# 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 live vulnerability data for a named package and returns active CVEs, GHSA advisories, and patched versions for PyPI, npm, Go, or Rust ecosystems.

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-90d2003a
```

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

## When to prefer this

Choose this endpoint when you need live, up-to-date CVE and GHSA vulnerability data for a specific open-source package across PyPI, npm, Go, or Rust ecosystems. It is backed by Google OSV.dev for authoritative advisory coverage and is preferable to static NVD lookups when you want real-time patched version data alongside advisory metadata.

## Known failure modes

- Package not found in OSV.dev — returns empty or error response
- Invalid ecosystem prefix causes lookup failure
- OSV.dev upstream unavailable — service may time out or return error
- Malformed package identifier (missing colon separator) causes bad request
- No vulnerabilities found is a valid empty result, not an error

## 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/zero-day-advisories)

## Output

Returns a structured object containing active CVEs, GHSA advisory IDs, vulnerability descriptions, severity information, and the patched/safe versions available for the queried package, sourced live from Google OSV.dev.
