# Prox

> Prox is the AI product specialist for manufacturers of complex physical products. It grounds answers in a company's own manuals and catalogs, cites them to the page, and deploys everywhere customers, dealers, and field technicians already work — including a hosted Model Context Protocol (MCP) connector for ChatGPT, Claude, Copilot, and Gemini. Backed by Y Combinator (F25), Bloomberg Beta, and investors from OpenAI and Microsoft.

This llms.txt was generated by the API Evangelist enrichment pipeline from the Prox APIs.json profile and captured artifacts. Prox is delivered primarily as an MCP connector; it does not publish a REST OpenAPI.
