browser-server

browser-server is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from blacklanternsecurity/red-run. Its token cost is not measured, scanned A, original, GPL-3.0.

A local browser-control service configured for the red-run security project. It lets the coding agent use browser-related tools through MCP, a standard way for applications to expose tools to an AI assistant.

In plain words
What is it for?
Running browser-related operations locally for red-run engagements.
Why use it?
It provides the project with its configured browser tooling without requiring a remote browser service.

MCP server for Claude CodeCodexCursorGemini CLIOpenCode

Written for no agent in particular: it speaks MCP, so any client can run it. Also seen: listed in a Claude config.

One of 7 entries in .mcp.json upstream. Installing this one merges just its entry into your config; the other 6 are separate, each on its own page.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Security

Grade A, and why

browser-server 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 1mo 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.
