What is the Mitto MCP Server?
Connect your Mitto account to any AI agent to handle global communication workflows through natural conversation.
What you can do
- SMS Messaging — Send single or bulk SMS messages globally with custom sender IDs and delivery tracking.
- Two-Factor Authentication (2FA) — Generate, send, and verify OTP codes via SMS or Voice channels to secure your user accounts.
- 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
- Subscribe to this server
- Enter your Mitto API Key

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.

Mitto in OpenAI Agents SDK
Mitto and 4,000+ other MCP servers. One platform. One governance layer.
Teams that connect Mitto to OpenAI Agents SDK through Vinkius don't need to source, host, or maintain individual MCP servers. Every tool call runs inside a hardened runtime with credential isolation, DLP, and a signed audit chain.

Why teams choose Vinkius for Mitto in OpenAI Agents SDK
The Mitto MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 27 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in OpenAI Agents SDK only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

* Every MCP server runs on Vinkius-managed infrastructure inside AWS - a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts optimized for native MCP execution. See our infrastructure
How Vinkius secures
Mitto for OpenAI Agents SDK
Every tool call from OpenAI Agents SDK to the Mitto MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
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.
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.
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.
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.
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.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
