MCP Dev Summit Bengaluru 2026

MCP's tool schema, server descriptions, and routing logic are overwhelmingly designed around English. That assumption quietly breaks when you build for users in Hindi, Tamil, Kannada, or Bengali.
This talk is a ground-up look at where MCP falls short for Indic language users and what it takes to fix it. The specific failure modes covered include: intent ambiguity in tool selection when queries arrive in transliterated or code-switched text, embedding models trained on English producing poor similarity scores for Indic-language tool descriptions, and response localization gaps where tool results are returned in English to users who queried in their native language.
The talk then presents concrete patterns for each problem, including translated and dual-language tool manifests, language-aware routing layers that sit between the user and the MCP client, and lightweight post-processing for localizing tool outputs. All patterns are demonstrated with working code from production voice agent systems built for Indian users.
With the MCP Dev Summit landing in Bengaluru, this is a timely and locally grounded conversation the ecosystem needs to have.
