Description
MCP Defender is an innovative open-source desktop application that serves as an AI firewall, specifically designed to oversee and safeguard communications related to the Model Context Protocol (MCP). By functioning as a secure proxy between AI applications and MCP servers, it meticulously analyzes all communications in real-time to detect potential threats. This application automatically scans and secures all MCP tool calls, leveraging advanced LLM capabilities to identify malicious activities effectively. Users have the flexibility to manage the signatures utilized during the scanning process, enabling tailored security measures that fit their specific needs. MCP Defender excels in recognizing and preventing a range of AI security threats, such as prompt injection, credential theft, arbitrary code execution, and remote command injection. It seamlessly integrates with numerous AI applications, including Cursor, Claude, Visual Studio Code, and Windsurf, with plans for expanded compatibility in the future. The application provides intelligent threat detection and promptly alerts users as soon as it detects any malicious actions perpetrated by AI applications, ensuring a robust defense against evolving threats. Ultimately, MCP Defender empowers users with enhanced security and peace of mind in their AI interactions.
Description
Workplace use of AI tools such as ChatGPT, Copilot, Claude, Perplexity and DeepSeek has surged, often without oversight from IT departments. More than 92% of employees now use generative AI at work, exposing financial data, API keys, passwords, source code and personal records. Traditional Data Loss Prevention (DLP) solutions and proxies were not built for this new threat. Enter ZeusLock, a DLP solution designed specifically for the AI era. It analyzes prompts, files and images in real time and detects, anonymizes or blocks sensitive data before it reaches any AI service. Deployment takes about two minutes through a browser extension and an endpoint agent for Windows, macOS and Linux, protecting web apps, desktop apps, IDEs, terminals and AI agents, including their connections through the Model Context Protocol (MCP). Each data type is set to Off, Alert or Block per policy; Alert mode can anonymize values while preserving their format, and every incident is logged in masked form for auditing. ZeusLock also stops prompt injection and jailbreak attacks, and its Shadow AI Discovery maps the AI tools employees actually use, with risk scores and approval status. Detection relies on a dedicated multimodal language model backed by deterministic rules, hosted in Europe, or fully on-premise with the Sovereign Edition, with no US cloud dependency. This approach lets organizations embrace AI tools with confidence while keeping their data secure.
