# 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-42b0195e
```

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 been patched?

## When to prefer this

Choose this endpoint when you need real-time, live CVE and GHSA vulnerability data for open-source packages in PyPI, npm, Go, or Rust ecosystems, especially when building automated security pipelines, CI gates, or dependency auditing agents. It is preferable over static NVD snapshots when freshness matters or when querying Rust crates.io packages specifically.

## Known failure modes

- Package not found in any supported ecosystem returns empty or null advisory list
- Malformed package identifier (missing ecosystem prefix or typo) may return no results or an error
- OSV.dev upstream unavailability could cause timeouts or degraded responses
- Packages in unsupported ecosystems (e.g. Maven, NuGet) may not return results
- Payment failure (HTTP 402) if x402 micropayment is not properly handled

## 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/cargo-vuln-scan)

## Output

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