Repository Install

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

概要

AI coding agents recommend and install packages without knowing if they're safe — and most security tools require accounts, API keys, or paid plans to tell you. Hound fixes that: it scans for vulnerabilities, checks licenses, audits dependency trees, and detects typosquatting across 7 ecosystems — zero config, zero API keys, zero cost. Hound is the only security tool built specifically for AI coding agents — works across npm, PyPI, Go, Cargo, Maven, NuGet, and RubyGems, and plugs into Claude Code, Cursor, VS Code, and any MCP client out of the box. It uses two fully free, unauthenticated public APIs: (Google Open Source Insights) and (Google Open Source Vulnerabilities). 12 tools → Full reference with example outputs npm · pypi · go · maven · cargo · nuget · rubygems 3 prompts you can invoke directly from your AI client.

Why Hound?

AI coding agents recommend and install packages without knowing if they’re safe — and most security tools require accounts, API keys, or paid plans to tell you. Hound fixes that: it scans for vulnerabilities, checks licenses, audits dependency trees, and detects typosquatting across 7 ecosystems — zero config, zero API keys, zero cost.

Hound is the only security tool built specifically for AI coding agents — works across npm, PyPI, Go, Cargo, Maven, NuGet, and RubyGems, and plugs into Claude Code, Cursor, VS Code, and any MCP client out of the box.

It uses two fully free, unauthenticated public APIs: deps.dev (Google Open Source Insights) and OSV (Google Open Source Vulnerabilities).
