MCP Dev Summit Bengaluru 2026

Every MCP demo assumes text in and text out. This talk explores what actually happens when you replace the text interface with a live voice stream.
Connecting a real-time voice pipeline to an MCP-backed agent introduces problems that the current MCP ecosystem has no established answers for. This talk walks through them one by one: end-of-turn detection and how tool-calling latency affects perceived conversational fluency, interruption handling when a user speaks while a tool is executing, tool result verbalization where structured JSON responses need to be narrated naturally without losing meaning, and error communication when a tool fails mid-conversation.
The talk is grounded in a working system built with a real-time voice layer, Sarvam AI for speech processing, and MCP-connected agents handling live tool calls. Attendees will see a live demo and leave with an architectural blueprint for voice-first MCP agents, including the specific latency budgets, buffering strategies, and verbalization patterns that make the experience feel natural rather than robotic.
This is a frontier that very few builders have shipped in production.
