copilot Chat)

Create .vscode/mcp.json in your workspace (or add the same servers object under the "mcp" key in user settings.json):

{
  "servers": {
    "wavix": {
      "type": "http",
      "url": "https://mcp.wavix.com/mcp",
      "headers": {
        "Authorization": "Bearer <api_key>"
      }
    }
  }
}

See the VS Code MCP servers guide for the up-to-date schema.

Codex CLI

Codex CLI supports MCP over stdio. Bridge to the hosted server via mcp-remote. Edit ~/.codex/config.toml:

[mcp_servers.wavix]
command = "npx"
args = [
  "-y",
  "mcp-remote",
  "https://mcp.wavix.com/mcp",
  "--header",
  "Authorization:Bearer ${WAVIX_API_KEY}"
]

[mcp_servers.wavix.env]
WAVIX_API_KEY = "YOUR_API_KEY"

Windsurf / other clients

Any MCP client that supports Streamable HTTP transport with custom headers will work. Use:

• URL: https://mcp.wavix.com/mcp
• Header: Authorization: Bearer <api_key>

Setting up via an AI agent? Point your agent at llms-install.md — it's a machine-readable install guide that gives the model the URL, header, and per-client configuration in a deterministic format so it doesn't improvise endpoint values.

Run your own

The hosted server works out of the box for most users. Self-host if you need to point at a non-public Wavix deployment, run behind a firewall, or operate inside your own infrastructure.

Docker

docker build -t wavix-mcp-server .
docker run --rm -p 8000:8000 wavix-mcp-server

The server listens on port 8000 and exposes the MCP endpoint at /mcp. Point your client at http://<host>:8000/mcp.

From source

git clone https://github.com/Wavix/wavix-mcp-server.git
cd wavix-mcp-server
pip install -e .
wavix-mcp

Requires Python 3.10+.

Configuration

| Env var | Default | Purpose | | --- | --- | --- | | WAVIX_API_BASE_URL | https://api.wavix.com | Override the upstream Wavix API endpoint (for internal deployments or staging) |

No Wavix credentials are required to run the server — they are forwarded per-request from the MCP client's Authorization: Bearer <api_key> header. Self-hosters are responsible for terminating TLS in front of the server (nginx, Caddy, cloud load balancer) before exposing it publicly.

Examples

Concrete prompts you can drop into any connected client.

Phone numbers below (+1 310 555 0100, +44 7700 900123) are in reserved test ranges (NANP 555 and Ofcom 070 09xx) — safe to copy verbatim, no real subscribers are reachable through them.

Send a transactional SMS

Prompt: "Send an SMS from +13105550100 to +447700900123 saying 'Your verification code is 4821'."

The agent calls sms_and_mms_messages_send with from, to, and text. Returns the message ID and delivery status.

Run a 2FA verification

Prompt: "Send a 2FA verification code to +13105550100 via SMS. When I give you the code I receive, check whether it's correct."

The agent calls two_fa_verification_create, waits for you to share the code that arrives via SMS, then calls two_fa_verification_check. Useful for prototyping passwordless flows without writing integration code.

Find and buy a phone number

Prompt: "Find an available US toll-free number with SMS capability, add it to my cart, and check out."

The agent chains buy_numbers_list (filtering by country and feature), cart_add, and cart_checkout. Confirm with the user before checkout — it charges the account.

Search call transcripts

Prompt: "Show me all inbound calls from yesterday longer than two minutes where the caller mentioned 'refund'."

The agent uses cdrs_search against transcriptions, then enriches each result via cdrs_get for full call metadata.

Pull a recording and transcribe it

Prompt: "Get the recording for call abc-123, ask Wavix to transcribe it, and return the transcription."

The agent calls call_recording_get (returns a pre-signed download URL), cdrs_retranscribe, then polls cdrs_transcription_get.

Audit billing

Prompt: "How much did we spend on SMS last month? Give me a download link for the most recent invoice PDF."

The agent calls billing_transactions_list filtered by type and date, then billing_invoices_list + billing_invoices_download. The download tool returns a pre-signed URL to the PDF, not the file itself — open the URL in a browser or pass it to your client to fetch the actual document.

See TOOLS.md for the complete tool list with one-line descriptions. The authoritative source is the Wavix OpenAPI spec — your client always sees the current live catalogue.

Resources

In addition to tools, the server exposes Wavix documentation as MCP Resources, so the model can pull authoritative context on demand instead of guessing from prior knowledge.

| URI scheme | Contents | | --- | --- | | wavix://docs/<path> | Documentation pages from docs.wavix.com (auto-discovered via llms.txt). | | wavix://api/openapi.yaml | The full Wavix OpenAPI 3.0 specification. |

Both sources — docs.wavix.com and the Wavix OpenAPI spec — are publicly available and can be browsed directly without authentication.
