Use when working on Cloudflare's edge platform — wrangler.jsonc bindings, choosing between D1/KV/R2/Durable Objects/Queues, deploying a Worker or SPA via Static Assets, or designing around a Workers runtime limit. NOT generic CI/release (that is `deployment`), NOT Next.js framework wiring (that is `nextjs`), NOT DNS records (that is `domains-dns`).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Cloudflare Workers & edge primitives ## The model in one paragraph A Worker is a `fetch` handler that runs at the edge. Everything else — R2, D1, KV, Queues, static assets, Durable Objects — is a **binding** declared in `wrangler.jsonc` and reached through `env`. If a resource is not bound, it is not reachable from your code. There is no connection string and no `import` of the bucket; you wire it in config, type it on `Env`, and call `env.BINDING`. Hold this picture and most "how do I access X" questions answer themselves: declare the binding, redeploy, use `env`. ## Quick start `npm create cloudflare@latest` (the C3 scaffolder) bootstraps a Worker or a full framework. Use it — it pins a correct `compatibility_date` and generates types. ```bash npm create cloudflare@latest my-app # plain Worker npm create cloudflare@latest my-app -- --framework=react # Vite + React SPA, GA plugin cd my-app npx wrangler dev # local edge emulation at http://localhost:8787 npx wrangler deploy # ships Worker + bound assets in one operation ``` Wrangler is **v4** (an incremental release over the v3 rewrite — same config model, updated deps). Pin it: `npx wrangler@4`. …

How to install
mdr add ericrisco/rsc-harness/cloudflare@sha256:935c9b50eeef2972The line at the top of this page pins the label git:20260729.3ecb845, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
