Why teams choose Vinkius for TeleSign in OpenAI Agents SDK
The TeleSign 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 10 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.

TeleSign for OpenAI Agents SDK
Every tool call from OpenAI Agents SDK to the TeleSign MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Can my AI send and verify OTP codes?
Yes. send_verification sends the code, then check_verification validates the user's response.
Can I check fraud risk for a phone number?
Yes. score_phone returns a fraud risk score based on carrier intelligence and historical data.
Can I identify if a number is mobile or landline?
Yes. get_phone_type returns whether the number is mobile, landline, VoIP, or toll-free.
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.
