Agents, Workers - Cloudflare MCP servers support the new MCP 2026-07-28 Specification
Cloudflare's product-specific MCP servers now support the new MCP 2026-07-28 Specification. Each request runs on a fresh stateless server without an MCP protocol session or protocol-specific Durable Object. The /mcp endpoint also accepts stateless requests from 2025 Streamable HTTP clients.

Browser Run adds structured handoff for Human in the Loop
Browser Run now supports structured handoff for Human in the Loop workflows. Using Cloudflare-specific CDP commands , your agent can signal that it needs help, a human steps in through Live View to handle the task, and the agent resumes once the work is done.
Cloudflare One, Gateway - Control Cloudflare Gateway DNS caching with a maximum TTL setting
You can now set a maximum time-to-live (TTL) for DNS responses returned by Gateway. When an upstream DNS record has a TTL that exceeds the configured maximum, Gateway caps it to your specified value. This ensures that DNS policy changes - such as blocking a newly identified malicious domain - take effect faster across all clients.
Workers AI - Select models now require the Workers Paid plan
We are limiting Workers Free plan access to a few resource-intensive models so we can prioritize capacity for the broader Workers AI user base. This helps everyone get a more reliable inference experience, with fewer 429 and 3040 (Out of Capacity) errors.
Workers tracing , write custom spans with new startActiveSpan() and span.end() runtime APIs
The Workers runtime now provides built-in tracing.startActiveSpan() and span.end() APIs, allowing you to write custom spans for operations that last beyond a single callback , for example, instrumenting a stream pipeline where the span should stay open until the stream is fully consumed.
