An MCP server configuration for Stagehand, a tool that lets an agent interact with web browsers. The configuration starts its server through Node.js.

Use it to configure Stagehand in an MCP-compatible agent setup. It helps start the server from the compiled JavaScript entry point.

It tells the agent how to launch the Stagehand service so browser-related requests can be connected to it. The supplied information does not describe the server’s specific browser actions.

Security

Grade A, and why

stagehand 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 yesterday.

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.
