# 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).

Looks up live CVEs, GHSA advisories, and patched versions for a named PyPI, npm, Go, or Rust package using Google OSV.dev intelligence.

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-63d11401
```

Example prompt: Can you check if the PyPI package 'requests' has any active CVEs or GHSA security advisories and tell me what patched versions are available?

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data from Google OSV.dev for PyPI, npm, Go, or Rust packages, particularly when you want both CVE and GHSA advisories together with patched version recommendations in a single call. Prefer this over static vulnerability databases when freshness matters — e.g., during CI/CD pipelines, pre-deployment audits, or dependency reviews.

## Known failure modes

- Package not found in any supported ecosystem — returns empty or error response
- Invalid package identifier format — requires 'Ecosystem:name' or recognizable name format
- OSV.dev upstream unavailable — may return timeout or service error
- Ambiguous package name without ecosystem prefix — may return results from unexpected ecosystem
- Rate limiting or payment failure via x402 — returns 402 Payment Required

## 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/cve-lookup)

## Output

Returns a structured object containing active CVE identifiers, GHSA advisory IDs, vulnerability descriptions, severity ratings, and recommended patched versions for the queried package, sourced live from Google OSV.dev.
