Cloudflare API MCP server sends Workers Issues as MCP Events

The Cloudflare API MCP server now exposes Workers Issues as MCP Events through webhook subscriptions, allowing agents to receive real-time notifications when production failures are detected without polling. Clients can subscribe to cloudflare.alert.workers_observability_real_time_issue scoped to an account or individual Worker.

Workers Issues provides built-in error monitoring for Cloudflare Workers. It detects production failures and groups related failures into issues without an SDK or application wrapper.

The Cloudflare API MCP server now sends these issues as MCP Events ↗︎, the first event it exposes. MCP clients discover cloudflare.alert.workers_observability_real_time_issue with events/list and subscribe with events/subscribe, scoped to an account or a single Worker. When Issues detects a new or recurring issue, the server posts a signed event to the client's webhook, so an agent can start investigating without polling.

To use it, enable Issues on your Worker and connect https://mcp.cloudflare.com/mcp with the Notifications Write and Workers Observability Write permissions to a client that supports MCP Events webhooks.

Workers subrequests now preserve context for BYOIP destinations

Cloudflare Workers now preserves context when subrequests target BYOIP-proxied hostnames, maintaining CF-Worker headers and client signals. This ensures consistent security rule evaluation and accurate Bot Management results instead of incorrectly treating internal traffic as external.
