About
Endpoint Context Protocol (ECP) is a lightweight method for making any existing website agent-friendly by leveraging standard HTTP content negotiation headers. With a few lines of code, the same URL can return human-readable HTML to browsers and clean semantic content to AI agents and LLMs — no new infrastructure or routing required. It also offers an optional hosted context server and a public directory for agent-discoverable site listings.
Problem
AI agents and LLMs cannot easily extract structured, authoritative information from websites designed for human browsers.
For
web developers and site owners who want their existing sites to be accessible to AI agents and LLMs
How it works
By inspecting HTTP request headers (Sec-Fetch-Dest and Accept), the server detects whether the caller is a browser or an agent and returns either standard HTML or a clean semantic payload from the same canonical URL.
