Building MCP Before MCP Existed: Inside Despegar's Sofia Agent
MLOps.community
Origins: combining human-agent know-how with LLMs
Nicolas describes how Despegar leveraged human agent expertise to identify valid Sophia use cases and iteratorially build features.
Nicolas Alejandro Bogliolo is the AI PM at Despegar, the largest online travel agency in Latin America, and the engineer-product-hybrid behind Sofia, the GenAI travel concierge that beat most of the OTA world to a working multi-agent system.
Before MCP was a standard and before LangChain was widely adopted, his team had already shipped their own orchestration layer and tool protocol in production. This conversation is a rare look at what it takes to build an agentic system that actually books trips, runs on WhatsApp, and keeps adding capabilities without falling over.
