What are common vulnerabilities in MCP systems?

Model Context Protocol systems face a many common vulnerabilities related to MCP security, a especially around handling, transmission and validation of contextual metadata. A key risk is context data tampering, where attackers intercept or alter data, it causing a incorrect model behavior or the exploitation. A weak authentication and authorization controls expose context data to unauthorized access, increasing a chances of data poisoning or leakage. Insufficient input validation can lead to injection attacks or processing malformed data, causing crashes or unpredictable AI outcomes. Insecure communication channels without encryption also make MCP systems vulnerable to monitor and man-in-the-middle attacks. A weak Inspectability and monitoring delay breach detection, prolonging risks. Additionally, the versioning or compatibility issues in MCP implementations can create semantic mismatches and resulting in security gaps. To address such things, organizations often depend on a trusted MCP security solution provided by an experienced MCP security vendor like Akto.io, offering encryption, runtime protection, and continuous monitoring.
