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.

Quick Start

pip install git+https://github.com/zer0-kr/security-framework-mcp.git

Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "security": {
      "command": "security-framework-mcp"
    }
  }
}

Claude CLI (Claude Code):

claude mcp add security -- security-framework-mcp

<details> <summary>Other MCP clients (Cursor, OpenCode)</summary>

{ "security": { "command": "security-framework-mcp" } }

</details>

First run automatically builds the local database (~15-20 seconds). Auto-refreshes weekly.
