# 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-compiler.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Queries Google OSV.dev to return active CVEs, GHSA advisories, and patched versions for a given PyPI, npm, Go, or Rust crate package.

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-compiler-agentdiet-dev-real-time-open-source-package-cve-ghsa-d208f5ec
```

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

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability intelligence from Google OSV.dev for PyPI, npm, Go, or Rust crate packages specifically. Prefer it over static databases when you need up-to-date CVE and GHSA data with patched version information. Ideal for CI/CD pipeline security gates, pre-deployment audits, or agent-driven dependency reviews where freshness of advisory data is critical.

## Known failure modes

- Package not found in OSV.dev — returns empty vulnerability list or 404-style response
- Malformed package identifier (missing ecosystem prefix) may return incorrect or no results
- OSV.dev upstream unavailability may cause timeout or degraded response
- Package exists but has no known vulnerabilities — returns clean/empty advisory list
- Ecosystem not supported (e.g. Maven, NuGet) — may return error or empty result

## 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-compiler.agentdiet.dev/v1/npm-vuln-scan)

## Output

Returns a structured response containing active CVE identifiers, GHSA advisory references, affected version ranges, severity information, and the earliest patched versions available for the queried package, sourced live from Google OSV.dev.
