Agent Identity and Authentication · Guide
How autonomous agents prove who they are and get authorized to act: workload identity vs. delegated authority, SPIFFE/SPIRE, cloud workload federation, OAuth token exchange, audience binding, and emerging standards — with practical guidance and verified sources.
Agent Delegation Chains: Credential Propagation in Multi-Agent Systems · Reference
How credential authority flows when one agent spawns another — the multi-hop delegation problem, RFC 8693 token exchange, the act/may_act claims, audience binding across hops, and the IETF drafts standardizing verifiable actor chains in 2026.
Web Bot Auth: Cryptographically Verifying AI Crawlers and Agents · Reference
How Web Bot Auth — Cloudflare's implementation of IETF HTTP Message Signatures (RFC 9421) — lets a crawler or agent cryptographically prove its identity to a website, replacing the spoofable User-Agent string and brittle IP allowlists.
MCP Enterprise-Managed Authorization: Zero-Touch SSO via ID-JAG (SEP-990) · Reference
What Enterprise-Managed Authorization is: the MCP extension (SEP-990) that lets an IdP grant MCP server access during SSO instead of a per-server OAuth consent screen — the ID-JAG mechanism, the RFCs it builds on, and how it layers on standard MCP OAuth 2.1.

Guides

Agent Spend Limits and Trust: What a Seller Should Verify Before Granting Access · guide
The seller-side counterpart to agent spend controls — how an API operator reads an inbound agent's spend ceiling before granting access, which payment protocols actually prove that ceiling, how to revoke access, and what "trust" operationally means for a seller when no portable agent-reputation standard exists yet.
Fraud and Abuse from AI Agent Traffic: What a Seller Should Detect · guide
How a seller of APIs, content, or tools to AI agents spots and mitigates abuse once access is already granted — key sharing, over-scope scraping, spend-ceiling circumvention, spoofed identity, and rate-limit evasion patterns specific to autonomous agents.
Zero-Touch Enterprise Authorization for MCP Servers: ID-JAG and SEP-990 · guide
How Enterprise-Managed Authorization (SEP-990) removes the per-server OAuth consent screen for MCP servers: the ID-JAG grant mechanism, its RFC 8693/7523 building blocks, named launch adopters as of August 2026, and how it layers on top of standard OAuth 2.1 rather than replacing it.
