"Library for performing depth-first search to find paths under a domain" matching MCP servers:

Enables domain overviews for security and sales, providing registration, infrastructure, and risk signal data through a simple API request.

Provides comprehensive email deliverability and domain registration analysis, evaluating SPF, DKIM, DMARC, DNS records, and expiry to identify issues and suggest fixes.

MCP server enabling Claude Code to capture screenshots of Windows applications through WSL2, allowing AI to diagnose UI errors and verify layouts.

MCP server providing comprehensive domain intelligence (WHOIS, DNS, SSL, domain age) for due diligence and security audits, with pay-per-call via x402 micropayments.

Enables AI agents to run domain-intelligence investigations through six free tools: sanctions screening, IP geolocation with VPN/Tor detection, email validation with breach status, company profiling, WHOIS and email-security scoring, and a single-call domain dossier.

MCP server that lets agents check domain email authentication (SPF, DKIM, DMARC, MX) via a free API, returning grades and shareable report URLs. Also provides tools for listing paid services and partner program terms.

Enables agents to call typed code-review and content-moderation decision tools, returning structured verdicts, probabilities, and confidence-gated actions.

Enables AI agents to audit email and domain security (SPF, DKIM, DMARC, etc.) for any domain without requiring API keys.

Enables AI agents to request an independent second opinion from a different frontier model, with PII scrubbing before transit, live web search grounding, caching, and multi-provider failover.

This MCP server provides secure access to databases for AI agents, enforcing authentication, authorization, human approval, logging, and notifications to prevent dangerous actions.

Enables auditing any domain's email deliverability and DNS health, including SPF, DKIM, DMARC, MX, mail provider, DNS blacklist status, catch-all, domain age, and a deliverability score.

Enables AI agents to run domain and website intelligence checks, including WHOIS/RDAP, DNS and email security, TLS headers, subdomains, tech stack, contacts, SEO, Core Web Vitals, sitemaps, and Wayback page diffs, using the caller's own Apify token.

Enables email and domain checks, including SPF lookup limits, DKIM keys, DMARC, DNS records, and registration expiry.

Two-way Burp Suite MCP bridge enabling AI agents to capture traffic, analyze endpoints, queue scans, and send findings back to Burp.

Provides AI assistants with specialized tools to interact with NIST's Open Security Controls Assessment Language (OSCAL) framework. It enables agents to retrieve schemas, explore models, and generate valid OSCAL documentation for security compliance automation.

Enables searching and analyzing CVEs and vulnerabilities from multiple sources, optimized for PR review scenarios to help developers identify the latest security issues.

Enables comprehensive threat analysis for Indicators of Compromise (IoCs) including IP addresses, file hashes, domains, and URLs. It provides detailed reputation scores, security vendor evaluations, and network metadata to facilitate security assessments and risk detection.

An MCP server that sends plain-text Gmail messages only to a predefined allowlist, using generated recipient IDs instead of email addresses to enforce security.

A client-side MCP proxy that injects OAuth 2.0 bearer tokens or API keys into MCP requests, enabling MCP clients to connect to OAuth/API-key-protected MCP servers like Amazon Bedrock AgentCore Gateway. It automatically fetches and refreshes credentials using AgentCore Identity or static values.

MCP server for AI search crawler governance, brand safety, and search infrastructure auditing. Provides tools to audit robots.txt, canonical links, sitemaps, redirects, and send IndexNow notifications.
