d-browser

d-browser is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from forever-healthy/AI4L. Its token cost is not measured, scanned A, original, MIT.

A tool connection that lets a coding agent use Playwright, a browser automation library, through a Docker container. The configuration runs it in headless mode, so no visible browser window is required.

In plain words
What is it for?
Use it when configuring an agent that needs browser automation through the Playwright MCP server.
Why use it?
It provides a packaged browser environment for automated web tasks instead of requiring a local browser setup. The input does not specify which browser actions are exposed.

Security

Grade A, and why

d-browser scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
