# 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 2026-10-28).

Queries Google OSV.dev for live CVE and GHSA vulnerability advisories on PyPI, npm, Go, or Rust crate packages and returns active vulnerabilities with patched versions.

## Facts

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-5386ad64 -d '<json body>'
```

Example prompt: Can you scan the PyPI package 'requests' for any active CVEs or GHSA security advisories and tell me which versions are patched?

## When to prefer this

Choose this endpoint when you need real-time, authoritative CVE and GHSA vulnerability data for open-source packages across PyPI, npm, Go modules, or Rust crates — especially when you want live OSV.dev data rather than a static database snapshot. Prefer this over generic vulnerability databases when you need both CVE and GHSA coverage in a single call with patched version recommendations.

## Known failure modes

- Unknown or misspelled package name returns empty vulnerability list or 404-style error
- Unsupported ecosystem prefix returns validation error
- OSV.dev upstream API downtime causes failed or stale response
- Malformed 'Ecosystem:name' format triggers input validation error
- Payment failure (HTTP 402) prevents query from executing

## 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/pypi-vuln-scan)

## Output

Returns a structured object containing active CVEs and GHSA advisory identifiers for the queried package, affected version ranges, severity information, and recommended patched versions sourced from live Google OSV.dev intelligence.
