Enables AI agents to run reconnaissance tasks such as DNS, WHOIS, certificate transparency, TLS certificate, HTTP header, and limited port checks against explicitly authorized domains and IPs. Scope permissions, deny rules, default-deny resolution pinning, rate budgets, and append-only audit logging are all enforced inside the server so an out-of-scope request cannot be expressed.

Exposes an OSINT investigation toolkit to any MCP-compatible AI client, which can drive passive checks such as DNS, WHOIS/RDAP, breach, IP reputation, GitHub and news-geo lookups and chain findings across them. The server lists 20 tools by default (16 passive plus 4 graph and batch helpers) and 25 when active checks are explicitly allowed, running via uvx with no separate install.

MCP server that exposes 31 OSINT checks from Lissy93/web-check as tools for website analysis, including SSL, DNS, headers, WHOIS, and security presets. Enables natural-language-driven web recon and health checks.

Enables AI assistants to perform domain reconnaissance using theHarvester OSINT tool, including email harvesting, subdomain discovery, DNS brute force, and Shodan integration, via SSH on a Kali Linux host.

A comprehensive MCP server for web security reconnaissance, providing tools for passive and active information gathering, DNS analysis, network scanning, and web application analysis.

A Model Context Protocol (MCP) server for interacting with the DNSDumpster API, enabling AI assistants to perform detailed DNS reconnaissance through natural language requests.

Enables out-of-band interaction testing by integrating ProjectDiscovery's interactsh service as an MCP server. Allows AI agents to create callback domains, send probes, and capture DNS/HTTP interactions for security testing and verification workflows.

MLNops is a local-first MCP server for authorized infrastructure reconnaissance and security posture analysis. It provides DNS, WHOIS, SSL/TLS, subdomain, ASN, cloud exposure, and full-recon tools for MCP clients.

Wraps the recon CLIs security researchers already use (subfinder, httpx, nmap, ffuf, nuclei) into a single MCP server so an LLM agent can plan and execute reconnaissance itself — passive subdomain/DNS/wayback discovery, active port scanning, WAF detection and origin-bypass checks, endpoint fuzzing, and nuclei scans. Structured JSON results carry scan tokens that let the agent chain one step's output into the next without re-typing targets.

Enables network scanning and reconnaissance tasks like port scanning, OS detection, DNS brute force, and more through MCP interfaces.

Provides a security proxy that sits between MCP clients and servers to inspect and filter traffic. Guards MCP sessions against leaked secrets, vulnerable dependencies, misconfigured DNS/TLS, and non-compliant data exposure.

Provides MCP clients like Claude with tools to query and manage security scans, CVEs, assets, findings, threat intel, and generate polished reports by acting as a lightweight adapter over the CVEasy backend API.

Enables unified security workflows with secret scanning, dependency CVE auditing, TLS/SSL inspection, and DNS/SPF/DMARC checks through a single MCP server.

Passive external attack-surface mapping server that discovers subdomains, DNS records, TLS posture, HTTP headers, and registration data via public sources like CT logs, Shodan, and RDAP/WHOIS, enabling security reconnaissance without active scanning.

It also delivers CVE/CPE vulnerability intelligence, including CVSS scores, EPSS estimates, and KEV status.

Enables AI agents to query the Shodan API and CVEDB for internet-connected device reconnaissance, returning open ports, banners, TLS certificates, cloud and location details, plus DNS records and subdomains.
