3.
Cloudflare opens Agents SDK to all frameworks, starting with Flue
Directly relevant to Fuzzy's MCP/agent work; opens a new deployment path for durable agents on Cloudflare.
Cloudflare opened the Agents SDK so any agent framework can build on its primitives; Flue is the first framework to target it, and agent management is now available in the dashboard.
⚠ Uncertainty: Flue is a new and unproven framework; actual ergonomics of the SDK are not yet clear from the blog post alone.
