Production-grade MCP server giving Claude 27 security intelligence tools across 21 APIs — CVE lookup, EPSS scoring, CISA KEV, MITRE ATT&CK, Shodan, VirusTotal, and more.

A free and open vulnerabilities database and the packages they impact. And the tools to aggregate and correlate these vulnerabilities. Sponsored by NLnet https://nlnet.nl/project/vulnerabilitydatabase/ for https://www.aboutcode.org/ Chat at https://gitter.im/aboutcode-org/vulnerablecode Docs at https://vulnerablecode.readthedocs.org/

🛡️ Free open-source AI-powered security terminal & vulnerability scanner (CVE, SBOM). Supports SSH, SFTP, RDP, VNC, Serial, and 12+ autonomous AI agents (DeepSeek, OpenAI) for automated security workflows, CTF & DevSecOps. Cross-platform & Web UI.

python dependency vulnerability scanner, written in Rust.

Is your lockfile pwned? 5-second scan of npm/PyPI/Maven/Cargo/Go/RubyGems lockfiles for compromised packages — OSV + curated campaign feed, --min-age cooling-off gate, exit 4 when a scan is incomplete. SLSA L3, Sigstore-signed feed.

☠️ Ground-truth dataset for vulnerability prediction (known research datasets and data sources included such as NVD, CVE Details and OSV); tools to automatically update the data are provided.

Parse and compare package versions and ranges. From debian, npm, pypi, ruby and more. Process all the version range specs and expressions. This project is sponsored by an NLnet project https://nlnet.nl/project/vulnerabilitydatabase/ , the Google Summer of Code, nexB and others generous sponsors!

Measure what a vulnerability is worth to your business, not how severe it is in the abstract. Business Exposure Index scoring over NVD, EPSS, CISA KEV, OSV and GHSA.

Turn an Erlang/OTP application into a Unikernel image

Artifacts, including experiments and graphs, for the paper: "Unikraft: Fast, Specialized Unikernels the Easy Way" (EuroSys'21 - Best Paper Award).

23-tool MCP server for CVE & vulnerability intelligence. NVD, EPSS, CISA KEV, GitHub Advisory, OSV — unified in one server. Risk scoring, bulk triage, exploit search. 2 dependencies, runs with npx.

AI security agent for the Python supply chain: scans packages, generates exploits, and validates them in Docker, autonomously.

🛡️ Blazing fast Supply Chain Security tool written in Rust. Features ephemeral sandboxing, hybrid analysis (CVE + Heuristics), and entropy-based malware detection.

A collection of packages for using security advisories from osv.dev in Node.js.

Vulnerability scanning with your own scanners and threat feeds, plus a coding agent that opens the fix PR. CLI, GitHub Action, or scheduled Managed Agents deployment.

Dependency safety gate for Claude Code & Codex CLI — OSV pre-approval, npm lockfile-closure enforcement, and auto-rollback. Local, zero runtime deps.

Capstan, a tool for packaging and running your application on OSv.

The dependency bloodhound for AI coding agents. Free, no API keys.
