MCP Enterprise-Managed Authorization extension reaches stable

Category: Agentic coding
Status: confirmed
Sources: Model Context Protocol blog, discussion
Summary: The Model Context Protocol project marked its Enterprise-Managed Authorization (EMA) extension stable. EMA lets an organization centrally control which MCP servers employees may connect to through the corporate identity provider, replacing per-user, per-server OAuth prompts with a single sign-in governed by IdP policy. The post reports Anthropic implemented EMA in its shared MCP layer across Claude, Claude Code, and Cowork; VS Code added IDE support; and Asana, Atlassian, Canva, Figma, Granola, Linear, and Supabase support it, with Slack adding it.
Why it matters: Centralized IdP control over MCP server access removes a per-user authorization bottleneck and gives security teams a governance point for agent tool access in the enterprise.
Follow-up: Track which additional MCP servers and clients implement EMA and whether the extension stays stable through the next spec revision.
