Why it matters
Excessive agency in AI agents connected to MCP servers gives them far more authority than intended, so defenders need per-operation scoping to prevent an invoice-reading agent from also releasing payments.
LangGuard's article explains least-privilege permission scoping for AI agents, arguing that agents inherit the full action surface of every MCP tool they connect to and must be scoped per operation rather than per system. It maps OWASP LLM06:2025 Excessive Agency's three causes (excessive functionality, permissions, and autonomy) onto scoping decisions and describes its SCOPE-MCP feature that enumerates and classifies operations against segregation-of-duties rules.
