# 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 for live CVE and GHSA vulnerability advisories on a named PyPI, npm, Go, or Rust crate package and returns patched versions.

## 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-e1b6499a
```

Example prompt: Can you check if the npm package lodash has any known CVEs or GHSA security advisories right now, and tell me which versions are patched?

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability intelligence from Google OSV.dev for PyPI, npm, Go, or Rust crate packages — especially when you need CVE and GHSA advisory data with patched version guidance in a single call without maintaining your own vulnerability database.

## Known failure modes

- Package not found in OSV.dev — returns empty or null vulnerability list
- Invalid ecosystem prefix causes query failure or misrouted lookup
- OSV.dev upstream unavailable — service returns error or timeout
- Package name typo results in no matches
- Rate limiting or payment failure returns 402 error

## 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/maven-vuln-scanner)

## Output

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