"SST" matching MCP servers:

Enables checking SSL certificate expiry for any domain, with status indicators for validity and remaining days.

Connects to Ubuntu servers over SSH to manage, maintain, and secure them through natural language conversation.

Implements a Model Context Protocol server using Server-Sent Events for real-time communication with OAuth 2.1 integration via Ory Network, enabling secure AI model communication with authentication and client management.

Enables AI-assisted penetration testing by connecting MCP clients to a Windows API server for executing penetration testing tools like nmap, ffuf, nuclei, and other security tools. Allows AI agents to perform automated security assessments, solve CTF challenges, and assist with ethical hacking tasks through natural language commands.

Enables live TLS/SSL certificate health checks for any hostname, providing expiry, hostname match, trust verdict, and a health score. Supports both free and paid deep tiers with protocol/cipher analysis.

Integrates 15+ static application security testing tools (Semgrep, Bandit, TruffleHog, etc.) with Claude Code AI, enabling automated vulnerability scanning and security analysis through natural language commands. Supports cross-platform operation with remote execution on dedicated security VMs.

Enables AI agents to check SSL/TLS certificate validity, expiry, issuer, chain details, and security grade for any domain via pay-per-call x402 micropayments.

This is a secure SSH MCP server providing enterprise-grade SSH management with AI assistance, MFA, RBAC, encryption, and compliance auditing.

Provides Azure Entra ID authenticated access to organizational development resources including checklists, process documentation, and workflows with dual-mode authentication support.

An MCP server that gives Claude a shell on your servers, and cannot use it without your explicit consent.

Enables AI assistants to securely execute shell commands on local machines through an SSH interface with session management, command execution, and sudo support.

Enables interaction with the Huntress SAT API to manage security awareness training, including learners, phishing campaigns, and training assignments. It supports OAuth2 authentication and optional role-based access control for secure organizational management.

Enables AI agents to validate SSL/TLS certificates, monitor expiration, verify certificate chains, assess security posture, and receive A-F security grades, with micropayment-protected access via x402.

Enables AI agents to securely access encrypted secrets (SSH keys, API tokens, passwords) with real-time user approval via Passkey, and supports SSH remote execution through the MCP protocol.

Provides prompt injection detection, PII/secrets redaction, and an audit trail for AI agents via MCP tools.

Enables secure remote SSH command execution with strict read-only enforcement, allowing safe delegation of SSH access to Claude while preventing write operations. Supports connection pooling, command validation, and comprehensive logging for audit trails.

Enables AI agents to scan code for security vulnerabilities using multiple static analysis tools, with support for filtering, deduplication, and CI/CD integration.

Manage AWS, Hetzner, OVH, and custom SSH servers from AI agents — commands, logs, CloudWatch/CloudTrail, IP banning, and S3, with guard tiers and a full audit trail.

Provides policy-driven, auditable SSH access to server fleets for AI assistants with zero-trust security controls, command whitelisting, and comprehensive audit logging to safely manage infrastructure.

Enables monitoring of domain registration information via WHOIS lookup and SSL certificate validity checking. Provides domain expiration dates, registrar details, certificate validity periods, and issuer information for website security monitoring.
