SMCP Proxy is a reverse proxy designed for Model Context Protocol (MCP) services, providing a security layer with OIDC authentication, supporting enterprise - level authentication and authorization, and simplifying standardized interactions with large language models (LLMs).

A service toolset based on the Model Context Protocol, providing functions such as encoding conversion, network diagnosis, system monitoring, security encryption, and QR code generation, and supporting LLM agents to call system tools.

GUARDRAIL is a security framework specifically designed for the large language model (LLM) application ecosystem, providing comprehensive protection especially for the Model Context Protocol (MCP). It uses a multi - layer architecture, including an information gateway layer, a context verification layer, a request control layer, an execution isolation layer, and an audit monitoring layer, aiming to prevent data leakage, unauthorized access, and resource abuse. This framework emphasizes progressive adoption, allowing developers to gradually enhance security while maintaining high performance and ease of use.

MCP Bridge is a lightweight, LLM-independent RESTful proxy for connecting to multiple Model Context Protocol (MCP) servers and exposing their functions through a unified REST API. It solves the problem that platforms such as edge devices, mobile devices, and web browsers cannot efficiently run MCP servers, and provides optional risk-based execution levels, including security controls such as standard execution, confirmation workflows, and Docker isolation.

MCP Guardian is a tool for managing LLM assistant access to MCP servers, providing real-time control, message logging, approval, and automated security check functions.

An open - source production - grade MCP server for integrating Wazuh security data with LLMs (such as Claude Desktop App).

A production - grade open - source MCP server for integrating Wazuh security data with LLMs (such as the Claude desktop application). This service authenticates through the Wazuh RESTful API, retrieves alerts from the Elasticsearch index, converts events into an MCP - compatible JSON format, and exposes an HTTP endpoint for the Claude desktop to obtain real - time security context.

The urlDNA MCP Server is a service that provides native tool usage for security-oriented LLM agents (such as OpenAI GPT-4.1 and Claude 3 Desktop), interacting directly with the urlDNA threat intelligence platform through the API. It supports various tools, including URL scanning, searching, and quick checking, and can be accessed via the SSE protocol.

sec-mcp is a Python security detection toolkit that provides security check functions for domains, URLs, IPs, etc. It supports integration with Python applications, use in the terminal CLI, or running as an MCP server to provide real-time threat insights for LLMs.

An MCP server integrated with MongoDB, designed specifically for recording and analyzing LLM security challenges, supporting AI security testing in the Grey Swan Arena competition.

A lightweight MCP server that supports the Garak LLM vulnerability scanning tool, providing functions such as listing model types, models, and attack probes, and can run attack tests to generate reports.

The MCP command server is a secure system command execution service that is invoked through LLM applications (such as Claude) and provides security features such as whitelist control, user confirmation, and audit logs.

MySSL MCP Server is a website security detection tool developed by TrustAsia, which supports integration with LLM models for certificate security checking.
