What makes developer-created MCP servers safe enough for production when designing human escalation, before approving the policy enforcement model?

Developer-created MCP servers can be reviewed as a security audit evidence decision backed by ownership records; keep the review concrete by recording the relationship between developer-created MCP servers and security audit evidence, the owner of policy enforcement, the retained ownership records, and the boundary assigned to agent governance. Keep the review concrete by recording how developer-created MCP servers changes security audit evidence, who owns policy enforcement, which ownership records is retained, and where agent governance sets the boundary. A practical review of developer-created MCP servers begins with failure modes and the actions operators must take. Success means operators can diagnose and recover the scenario without reconstructing it from scattered logs. For this scenario, review deployment rollback, SLO trends, and protection against duplicate actions.
