Why it matters
AI agents need runtime access to credentials to act autonomously, making stolen tokens, leaked MCP config secrets, and unverified agent registration real attack surfaces defenders must lock down.
ZITADEL's explainer on AI agent impersonation walks through six ways an agent's identity can be exploited—credential theft, fake agent registration via OAuth Dynamic Client Registration, and others—and the mitigations that close each. It cites GitGuardian data on nearly 29 million hardcoded secrets and 24,008 unique secrets in MCP-related config files on public GitHub in 2025, and points to MCP's November 2025 authorization update favoring Client ID Metadata Documents over DCR.
