# 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 live vulnerability data for a given PyPI, npm, Go, or Rust package and returns active CVEs, GHSA advisories, 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-cc93f34f
```

Example prompt: Check OSV.dev for any active CVEs or GHSA advisories affecting PyPI:requests — I want to know if there are known vulnerabilities and what version has the fix.

## When to prefer this

Choose this endpoint when you need live, authoritative CVE and GHSA vulnerability data sourced directly from Google OSV.dev for PyPI, npm, Go, or Rust packages. It is ideal for CI/CD security gates, dependency audits before deployments, or any agent workflow that must verify the safety of open-source packages in real time. Prefer it over static databases or GitHub's API when you need cross-ecosystem coverage (Python, JavaScript, Go, Rust) in a single call with patched-version guidance.

## Known failure modes

- Package not found in OSV.dev — returns empty advisory list or 404-style error
- Malformed package identifier (e.g. wrong ecosystem prefix) — validation error returned
- OSV.dev upstream unavailable — service may return 503 or timeout
- Payment not completed (x402) — 402 response blocking access
- Rate limiting if too many calls in quick succession

## 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/ghsa-advisories)

## Output

Returns a structured list of vulnerability records for the queried package, including CVE IDs, GHSA advisory identifiers, severity ratings, affected version ranges, and recommended patched versions sourced live from Google OSV.dev.
