MCP Zero-Touch Auth Stable; Fable 5 Free Window Closes July 19

MCP Enterprise-Managed Authorization graduates to stable, replacing per-server OAuth consent with zero-touch IdP SSO — now live across Anthropic, VS Code, Okta, and seven SaaS platforms including Asana, Figma, and Linear. Anthropic also extends Fable 5 free access through July 19 (its third reprieve) as a mystery Honeycomb EAP ...

Highlights

MCP's identity layer solidifies as Enterprise-Managed Authorization graduates to stable — and Anthropic's Fable 5 free window closes in four days.

Zero-touch IdP SSO replaces per-server OAuth consent across a growing roster of enterprise platforms, while a mysterious model surfaces in Cursor and the July 28 migration clock ticks to 13 days.

    MCP Enterprise-Managed Authorization Hits Stable

    EMA replaces per-server OAuth consent: orgs configure approved MCP servers once in their IdP, and users get zero-touch access on first login. Anthropic shipped EMA across its shared Claude MCP layer (Claude, Claude Code, Cowork); VS Code integrates it natively. Asana, Atlassian, Canva, Figma, Linear, and Supabase are live; Slack in progress. For enterprise teams stalled by unmanageable per-user consent flows, this is the unblocking event. (InfoQ)

    Fable 5 Extended to July 19; “Honeycomb EAP” Glimpsed in Cursor

    Anthropic pushed Fable 5’s subsidized window to July 19 11:59 PM PT — Pro, Max, Team, and premium Enterprise subscribers keep up to 50% of weekly limits at no extra cost (third reprieve since the June export-control pause). Separately, “Claude Honeycomb EAP” briefly appeared in Cursor’s model picker before being pulled; community analysis tied its spec to Fable 5’s architecture and theorized an Opus 5 early-access label. Anthropic has not confirmed; nothing appears in official API docs. (BleepingComputer, TechTimes)

    Microsoft Agent Framework 1.11.0 / 1.13.0: Progressive MCP Discovery Ships

    Python 1.11.0 introduces progressive MCP tool discovery — agents fetch tools incrementally across a session rather than enumerating all upfront, cutting startup latency for large registries. .NET 1.13.0 adds session isolation for Foundry Hosting, expanded skills APIs, and file editing tools. Both carry breaking changes; version-pinned production deployments need a migration review before upgrading. (GitHub)
