AI Identity

An AI agent can be aligned with its task when you hand it a token and drifting two minutes later. Here is how the alignment problem shows up in real agent workflows, and how to enforce alignment at runtime with a per-action authorization check.

Shared coding-agent memory over MCP improves velocity, but every retrieval is a delegated access decision. This guide explains runtime authorization, ReBAC modeling, inheritance boundaries, revocation, and audit design for secure team memory.

AI incident-response agents should not inherit remediation authority by default. This guide defines a practical trust-level taxonomy for MCP tool calls, shows where policy step-up approvals are required, and explains what enterprise audit trails must capture before any production mutation.

The fast-mcp-telegram and LiteLLM CVE chains show that authentication failures rapidly become unauthorized tool execution. The fix is fail-closed, runtime tool-call authorization at the MCP boundary.

MCP is making agentic ERP integration easier, but security now depends on runtime authorization at the tool-call layer. Learn how to model scoped permissions, trust levels, and audit evidence for finance, HR, procurement, and payroll workflows.

Specs and PRDs make coding agents more accurate, but not inherently safe. This guide explains how to secure MCP-enabled coding and workflow agents with short-lived delegated access, runtime policy decisions, and auditable zero standing permissions.

Subagents are delegated actors, not implementation details. This guide explains how to design MCP permission delegation, OAuth token brokering, approval routing, and audit trails to avoid silent stalls and privilege expansion.

Hermes Agent's Blank Slate direction shows why teams are moving from broad default tool access to zero standing permissions with config pinning and runtime authorization. This guide explains the safest local defaults, risk-tiered tool access, and practical temporary grant patterns for web, browser, terminal, MCP, memory, and delegation.

DIDs, verifiable credentials, and AI control towers are foundational for agent governance, but they still do not decide whether a specific agent action is allowed right now. This article explains the runtime authorization model enterprises need for delegated AI execution.

It had every permission it needed and a ticket telling it exactly what to do. Blocked once, it reworded the request to fool the check. Blocked again, it asked me to switch the check off. This is the call-by-call trace of why nothing left Linear, and the design decision that made "reword it until it's allowed" a dead end.

The LiteLLM CVE-2026-42271 and Starlette BadHost CVE-2026-48710 chain turned authenticated command injection into unauthenticated RCE. The deeper lesson: AI gateways hold model credentials, route sensitive traffic, and expose MCP utility endpoints — and need action-time authorization, not flat API keys.

Sandboxing a coding agent isolates it from the host—but the real blast radius is the credentials it holds. GitHub tokens, cloud keys, MCP connections, and CI/CD access define what an agent can actually do. Here's the runtime permission model that closes the gap.

Coding agents are operational actors, not just assistants. This guide presents a practical trust-level taxonomy for agent commands and MCP tools, explains why human approval prompts degrade at scale, and shows how runtime authorization policy enforces trust levels without relying on click fatigue.

Treating AI agents like service accounts is a useful starting point — but it fails at runtime. Here's why scoped tokens are necessary but not sufficient, and how runtime authorization fills the gap.

The Claude Code MCP OAuth token theft chain is an authorization failure, not just a credential leak. OAuth got the agent connected, but it never constrained which tool calls remained valid after the routing layer was tampered with — and that is the gap runtime policy enforcement must close.

The IETF SD Agent draft and Microsoft Entra Agent ID are turning agent identity into real infrastructure. But a verified Agent Card or sponsored enterprise identity still doesn't answer whether an agent may call a specific MCP tool right now — that requires runtime authorization.

Microsoft Entra Agent ID and SD-JWT agent identity solve registration, governance, and authentication, but they don't decide whether a specific MCP tool call is permissible right now. This article explains the gap and the runtime authorization architecture needed to close it.

In April 2026, the NSA published 'Careful Adoption of Agentic AI Services' — the first intelligence-community advisory specifically targeting AI agent authorization failures. Here is what it actually demands and why most engineering teams are not close to meeting it.

If you already run OPA, AI agents don't require a new policy engine — they require a richer input schema, ephemeral identity, and enforcement at every layer. Learn how to evolve your OPA setup for delegated, multi-hop agentic authorization with Zero Standing Permissions, production-grade Rego, and OPAL-backed real-time enforcement.

Zero standing privileges (ZSP): no identity holds access between tasks. How it differs from least privilege, how to enforce it, and why AI agents need it.

MCP OAuth 2.1 requires protected resource metadata, authorization server discovery, PKCE, and resource indicators. This guide walks through each spec requirement and shows where fine-grained authorization picks up after the OAuth flow ends.

AI agents acting on behalf of users need more than authentication — they need governance. This article covers the Permit.io agentic identity model, policy-as-code lifecycle, MCP Gateway enforcement, zero standing credentials, Guardian Agents, and what an audit trail must contain to be meaningful.

Coding agents execute code, run commands, and call APIs — not just generate text. This guide covers the real security risks, why authorization must happen at the tool-call level, and how Permit.io and the Permit MCP Gateway enforce least-privilege access for agentic workflows.

AI agents acting across tools, APIs, and multi-agent pipelines raise hard questions about identity, authentication, and authorization. This article covers agentic identity (delegating human + workflow context + intent), agent interrogation, SPIFFE, OAuth token exchange, least privilege at runtime, and what audit actually means for agentic systems.

AI agents break the traditional least-privilege model. This article explains why, defines agentic identity (delegating human + workflow context + declared intent), and shows how Permit.io enforces zero standing privileges through gateway-vaulted credentials, the PDP, MCP Gateway, and downscoped delegation chains.

RBAC is useful for coarse AI agent guardrails, but ReBAC is needed for delegated, tenant-aware, resource-level authorization. Learn when to use RBAC, ReBAC, and both for secure agentic systems.

MCP auth is necessary, but it is not the same thing as agent authorization. If you want secure agent systems, you need identity, delegation, policy, and runtime enforcement beyond OAuth.

An MCP proxy forwards traffic between MCP clients and servers. An MCP gateway adds identity, consent, authorization, and audit to every agent tool call.

Announcing Permit MCP Gateway, a new trust and enforcement layer for MCP that brings identity, consent, fine-grained authorization, auditability, and runtime control to AI agent actions.
