wrangler-oast skillC

wrangler-oast is agent-read markdown (skill) from dreadnode/capabilities: 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 payload', .

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add dreadnode/capabilities/wrangler-oast@git:20260827.9e5b22d
Exact content
mdr add dreadnode/capabilities/wrangler-oast@sha256:c398481b84bc13ce

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
