/ 100
Emerging

Defines 24 controls across 8 domains (filesystem, execution, network, authorization, input validation, logging, secrets, supply chain) mapped to risk-based compliance levels L1-L4, with deployment profiles for specific MCP scenarios and machine-readable JSON schemas for assessment reporting. The standard synthesizes NIST CSF, OWASP ASVS, and CIS Controls principles to address MCP-specific threats like command injection and supply chain compromise. Community-driven with i18n support, it targets the MCP ecosystem and integrates with platforms like MCP-Hub for standardized server certification.
