# MCP Security

> Security support for Model Context Protocol implementations

<img src="https://img.shields.io/badge/Status-Incubating-blue" alt="Incubating Status" />

## Overview

The MCP Security project provides security support and best practices for implementing secure Model Context Protocol (MCP) servers and clients in Java.

<Note>
  This is an incubating project focused on bringing enterprise-grade security to MCP implementations.
</Note>

## Project Goals

<CardGroup cols={2}>
  <Card title="Secure Transport" icon="lock">
    Secure communication channels for MCP
  </Card>

  <Card title="Authentication" icon="key">
    Authentication mechanisms for MCP servers/clients
  </Card>

  <Card title="Authorization" icon="shield-halved">
    Fine-grained access control for MCP operations
  </Card>

  <Card title="Audit Logging" icon="file-shield">
    Security audit trails for MCP interactions
  </Card>
</CardGroup>

  </Accordion>
</AccordionGroup>

## Why MCP Security Matters

The Model Context Protocol enables powerful integrations between AI systems and external tools/resources. However, this power requires careful security considerations:

<Warning>
  **Security Risks:**

  * Unauthorized access to sensitive resources
  * Data exfiltration through MCP tools
  * Code injection via malicious prompts
  * Resource exhaustion attacks
  * Privilege escalation
</Warning>

MCP Security aims to provide a comprehensive security framework to mitigate these risks.

## Use Cases

<Steps>
  <Step title="Enterprise MCP Servers">
    Secure MCP servers for enterprise environments with strict security requirements
  </Step>

  <Step title="Multi-tenant Systems">
    Isolate MCP resources and operations across different tenants
  </Step>

  <Step title="Public MCP Services">
    Protect public-facing MCP endpoints from abuse and attacks
  </Step>

  <Step title="Regulated Industries">
    Meet compliance requirements for healthcare, finance, and government sectors
  </Step>
</Steps>

## Getting Started

<Info>
  This project is currently in the incubation phase. Documentation and examples will be added as features are implemented.
