We’re excited to announce the release of the SignalWire Agents SDK—a Python-native toolkit that makes it faster and easier to build real-time AI voice agents with built-in support for SIP, PSTN, WebRTC, and messaging.No more piecing together APIs or handling telecom complexity. With the Agents SDK, you can:

• Build AI agents using familiar Python tools

• Run AI Agents as microservices, Lambdas, or CGI scripts—your choice

• Add skills like search, knowledge lookups, or custom tool calls with one line of code

• Deploy production-ready agents with ultra-low latency (~500ms globally)

• Use tools built for Model Context Protocol (MCP), an emerging standard for defining AI tool interfaces, without rewriting them.

Whether starting from scratch or scaling a mature voice AI application, the Agents SDK lets you focus on building great conversations, not wiring up infrastructure. No SIP expertise required, just bring your Python skills.
