  • Number Lookup — Validate phone numbers and retrieve carrier information to ensure deliverability.
  • Usage Analytics — Monitor your SMS and 2FA usage statistics grouped by country or date ranges.
  • Application Management — Manage your Mitto applications and masked numbers for privacy-focused communication.

How it works

  1. Subscribe to this server
  2. Enter your Mitto API Key
  3. Start sending messages and verifying users from Claude, Cursor, or any MCP-compatible client

Who is this for?

Why OpenAI Agents SDK?

The OpenAI Agents SDK auto-discovers all 27 tools from Mitto through native MCP integration. Build agents with built-in guardrails, tracing, and handoff patterns. chain multiple agents where one queries Mitto, another analyzes results, and a third generates reports, all orchestrated through Vinkius.

  • Native MCP integration via MCPServerSse, pass the URL and the SDK auto-discovers all tools with full type safety

  • Built-in guardrails, tracing, and handoff patterns let you build production-grade agents without reinventing safety infrastructure

  • Lightweight and composable: chain multiple agents and MCP servers in a single pipeline with minimal boilerplate

  • First-party OpenAI support ensures optimal compatibility with GPT models for tool calling and structured output

FAQ

Frequently asked questions

01

Can I send an SMS to multiple phone numbers at the same time?

Yes! Use the send_bulk_sms tool. You can provide an array of recipient numbers in E.164 format and a single message body to reach multiple users at once.

02

How do I verify a security code sent to a user?

After sending a code with send_2fa, use the verify_2fa tool. You will need the requestId from the initial send and the code provided by the user to confirm their identity.

03

Can I check which countries I am sending the most messages to?

Yes, the get_sms_usage_by_country tool allows you to retrieve usage statistics grouped by country, helping you analyze your global communication reach.

04

How does the OpenAI Agents SDK connect to MCP?

Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.

05

Can I use multiple MCP servers in one agent?

Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.

06

Does the SDK support streaming responses?

Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.

07
