Article Summary
The article outlines critical security considerations for building robust Model Context Protocol (MCP) servers, emphasizing the need for comprehensive protection against various threats.
- It highlights authentication as a foundational layer, discussing token-based methods like OAuth2 and JWT for verifying client identity.
- Authorization is crucial for controlling resource access, with the implementation of roles, permissions, and access control lists (ACLs) to manage what authenticated clients can do.
- Data integrity and confidentiality are addressed through encryption (e.g., AES) and hashing for data-at-rest and TLS/HTTPS for data-in-transit, protecting sensitive context information.
- Best practices include secure coding, regular security audits, managing secrets securely, and implementing rate limiting and input validation to mitigate common attack vectors.
