# Real-Time Open-Source Package CVE & GHSA Vulnerability Scanner (OSV.dev)

> Real-Time Open-Source Package CVE & GHSA Vulnerability Scanner (OSV.dev) is a paid API for AI agents from mcp-security.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Queries Google OSV.dev to return active CVEs, GHSA advisories, and patched versions for any PyPI, npm, Go, or Rust crate package.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability mcp-security-agentdiet-dev-real-time-open-source-package-cve-ghsa-3241ac36
```

Example prompt: Can you check if the PyPI package 'requests' has any active CVEs or GHSA security advisories right now, and tell me what patched version I should upgrade to?

## When to prefer this

Choose this endpoint when you need real-time, authoritative vulnerability intelligence for open-source packages across PyPI, npm, Go modules, or Rust crates, especially when you want CVE and GHSA advisory data directly from Google OSV.dev without maintaining your own vulnerability database. Prefer this over GitHub Dependabot alerts or Snyk when you need a lightweight, per-package on-demand lookup that returns structured advisory data for any ecosystem in a single call.

## Known failure modes

- Package not found in OSV.dev — returns empty advisory list or 404-equivalent
- Invalid ecosystem prefix causes query failure — requires correct format like 'PyPI:name' or 'npm:name'
- OSV.dev upstream unavailable — service may return timeout or 503
- Package name typo returns no results without error signal
- Rate limiting or payment failure returns 402 response

## How this service works

Queries live Google OSV.dev vulnerability intelligence for any PyPI, npm, Go, or Rust crate and returns active CVEs, GHSA advisories, and patched versions. (Live x402 v2, IETF MPP & MCP endpoint at https://mcp-security.agentdiet.dev/v1/vuln-scanner)

## Output

Returns a structured object listing all active CVEs and GHSA advisories for the queried package, including vulnerability identifiers, severity ratings, affected version ranges, and recommended patched versions sourced live from Google OSV.dev.
