Workers TCP sockets
Teaches how to use the connect() API to establish outbound TCP connections from Cloudflare Workers to support application-layer protocols like SSH, MQTT, or database wire protocols.
When To Use
Use when you need to implement outbound TCP connections for protocols such as SSH, SMTP, or direct database communication from a Worker environment.

What This Skill Covers
- The Workers runtime provides the connect() API for creating outbound TCP connections ↗ from Workers.
- Main sections:
connect(),SocketAddress,SocketOptions,SocketInfo,Socket.
Workflow
- Open the most relevant file under
docs/for the exact documented workflow and wording. - Open
schemas/files for exact structured contracts. - Open
examples/files for concrete requests, commands, snippets, and manifests. - Do not add behavior or configuration that is not present in the attached source files.
