BrowserTools MCP implements the privacy-first principle at the design level:
Data storage mechanisms
- localization: All screenshots are saved by default to
/mcp-screenshotslocal catalog - memory limit: Data such as web logs are only retained at runtime and automatically cleared after service restart
- encrypted transmission: TLS encrypted communication between extensions and servers
Privacy by Design
- No background services: the entire system can run without an Internet connection
- Open source transparency: all code hosted on GitHub for review
- Privilege minimization: extensions request only the necessary activeTab and debugger permissions
Enterprise-grade security
- Passed OWASP Top 10 Security Audit
- Sensitive operations (e.g. screenshot autopaste) require secondary confirmation
- furnish
--inspectPatterns for security teams to verify data flow
