Is this an official Vonage MCP server?

No. It is Memtro's MCP server with Memtro's Vonage connector behind it: the connector reads Vonage through its API with the credentials you connect on Dashboard → Connections, and Vonage publishes nothing here. The same endpoint carries every other system you connect and Memtro's memory tools.

Nothing on top of Memtro. One price per organisation by its number of users, from $50 a month for up to 10 users after a 7-day free trial, with every connector, the MCP server, jobs and memory included. You bring your own model keys.

Can it change anything in Vonage?

Only when you ask, and only what it has been granted: send an SMS from the account to one number (spends account credit; the recipient is texted); send a verification code by SMS or voice to a number (spends account credit); check a verification code a person entered; cancel (release) a phone number the account owns (permanent; inbound calls and texts stop). Every other tool reads, searches or lists. An administrator grants each acting tool by name per team, and a personal connection acts only after its owner allows it.

Any MCP client that speaks Streamable HTTP: Claude Code, Cursor, Claude Desktop, OpenCode, Codex, Zed, Windsurf, Cline and the Anthropic and OpenAI SDKs. There is no local process to run; the server is remote and authenticated with your key.

Vonage MCP server

Vonage in any MCP client, through Memtro: Vonage does not publish this server. Memtro's Vonage connector reads Vonage through its API with the credentials you connect, and one endpoint hands those tools, every other system you connect and Memtro's memory tools to Claude Code, Cursor, Claude Desktop or anything else that speaks Streamable HTTP, as you.

What the model can do

Vonage Communications APIs: account balance (EUR), the phone numbers the account owns with their features and linked application, applications and their capabilities, and outbound SMS and voice prices by country and network. Can send an SMS, send and check a Verify code, and cancel (release) an owned number.

Reads

vonage_get_balanceThe Vonage account's remaining credit, in EUR, and whether auto-reload is on.
vonage_list_numbersPhone numbers the account owns: number, country, type (landline, mobile, toll-free), features (SMS, voice, MMS) and the application each is linked to.
vonage_list_applicationsVonage applications (what voice, messages and other capabilities each one has), with ids that numbers are linked to.
vonage_get_pricingWhat Vonage charges to send an SMS or make a voice call to one country: the default price, currency and the price per mobile network.

Acts, when you ask

These change something in Vonage. The model is told to use them only when you ask for exactly that, and each one is granted by name: per team on a shared connection, by the owner on a personal one.

vonage_send_smsSend one SMS from the Vonage account to one phone number, from a sender id (up to 11 letters or digits) or one of the account's numbers.
vonage_start_verificationSend a verification code to a phone number with Vonage Verify (v1): by SMS, then a voice call if not used…
vonage_check_verificationCheck the code a person entered against a Vonage Verify request (by request_id).
vonage_cancel_numberCancel the account's subscription to one of its phone numbers (release it).

Connect it

First connect Vonage on Dashboard → Connections, then add Memtro to your client once. The Vonage tools appear alongside the tools of everything else you have connected; nothing is configured per connector.

Claude Code

The Memtro plugin registers the server and a skill for when to use it; the tools are then available in every session.

claude plugin marketplace add memtro-org/claude-memtro
claude plugin install memtro@memtro --config api_key=sk-memtro-...

Cursor

Add the server to .cursor/mcp.json in the project, or to the global file under ~/.cursor/.

{
  "mcpServers": {
    "memtro": {
      "url": "https://platform.memtro.com/api/mcp",
      "headers": {
        "Authorization": "Bearer sk-memtro-..."
      }
    }
  }
}

Claude Desktop

Create a personal API key on Dashboard → Profile → API keys. In Claude Desktop add an MCP server of type HTTP with URL https://platform.memtro.com/api/mcp and the header Authorization: Bearer sk-memtro-…

OpenCode

A remote server in opencode.json.

{
  "mcp": {
    "memtro": {
      "type": "remote",
      "url": "https://platform.memtro.com/api/mcp",
      "headers": {
        "Authorization": "Bearer sk-memtro-..."
      }
    }
  }
}

Pi

One command: pi mcp add memtro --url https://platform.memtro.com/api/mcp --bearer-token-env-var MEMTRO_API_KEY. Tools arrive as mcp__memtro__*. The pi-memtro extension registers it for you, alongside Memtro as the model.

Any other client

Add an MCP server of type HTTP (Streamable HTTP, stateless) at https://platform.memtro.com/api/mcp with the header Authorization: Bearer sk-memtro-.... Codex, Zed, Windsurf, Cline and the SDKs all take a remote server this way.

Who may use it

The key identifies the person, and the server offers that person the tools they may use everywhere else in Memtro. A shared Vonage connection is used by the teams an administrator granted it to, tool by tool, on the Permissions page; a personal connection is used by its owner alone, and its tools that act stay off until the owner allows them. See Teams and permissions and Connectors.
