# 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 CVEs, GHSA advisories, and patched versions for PyPI, npm, Go, or Rust 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-43ddc2ee
```

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

## When to prefer this

Choose this endpoint when you need live, up-to-date CVE and GHSA vulnerability data for open source packages across PyPI, npm, Go modules, or Rust crates — especially in CI/CD pipelines, dependency auditing workflows, or agent-driven security checks. It draws directly from Google OSV.dev, making it more comprehensive and fresher than static NVD snapshots.

## Known failure modes

- Package not found in OSV.dev returns empty advisory list or 404-style response
- Invalid ecosystem prefix causes a parsing or validation error
- Network timeout if OSV.dev upstream is slow or unavailable
- Ambiguous package name without ecosystem prefix may return incorrect results
- Rate limiting or payment failure (HTTP 402) if x402 micropayment 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/pypi-vuln-scan)

## Output

Returns a structured list of active CVEs and GHSA advisories affecting the queried package, including vulnerability IDs, severity ratings, affected version ranges, and the earliest patched version available, sourced live from Google OSV.dev.
