Cloudflare Workers¶

Workers are edge runtime services deployed on Cloudflare.

Upstream references¶

• Workers Documentation
• Workers Best Practices

What upstream owns¶

• Worker runtime behavior
• bindings
• compatibility dates
• deployment APIs

What VCQA owns¶

• compatibility-date policy.
• Worker-specific deployment and secrets checks.
• runtime anti-patterns.

Detection signals¶

• wrangler.toml, wrangler.json, or wrangler.jsonc
• Worker entrypoint source
• Cloudflare worker dependencies

Composed standards¶

• Cloudflare Worker MCP Server
• Tenant-Deployed Cloudflare SaaS

Combination-born guidelines¶

• Workers plus MCP requires protocol-safe request handling and authorization at the edge.
• Workers plus Durable Objects requires object ID scoping and storage migration discipline.
• Workers plus TypeScript requires avoiding Node-only APIs unless explicitly polyfilled.
