# 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 in real time to return active CVEs, GHSA advisories, and patched versions for PyPI, npm, Go, or 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-security-agentdiet-dev-real-time-open-source-package-cve-ghsa-3107f2a1
```

Example prompt: Can you check if the npm package lodash has any active CVEs or GHSA advisories, and tell me which version has the fixes?

## When to prefer this

Choose this endpoint when you need real-time, authoritative CVE and GHSA vulnerability data for PyPI, npm, Go, or Rust crate packages sourced directly from Google OSV.dev. It is ideal for pre-deployment security checks, CI/CD dependency auditing, and supply chain risk assessment where up-to-date advisory data matters more than static snapshots.

## Known failure modes

- Unknown or misspelled package name returns empty or not-found result
- Missing ecosystem prefix may cause ambiguous or incorrect package resolution
- Package exists in multiple ecosystems and wrong one is queried
- OSV.dev upstream API unavailability causes timeout or error
- Payment failure (HTTP 402) blocks the request if x402 payment is not completed

## 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/maven-vuln-scanner)

## Output

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