What happened
C1 (AI-native identity security platform) announced on June 18, 2026 day-one support for Enterprise-Managed Authorization (EMA), the open MCP standard for governing AI agent access to enterprise tools. As Anthropic shipped the first EMA implementation in Claude, C1 issues short-lived, scoped OAuth tokens across every compatible MCP server, authenticating users once through C1 while keeping every downstream agent action governed from a single control plane.
Why it matters
EMA addresses the primary security gap in MCP deployments: unmanaged, long-lived credentials that give agents excessive persistent access. C1's day-one support sets a practical reference for how enterprise identity platforms should integrate with the emerging MCP ecosystem.
Applicability
Enterprises deploying Claude agents or any MCP-connected agentic workflows should evaluate EMA-compatible identity platforms; security architects designing agent authorization models should treat EMA + scoped token issuance as the baseline.
