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

​
Project Goals

Secure Transport

Secure communication channels for MCP

Authentication

Authentication mechanisms for MCP servers/clients

Authorization

Fine-grained access control for MCP operations

Audit Logging

Security audit trails for MCP interactions

​
Key Features (Planned)

  • TLS/SSL support for MCP transports
  • Certificate validation and management
  • Secure WebSocket connections
  • API key authentication
  • OAuth2/OIDC integration
  • Role-based access control (RBAC)
  • Policy-based authorization
  • Schema validation for MCP requests
  • Parameter sanitization
  • Protection against injection attacks
  • Request rate limiting
  • Resource usage quotas
  • DDoS protection
  • Security event logging
  • Audit trail generation
  • Compliance reporting

​
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:
Security Risks:
  • Unauthorized access to sensitive resources
  • Data exfiltration through MCP tools
  • Code injection via malicious prompts
  • Resource exhaustion attacks
  • Privilege escalation
MCP Security aims to provide a comprehensive security framework to mitigate these risks.

​
Use Cases

1

Enterprise MCP Servers

Secure MCP servers for enterprise environments with strict security requirements
2

Multi-tenant Systems

Isolate MCP resources and operations across different tenants
3

Public MCP Services

Protect public-facing MCP endpoints from abuse and attacks
4

Regulated Industries

Meet compliance requirements for healthcare, finance, and government sectors

​
Getting Started

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