What is AgentAudit?

AgentAudit is an open security registry for AI agent packages (MCP servers, skills, npm/pip packages). It provides:

• Multi-model security audits (Claude, GPT-4o, Gemini, etc.)
• Consensus-based trust scoring
• Standardized vulnerability IDs (ASF-IDs)

The badge auto-updates as new audits are submitted. Full audit details: https://agentaudit.dev/packages/mcp-server-browserbase
