Audit, Harden & Defend Your
Model Context Protocol Servers
AI agents in Claude, Cursor, and Zed execute commands with dangerous permissions. Scan for prompt injection, arbitrary bash execution, path traversal, and secret leaks in seconds.
Live Interactive MCP Security Scanner
Paste a tool definition, system prompt, or `mcpServers` config to run an immediate security audit.
The OWASP MCP Top 10 Threat Model
Model Context Protocol servers operate with autonomous agency. A single prompt injection in web content or email can trick the agent into executing catastrophic actions.
Arbitrary Command Execution
Tools running bash or shell interpreters without strict allowlisting allow attackers to inject malicious shell operators.
Path Traversal & System Reads
Unsandboxed filesystem tools let agents traverse outside working directories (`../../etc/shadow` or `.env` files).
Credential Exposure in Configs
API keys, bearer tokens, and DB connection strings hardcoded inside `claude_desktop_config.json` without env vaults.
Indirect Prompt Injection
Hostile content in webpages or emails overrides model system instructions and instructs the agent to misuse tools.
Destructive Excessive Agency
High-impact actions (DROP database, delete file, execute transaction) executed without explicit user confirmation.
Tool Output Secret Reflection
Tools echoing internal API tokens, passwords, or PII into the LLM conversation context, resulting in data exfiltration.
