Instead of hosting your own AgentWelcome.md and redeploying on every change, a Hosted ECP Context Server gives you a single URL to drop into your site configuration, with support for on-demand updates, live data, API integrations, and more.
When an agent hits your canonical URL, ECP routes it to a context server that returns structured, current information about your site. Your products, services, status, API surface. Browsers continue to get your existing HTML. Same URL, two audiences, served correctly.
A context server can be as simple as an AgentWelcome.md file you write once and update in a browser, or as dynamic as a live-updating cache that reflects your actual operational state. The provider you choose determines what is possible.
Get started with our ECP.dev Context Server, free for anyone to use. Write and update your AgentWelcome.md directly in the browser. Cloudflare-backed global delivery. Your content is always updatable with no redeploys and no code changes.
Specialized ECP Context Servers with richer analytics, CMS integrations, team workflows, or vertical-specific context formats are expected to emerge as the ecosystem matures. Providers are encouraged to get in touch.
If you're building an ECP-compatible context server, we'd like to know. The criteria are straightforward: your server must deliver a valid non-HTML response to agent callers at the canonical URL, return the correct Vary headers, and be publicly reachable.
