security-framework-mcp
Provides comprehensive access to OWASP security frameworks, including Top 10, ASVS, WSTG, Cheat Sheets, and more, enabling security analysis, compliance mapping, and vulnerability management.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@security-framework-mcpfind recent critical CVEs"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
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.gitClaude Desktop (claude_desktop_config.json):
{
"mcpServers": {
"security": {
"command": "security-framework-mcp"
}
}
}Claude CLI (Claude Code):
claude mcp add security -- security-framework-mcp{ "security": { "command": "security-framework-mcp" } }First run automatically builds the local database (~15-20 seconds). Auto-refreshes weekly.
