PUMA Stage 5 Smart PMO uses MCP for tool integration (Jira API, GitHub). Understanding MCP security is important for the governance layer design.
PUMA Connection
PUMA’s governance layer (OPA policies, bounded autonomy — Constitution Article 4) must address MCP security threats. This paper provides the threat taxonomy for the ethics review (Section 1.3) and architecture spec.
