Pangea MCP Proxy: Secure Your MCP Servers From Malicious Entities and Confidential Data

The Pangea MCP Proxy is designed to safeguard any existing MCP (Model Context Protocol) server, ensuring secure communication by integrating it with the Pangea AI Guard service. This proxy helps protect against malicious inputs and outputs, making sure sensitive data like IP addresses and personal information are not compromised.

Overview: What is Pangea MCP Proxy?

The Pangea MCP Proxy acts as an additional layer of security for MCP servers. By leveraging the capabilities of Pangea AI Guard, it monitors and filters incoming and outgoing traffic, ensuring that only safe content passes through. This enhances the overall integrity and privacy of your applications by preventing unauthorized access to sensitive data.

🔧 Core Features & MCP Capabilities

The core features of the Pangea MCP Proxy include:

• Real-time Monitoring: Continuously analyzes and filters requests based on predefined rules and policies.
• Integration with Pangea Vault: Dynamically fetches necessary API tokens stored in Pangea Vault, ensuring secure and efficient execution of tasks.
• Customizable Policies: Allows administrators to define specific security measures for different types of content.

⚙️ MCP Architecture & Protocol Implementation

The architecture of the Pangea MCP Proxy is designed to seamlessly integrate with existing MCP servers while maintaining strict control over their interactions. The protocol implementation involves several key components:

1. MCP Client: Acts as a bridge between the AI application and the Pangea MCP Server, handling initial communication and data exchange.
2. Pangea MCP Server: Processes and filters input/output based on security policies before allowing it to proceed through the standard MCP protocol.
3. Data Source/Tool Integration: Facilitates secure interaction with various datasets and tools, ensuring that only approved content is utilized.

🚀 Getting Started with Installation

To use the Pangea MCP Proxy, follow these steps:

1. Prerequisites:

   • Node.js v22.15.0 or greater.
   • A Pangea API token for AI Guard and Vault.
   • Ensure both tokens are stored securely.

2. Configuration: Modify your existing MCP server configuration to include the proxy command and necessary environment variables:
