Guides, tutorials, and deep dives on MCP gateway security, AI agent permissions, and building safer agentic systems.
AI Agent Least Privilege: The Complete MCP Security Checklist [2026]
The principle of least privilege — giving each system only the minimum access it needs — is one of the oldest rules in security. AI agents violate it by default: they receive broad OAuth scopes, share credential pools, and have no per-agent permission boundaries. This guide explains why least privilege is harder for AI agents than for traditional software, provides a 10-point implementation checklist for MCP-based systems, and shows how to enforce it without rebuilding your infrastructure from scratch.
MCP Gateway: The Complete Guide [2026]
An MCP gateway sits between AI agents and external services, enforcing authentication, granular permissions, rate limiting, and audit logging on every tool call. With 97M+ MCP SDK downloads and 88% of organizations reporting AI agent security incidents, deploying an MCP gateway is no longer optional -- it is table stakes for production AI systems.
Docker MCP Gateway: Setup, Security & Best Practices
Docker MCP Gateway is an open-source project that lets you run MCP servers inside Docker containers, providing process isolation and a catalog-based discovery system for AI agents. It simplifies setup but does not solve permission-level security -- for granular per-agent scope control, you need a dedicated MCP proxy like ScopeGate on top.
