"A simple memory MCP server with read/write tools and vector database search" matching MCP servers:

Read-only security audit for Supabase. Surfaces RLS gaps, permissive policies, exposed functions and grants, and returns scored findings with fix SQL that is never executed.

Community MCP server for the Cymulate security validation platform. It exposes the full Cymulate REST API (337 endpoints) as 106 semantic tools for BAS, exposure validation, attack surface management, and platform administration.

Enables guardrail and trust testing by exposing realistic malicious tool patterns such as shell execution, credential dumping, and data exfiltration, all without network access.

Enables MCP clients to invoke common Kali Linux pentesting tools directly as tool calls, with each binary executed safely without a shell.

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

Enables security analysts to carry structured investigation state across sessions by storing typed observations, hypotheses, tasks, evidence and versioned decisions in a local SQLite graph with full-text search. It also enforces authorized scope and request controls, redacted and content-hashed evidence, duplicate-test signatures and validation gates that leave findings in draft until reproducibly confirmed, then produces technical and executive reports for Antigravity, Codex and other stdio MCP clients.

Enables Antigravity to act as an automated Cheat Engine/memory editor for singleplayer Windows games, providing process attachment, memory scanning/reading/writing, freezing, pointer and AOB resolution, Lua scripting, Cheat Table support, and stealth-oriented operations such as low-footprint syscalls and DLL injection.

Integrates 7 security tools (nmap, nuclei, dirsearch, sqlmap, hydra, Acunetix, Metasploit) via MCP protocol for AI-assisted penetration testing with enterprise-grade safety features.

Unified vulnerability search MCP server for penetration testing agents, integrating 5 data sources (NVD, OSV, EPSS, CISA KEV, Exploit-DB+GitHub) and 10 MCP tools for CVE query, keyword search, batch query, EPSS scoring, KEV checking, exploit search, and comprehensive assessment with Chinese output.

An MCP server that integrates various penetration testing tools, enabling security professionals to perform reconnaissance, vulnerability scanning, and API testing through natural language commands in compatible LLM clients like Claude Desktop.

An MCP server that integrates multiple security and reconnaissance tools (Nmap, Cariddi, ParamSpider, Metasploit, web scraping) for AI systems, enabling automated network scanning, API discovery, vulnerability testing, and remote access via ngrok.

Enables users to run synthetic support-agent evaluations, preserve and inspect traces, score results deterministically, inject failures, and enforce release review gates through MCP tools, resources, and prompts.

A production-ready HTTP API server for security testing and reconnaissance, integrating nmap, cariddi, paramspider, metasploit, and web scraping via FastAPI. It supports optional ngrok tunneling and exposes tools through REST endpoints.

Exposes a hardened Docker container with Kali Linux security tools (nmap, sqlmap, dig, whois, etc.) as MCP tools, enabling network reconnaissance, web analysis, and vulnerability scanning through natural language commands.

Enables querying a vulnerability database API to browse vendors and products, retrieve CVEs by ID, fetch the latest 30 CVEs with CAPEC/CWE/CPE expansions, and inspect database update status.

Enables users to query a vulnerability database for vendors, products, vulnerabilities by product, specific CVE IDs, recent CVEs with CAPEC/CWE/CPE expansions, and database update information.

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 users to browse vendors and products, retrieve vulnerabilities by CVE ID, fetch the latest CVEs with CAPEC/CWE/CPE expansions, and inspect database update information through the CVE-Search API.

Enables users to query the CVE-Search API to browse vendors and products, retrieve vulnerabilities by vendor and product, fetch specific CVE records, list recent CVEs with CAPEC/CWE/CPE expansions, and inspect database update status.

An MCP server for red teaming that enables AI agents to perform port scanning, vulnerability scanning, SSH operations, and Metasploit exploitation through a unified interface.
