Proposes a four-layer defense-in-depth architecture for securing Model Context Protocol (MCP) in production, moving beyond simple gateway authentication. The framework addresses critical vulnerabilities like SSRF and schema drift by enforcing controls across secure tool execution, isolated management planes, restricted outbound trust, and semantic integrity via manifest pinning.

Securing MCP in Production: A Four-Layer Defense-in-Depth Architecture Beyond Gateways
Original: 在生产环境中保护MCP：超越网关的纵深防御
- MCP security requires a layered approach covering execution, infrastructure management, outbound trust, and semantic integrity; gateways cannot replace semantic layer protection.
- Vulnerabilities like CVE-2026-26118 demonstrate that inbound authentication alone is insufficient; outbound egress controls and scoped tokens are necessary to mitigate SSRF risks.
- Pin tool manifests at registration to prevent 'rug-pull' behavior and embed diff-based reviews into CI pipelines as an operational model.
