Deploy Cloudflare Workers as custom OAST endpoints for blind XSS payload hosting, configurable callback receivers, and SSRF redirect servers. Use when you need attacker-controlled infrastructure beyond what interactsh/webhook.site provides — custom response bodies, JS payload serving, or 302 redirect chains. Requires CLOUDFLARE_API_TOKEN and CLOUDFLARE_ACCOUNT_ID (CF_API_TOKEN / CF_ACCOUNT_ID aliases accepted). Triggers on 'blind XSS', 'custom callback server', 'OAST worker', 'serve a…
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
# Wrangler OAST — Cloudflare Workers for Out-of-Band Testing Deploy Cloudflare Workers as custom OAST (Out-of-Band Application Security Testing) endpoints. This complements interactsh and webhook.site by giving you **programmable** callback infrastructure at the edge. **Activation gate:** Only use this skill when `CLOUDFLARE_API_TOKEN` and `CLOUDFLARE_ACCOUNT_ID` are set in the environment (the `CF_API_TOKEN` / `CF_ACCOUNT_ID` aliases also work). If unset, do not suggest wrangler — fall back to `get_callback_url` (webhook.site / interactsh), which needs no credentials. Do not ask the user to enable it; state the requirement once if a technique genuinely needs a custom endpoint and move on. ## When to Use This vs. Interactsh | Need | Tool | |---|---| | Detect whether a target makes an outbound request | interactsh / `get_callback_url` | | Serve a **custom JavaScript payload** (blind XSS) | `wrangler_deploy` with `blind-xss` template | | Serve a **custom HTTP response** (content-type, headers, body) | `wrangler_deploy` with `custom` template | | **302 redirect** an SSRF to a different target | `wrangler_deploy` with `redirect` template | …

How to install
mdr add dreadnode/capabilities/wrangler-oast@sha256:c398481b84bc13ceThe line at the top of this page pins the label git:20260827.9e5b22d, 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.
