Enables users to retrieve and display CVE vulnerability information from the National Vulnerability Database (NVD) with support for keyword search and detailed lookup.

Enables AI assistants and agents to search bug bounty programs, retrieve policies and scopes, and check targets against active scope across HackerOne, YesWeHack, and Intigriti using personal API credentials.

AI-powered penetration testing reasoning engine (MCP server) for attack path planning, step scoring, and tool recommendations using Beam Search and Monte Carlo Tree Search.

Enables AI agents to interact with the FlagForge REST API, allowing them to search solved CTF challenges, work on live event challenges, record evidence, submit flag candidates, and write markdown writeups.

Provides AI assistants with secure access to Metasploit Framework functionality through a standardized interface, enabling commands, exploit search, module info, and scanning.

An AI-powered penetration testing reasoning engine that provides automated attack path planning, step-by-step guidance for CTFs/HTB challenges, and tool recommendations using Beam Search and MCTS algorithms.

Enables AI agents to look up files, URLs, IPs, and domains through the VirusTotal v3 API, returning detection reports alongside analyst-pivot relationships such as contacted hosts, dropped files, resolutions, and threat actors. Adds corpus search, sandbox behaviour summaries, cursor-paginated relationship traversal, and a choice of stdio or HTTP streaming transport.

Enables AI agents to query the VirusTotal v3 API for detection reports and analyst-style pivots on files, URLs, IPs, and domains, including contacted hosts, dropped files, resolutions, and threat actors. Provides relationship paging, corpus search with VTI-style modifiers, sandbox behaviour summaries, and supports both stdio and HTTP streaming transports.

An MCP server providing 15 OSINT tools over free, public sources for AI agents, enabling domain reconnaissance, subdomain discovery, DNS lookups, host profiling, CVE search, and more without API keys.

Enables AI agents to perform internet reconnaissance, device search, DNS lookups, and CVE/CPE vulnerability analysis through read-only Shodan-powered tools.

Enables querying CVE vulnerability data from the NIST National Vulnerability Database, including CVE lookup, product/version search via CPE filters, CVSS severity scores, and recent high-severity disclosures.

Enables certificate transparency log search via crt.sh, allowing users to query SSL/TLS certificates, enumerate subdomains, and retrieve certificate details with no API key required.

Gives AI agents access to the VirusTotal v3 API so they can look up hashes, URLs, IPs, and domains and receive detection reports with relationship pivots like contacted hosts, dropped files, and threat actors.
