A malicious package named postmark-mcp on npm, which allowed AI assistants to send emails, was discovered to have a hidden line of code that forwarded all outgoing emails to a stranger. This incident highlighted the critical need for continuous verification of software dependencies, as trust established at installation can decay over time. The solution proposed involves capturing and continuously comparing concrete, structural descriptions of tools and APIs, rather than relying on initial trust assessments. Meanwhile, the Model Context Protocol (MCP) has evolved its authentication mechanisms, moving from self-issued credentials to a standardized OAuth 2.1 flow where MCP servers act as resource servers validating tokens issued by separate authorization servers. This shift addresses enterprise needs for centralized access management, policy enforcement, and instant revocation, moving beyond individual user consent flows. AI
