# 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-compiler.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Queries Google OSV.dev in real time to return active CVEs, GHSA advisories, and patched versions for PyPI, npm, Go, and Rust crate packages.

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-compiler-agentdiet-dev-real-time-open-source-package-cve-ghsa-d3568241
```

Example prompt: Can you check if the PyPI package 'requests' has any active CVEs or GHSA advisories right now, and tell me which versions have patches available?

## When to prefer this

Use this endpoint when you need real-time, live CVE and GHSA vulnerability data sourced directly from Google OSV.dev for PyPI, npm, Go modules, or Rust crates. Prefer it over static NVD lookups or periodic database snapshots when freshness matters — especially for CI/CD pipelines, pre-deployment audits, or security triage workflows that require up-to-date patched version information.

## Known failure modes

- Package not found in OSV.dev — returns empty advisory list or 404-style error
- Malformed package identifier (missing ecosystem prefix) — may return incorrect or no results
- OSV.dev upstream unavailable — returns service error or timeout
- No known vulnerabilities exist — returns empty result set (not an error)
- Rate limiting or payment failure ($0.01/call via x402) — returns 402 Payment Required

## 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-compiler.agentdiet.dev/v1/go-module-cve)

## Output

Returns a structured object containing active CVE identifiers, GHSA advisory IDs, affected version ranges, severity ratings, and the earliest patched versions for the queried package, sourced live from Google OSV.dev.
