Stealth Browser MCP Server

Automate web navigation past Cloudflare and anti-bot filters using real Chrome instances.

Data last scanned today · Reviewed today

Overview

Stealth Browser MCP Server provides AI agents with the ability to perform browser automation tasks that are typically blocked by anti-bot measures. By leveraging the nodriver library, Chrome DevTools Protocol, and FastMCP, it creates genuine Chrome-family browser instances to interact with websites that employ Cloudflare or other login walls. Designed for integration into MCP-compatible environments, this server allows your AI assistant to handle complex web navigation that standard scraping tools fail to execute. It serves as a bridge for agents needing to reach content protected by standard anti-bot software, maintaining stealth through its use of actual browser sessions.

Our verdict

With a security score of 50/100, this server is rated as high risk. Because it is a community-maintained project and has not yet undergone an editorial security review, users should exercise caution. Specifically, the authentication and read-only modes remain unreviewed, making it suitable primarily for development and testing environments rather than sensitive production workflows.

  • Supports navigation through Cloudflare and anti-bot challenges
  • Zero direct dependencies simplifies the supply-chain surface
  • Uses nodriver and Chrome DevTools Protocol for authentic browser sessions
  • Includes active development with commits within the last two weeks
  • High risk score due to lack of independent security review
  • Authentication methods have not been evaluated for safety
  • Community-maintained without official vendor support
  • Read-only mode implementation is currently unverified
