Agents, Workers - Cloudflare API MCP server sends Workers Issues as MCP Events

<p><a href="https://developers.cloudflare.com/workers/observability/issues/">Workers Issues</a> provides built-in error monitoring for Cloudflare Workers. It detects production failures and groups related failures into issues without an SDK or application wrapper.</p> <p>The <a href="https://developers.cloudflare.com/agents/model-context-protocol/cloudflare/servers-for-cloudflare/#cloudflare-api-mcp-server">Cloudflare API MCP server</a> now sends these issues as <a href="https://github.com/modelcontextprotocol/experimental-ext-triggers-events" target="_blank" rel="noopener">MCP Events<span class="external-link"> ↗︎</span></a>, the first event it exposes. MCP clients discover <code>cloudflare.alert.workers_observability_real_time_issue</code> with <code>events/list</code> and subscribe with <code>events/subscribe</code>, 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.</p> <p>To use it, <a href="https://developers.cloudflare.com/workers/observability/issues/#enable-issues">enable Issues</a> on your Worker and connect <code>https://mcp.cloudflare.com/mcp</code> with the Notifications Write and Workers Observability Write permissions to a client that supports MCP Events webhooks.</p>
