dsh-cloudflare-browser-run

A DeepSeek Harness plugin that gives the agent real browser access: headless Chrome on Cloudflare's network, so JS-rendered pages, screenshots, and PDFs all just work.

Port of pi-cloudflare-browser-run, built to the dsh (Cordis) plugin spec.

Why

The built-in web_fetch is a plain HTTP fetch — JS pages come back empty and SSRF protection is deferred upstream. This plugin adds a real browser:

• clean markdown from any public page (SPA/JS included)
• screenshots (PNG) and PDFs
• login-capable sessions and WebMCP sites

Quick start

dsh plugin --profile web add dsh-cloudflare-browser-run

Configure credentials in your profile/settings layer:

- id: cloudflare-browser-run
  name: dsh-cloudflare-browser-run
  config:
    cf_api_token: <your token>
    cf_account_id: <your account id>

Token: Cloudflare dashboard → API Tokens → Browser Rendering: Edit template. Account id: dash.cloudflare.com/<ACCOUNT_ID>/....

Tools

Config

Privacy

• Public web only: every URL passes an SSRF guard (localhost / private IPs / IPv6 literals / userinfo rejected) before the API is called.
• The token lives only in your config file — never logged, never stored by the plugin.
• Browser Run identifies itself as a well-behaved bot, the compliant way to fetch.

Development

npm install
npm run typecheck
npm test          # SSRF guard / config / API shape
npm run build

Live API test (not part of npm test):

DSH_TEST_CF_TOKEN=<token> DSH_TEST_CF_ACCOUNT=<account> node --import tsx tests/real/real-cf.mjs
