About

MCP Defender is an open source desktop application that functions as an AI firewall, designed to monitor and protect Model Context Protocol (MCP) communications. It acts as a secure proxy between AI applications and MCP servers, analyzing all communications for potential threats in real-time. It automatically scans and protects all MCP tool calls, providing advanced LLM-powered detection of malicious activity. Users can manage the signatures used during scanning, allowing for customizable security measures. MCP Defender identifies and blocks common AI security threats, including prompt injection, credential theft, arbitrary code execution, and remote command injection. It supports integration with various AI applications such as Cursor, Claude, Visual Studio Code, and Windsurf, with more applications to be supported in the future. It offers intelligent threat detection, alerting users as soon as it identifies any malicious activity being performed by AI apps.

About

AI tools like ChatGPT, Copilot, Claude, and DeepSeek are widely used at work - often without IT oversight. Up to 78% of employees admit using ChatGPT professionally, risking exposure of financial data, API keys, passwords, source code, and personal records. Legacy DLP and proxies weren't built for this threat. ZeusLock is the purpose-built DLP for the AI era. It automatically detects and blocks sensitive data before it reaches any AI service. Deployment takes 2 minutes via a browser extension and workstation agent, covering web apps, IDEs, terminals, and AI agents via MCP. When a risk is detected, ZeusLock either alerts the user or blocks the submission - based on your policy - and logs every incident for a full audit trail. It also guards against Prompt Injection, Jailbreak attacks, and unauthorized shadow AI tools like DeepSeek. Detection runs locally, with an ML API hosted in Europe for full data sovereignty. Zero latency, zero productivity impact.

Audience

AI developers and security-conscious organizations seeking a solution to safeguard their AI applications against advanced threats by monitoring and protecting MCP communications in real-time

Audience

Any organization where employees use generative AI tools (ChatGPT, Copilot, Claude…) in their daily workflows. Primary targets include mid-size to large enterprises in regulated industries - finance, healthcare, legal, and HR - where data confidentiality and GDPR compliance are critical. Also ideal for tech companies handling sensitive source code and API credentials, as well as CISOs, IT security teams, and compliance officers seeking visibility and control over shadow AI usage across their workforce.
