Audit MCPs for security vulnerabilities.
Scan My MCP is a specialized security auditing tool designed for MCP (Multi-Channel Platform) servers that deploy LLM agents with integrated tools and prompts. It automatically connects to any MCP server, thoroughly enumerating exposed endpoints, configurations, and permissions. The tool then conducts six critical security checks: secret exposure, authentication enforcement, dangerous permissions, input validation, prompt injection vulnerabilities, and context-window cost analysis. Every identified issue is accompanied by precise location details and recommended fixes, making it an invaluable resource for developers and security teams aiming to safeguard their MCP deployments. Its instant web interface and optional CLI integration cater to both quick scans and in-depth local audits, emphasizing ease of use and comprehensive security coverage.
Pros
- Automates comprehensive security assessments for MCP servers
- Provides detailed findings with actionable fixes
- Easy to use via instant web interface and CLI options
- Focuses on critical vulnerabilities like secret leaks and prompt injection
- Suitable for both remote and local MCP audits
Cons
- Limited information on pricing and licensing models
- May require technical expertise to interpret some findings
- Currently lacks integration with broader security platforms
Best for
- • Auditing MCP servers for security vulnerabilities before deployment
- • Regular security checks for ongoing MCP maintenance
- • Identifying secret leaks and permission issues in LLM-based tools
- • Ensuring input validation and prompt safety in AI workflows
Pricing: Likely employs a freemium model with a free web-based scan option; premium features or CLI tools for local and advanced scans may require subscription plans, though specific pricing details are not publicly available.
External security scan of your own IP, in your terminal
qsa.sh is a powerful command-line tool designed for developers and security professionals to perform quick, comprehensive external security scans of their own servers. With a single curl command, users can instantly see what the internet perceives about their server—covering open ports, service versions, and known vulnerabilities—delivered directly to their terminal within approximately 30 seconds. Its integration of tools like naabu, nmap, vulners, and nuclei ensures a detailed mapping of potential security gaps without requiring any accounts or data storage. The platform caters to both free, live scans and premium options like the Pro plan, which scans all 65,535 ports asynchronously, and a one-time Deep scan that digs deeper into hidden vulnerabilities via email. Its straightforward approach makes it ideal for sysadmins, security teams, and developers seeking a quick, transparent security overview of their infrastructure.
