"How to look up websites using a search engine without APIs" matching MCP servers:

A personal work twin for any AI agent. It briefs agents on the guidance you have confirmed, checks consequential actions against explicit, expiring grants and asks otherwise, and turns your corrections into lessons only you can confirm.

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

Enables AI agents to call tools through a security gateway that intercepts requests, enforces deterministic policy and risk checks, blocks or escalates high-risk actions for human approval, and keeps tool credentials and audit logs protected.

Enables AI agents to safely operate on PostgreSQL data through typed MCP tools with per-identity RBAC, guardrails, and immutable audit logging.

Audits AI agent skills for safety using static, semantic, adversarial, and supply-chain analysis, providing scores and risk flags. Can be run via CLI, CI, or as an MCP tool from Claude Code, Cursor, and Codex.

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.

MEOK Governance Engine - MCP server providing AI-powered tools and automation by MEOK AI Labs

Enables generating falsifiable fleet hypotheses, compiling them into minimal bounded probe plans with control cohorts, and evaluating observations to return supported, refuted, or inconclusive verdicts.

Safety middleware for AI computer use agents that monitors, enforces policies, and provides guardrails to enable safe desktop interaction.

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.

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.

Enables permission-checked search of past chat history that links older messages with the latest activity, returning supporting context such as timestamps, speakers, and surrounding conversation. Authorization is re-verified against current room membership and approved groups on every search, message fetch, and period read.

A Model Context Protocol (MCP) server for accessing the CIRCL CVE SEARCH API, providing comprehensive vulnerability and security information.

Indexes a workspace and exposes code-navigation tools to Codex, enabling symbol lookup, reference finding, dependency analysis, and security audit for local codebases.

Enables checking IP reputations and threat intelligence by querying Chaitin's global honeypot network and millions of defense nodes. Provides real-time IP profiling, malicious behavior detection, and threat alerts based on aggregated security data.

Autonomous M2M compliance and trust APIs for AI agents (KYB, OFAC, VAT, Sanctions checking).

Provides agent certification and trust verification tools for AI agents, enabling certification checks, trust score calculations, audit ticket issuance, and emergency kill switch activation through the A-SOC trust network.

Enables querying the CVE-Search API to browse vendors and their products, retrieve vulnerabilities for a vendor/product pair, look up individual CVE IDs, and fetch the latest 30 CVEs with CAPEC, CWE and CPE expansions. It also reports which databases are in use and when they were last updated.

Enables querying the CVE-Search API to browse vendors and their products, retrieve vulnerabilities per vendor/product, look up specific CVE IDs, fetch the latest 30 CVEs with CAPEC, CWE and CPE expansions, and check database metadata. This gives MCP clients conversational access to public vulnerability data.

Enables SSL/TLS certificate search and analysis using crt.sh data, supporting domain certificate discovery, subdomain enumeration, and security auditing through Cloudflare Workers deployment.

Enables querying the CVE-Search API to browse vendors and their products, look up vulnerabilities by vendor/product or CVE ID, and retrieve the latest CVEs with CAPEC, CWE, and CPE expansions. It also reports which databases are in use and when they were last updated.

A secure MCP proxy server with JWT authentication, SQL guardrails, rate limiting, and Kafka audit logging, enabling enterprise-grade access control for MCP clients like Cursor and Claude Desktop.

Enables AI agents to manage VPN infrastructure through provisioning, lifecycle control, traffic routing, and health monitoring.

Enables users to browse vendors and products, retrieve vulnerabilities for a vendor/product, look up individual CVE IDs, fetch the latest CVEs with CAPEC, CWE, and CPE expansions, and check current database information through the CVE-Search API.

Provides live CVE data from NVD and EPSS without API key, enabling AI assistants to look up CVSS scores, search vulnerabilities, and check product CVEs.

Enables MCP clients to triage SOC alerts while enforcing a trust firewall across retrieval, memory, and privileged actions. It exposes tools for alerts, logs, memory, and alert actions, with defenses that refuse risky operations in the presence of attacker-controllable content.

Enables AI assistants to look up CVE details, EPSS exploit probability, and CISA KEV status from free public APIs to prioritize vulnerabilities by real-world risk. Combines these sources into a single enriched, prioritized view using a KEV > EPSS > CVSS rule.
