# 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 in real time to return active CVEs, GHSA advisories, and patched versions for a given PyPI, npm, Go, or Rust 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-785a1ed4
```

Example prompt: Can you check if the PyPI package 'requests' has any known CVEs or GHSA security advisories right now, and tell me what patched version I should upgrade to?

## When to prefer this

Choose this endpoint when you need real-time, live CVE and GHSA vulnerability data for a specific open-source package across PyPI, npm, Go, or Rust ecosystems. It is backed directly by Google OSV.dev, making it more authoritative and up-to-date than static NVD snapshots or bundled security databases. Prefer it over generic web search for security advisories when you need structured, machine-readable vulnerability data with exact affected version ranges and patch recommendations.

## Known failure modes

- Package not found in any supported ecosystem — returns empty advisory list or error
- Malformed package identifier format — missing ecosystem prefix or invalid name
- OSV.dev upstream unavailability — request timeout or 5xx error
- Unsupported ecosystem queried — ecosystems outside PyPI, npm, Go, crates.io may return no results
- Payment not fulfilled — 402 response if x402 micropayment is not completed

## 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/vuln-scanner)

## Output

Returns a structured object listing all active CVEs, GHSA security advisories, affected version ranges, and recommended patched versions for the queried package from the live OSV.dev database.
