Three small Cloudflare tools, now open source

These three utilities cover recurring Cloudflare tasks: request handling, Wrangler configuration review and release-file verification. The versioned downloads below include the source and instructions for each task.

Worker Request Kit

Five request helpers: bounded JSON, CORS, idempotency keys, honeypots and keyed identity hashing. No persistent deduplication, rate limiter or hosted service.

Cloudflare Workers Web APIs; Node.js 22.13+ for tests.

Wrangler Config Doctor

Catch eight common Wrangler configuration problems offline, from a CLI or local MCP client. Advisory checks, not full Wrangler validation. No account token or deployment.

Node.js 22.13+; Windows untested.

Cloudflare Release Proof

Create release manifests and verify that local folders or public HTTPS files contain the expected bytes. Point-in-time byte checks, not deployment ownership or hardened hosted SSRF protection.

Node.js 22.13+; Windows execution untested.

Package contents and operating limits

Each release includes a checksum and a working example. The two command-line tools also expose local, read-only MCP tools. Worker Request Kit is a library you import directly into a Worker.

These releases cover the jobs described above. They are not hosted services, complete Cloudflare account managers or claims of production readiness. Start with the included examples and tell us what gets in your way through the public repositories.

No sign-up or payment is required. Original code is MIT licensed; bundled dependency notices are included. Valen Systems is independent of Cloudflare.
