# 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 for live CVE and GHSA vulnerability advisories affecting a named PyPI, npm, Go, or Rust crate package, returning active vulnerabilities and patched versions.

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-fec1dbdb
```

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

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability intelligence from Google OSV.dev for open-source packages across PyPI, npm, Go modules, or Rust crates — especially when you need CVE and GHSA advisory data with patched version recommendations. Prefer over static NVD lookups when freshness matters or when scanning supply-chain dependencies during CI/CD pipelines or code reviews.

## Known failure modes

- Package not found in OSV.dev — returns empty advisory list or 404-style response
- Unsupported ecosystem prefix — malformed 'Ecosystem:name' input may yield no results
- No vulnerabilities found — clean package returns empty advisories array, not an error
- Rate limiting or upstream OSV.dev outage — service may return 5xx or timeout
- Payment required — HTTP 402 returned if x402 micropayment not included

## 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/epss-scanner)

## Output

Returns a structured list of active CVEs, GHSA advisories, affected version ranges, severity data, and available patched versions for the queried package, sourced live from Google OSV.dev.
