Unified MCP server integrating NIST and OWASP security frameworks with live vulnerability data, enabling security searches, compliance mapping, threat modeling, and checklist generation.
Unified NIST + OWASP security framework MCP server
Search and query 4,700+ security data points through a single MCP interface — NIST (1,196 SP 800-53 controls with 53A assessments and 53B baselines, CSF 2.0, PF 1.0, SP 800-37 RMF, 613 publications, CMVP, NICE, glossary, CSF↔800-53 mappings) and OWASP (Top 10, API/LLM/MCP Top 10, ASVS 5.0, WSTG, MASVS, Proactive Controls, 815+ CWEs, 559 CAPEC attack patterns, 113+ Cheat Sheets, 418+ projects) — with live NVD/CVE + CISA KEV + EPSS, PDF reading, compliance mapping, STRIDE threat modeling, and MCP security assessment.
