The MCP 2026-07-28 spec hardened authentication and routing, but OAuth alone still cannot decide whether a specific tool call should run. This guide explains the authn-vs-authz split and shows how to enforce runtime policy on tools/call.

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.

Coding agents can generate OpenAPI specs faster than most governance programs can review them. This article explains how to connect design-time API governance to runtime MCP tool authorization with policy decisions, constrained credentials, and audit receipts.

LLMs can draft authorization policy, but safe policy authoring for AI agents still depends on explicit intent, verifier-guided synthesis, and runtime PDP decisions on real tool calls.

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.

Cloudflare's x402 and paid MCP tooling make agentic payments real, but payment proof is not runtime permission. This guide explains spend authorization, consent tiers, and audit requirements for paid tool calls.

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.

MCP risk is not frozen at build time. This article explains how to vet third-party MCP servers, treat manifests as security boundaries, enforce runtime authorization, and preserve incident-grade audit evidence.

CVE-2026-49257 in mcp-pinot shows why network-reachable MCP database servers must fail closed: secure startup, endpoint authentication, and per-tool runtime authorization are all mandatory. This guide breaks down the confused-deputy pattern, risk-tiered tool policy for read vs schema/admin operations, and the audit model needed for real incident forensics.

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.
