Reclaiming Your Agency: MCP, OAuth 2.1 and the Power to Automate Anything - BRKSEC-2065#

Cisco Live US 2026 (Las Vegas) digest Program Core pick Las Vegas · 31 May – 4 June 2026

Abstract

Jeremiah Williams (Cisco)

  • Why: Agentic identity is an emerging core interest, and this is the standards-level session — MCP authorization, OAuth 2.1, fine-grained authorization — rather than a product pitch.
  • What: How the emerging agentic-AI security stack works: Model Context Protocol (MCP), OAuth 2.1, fine-grained authorization, and related mechanisms for controlling what autonomous agents can access and do (from abstract only).
  • How: Explores how these standards combine to give agents delegated, scoped, auditable access to business applications — and notes the same machinery applies to human identity.
  • Where applicable: Standards-track and vendor-neutral (MCP, OAuth 2.1, fine-grained authz are IETF/OpenAI-ecosystem work); product agnosticism should be verified in the deck.
