[gotcha] The MCP specification does not define security controls

Treat MCP as a transport protocol only. Build your own authentication, authorization, sandboxing, output sanitization, and audit layers, and use OWASP MCP Top 10 and SAFE-MCP as implementation baselines rather than assuming the protocol enforces them.

Journey Context:
New adopters often assume that because MCP is a standardized protocol, it includes normative security requirements. It does not: it standardizes message formats and capability negotiation, while leaving identity, isolation, and enforcement to implementations. This is by design for flexibility, but it means two MCP deployments can have wildly different security postures while being fully protocol-compliant. The practical takeaway is to stop asking 'is my MCP server compliant?' and start asking 'does my host enforce least privilege, origin authentication, and auditability across every server?'
