# 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 live Google OSV.dev to return active CVEs, GHSA advisories, and patched versions for PyPI, npm, Go, or Rust crate packages.

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-b8ae0d5e
```

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

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data from Google OSV.dev for packages across PyPI, npm, Go modules, or Rust crates. Prefer it over static NVD database lookups when you need up-to-date CVE and GHSA advisory coverage, including the most recently patched versions. Ideal for CI/CD security gates, dependency auditing workflows, or agent-driven supply chain risk assessment.

## Known failure modes

- Unknown or misspelled package name returns empty results or error
- Unsupported ecosystem returns validation error
- Network timeout if OSV.dev upstream is slow or unavailable
- Malformed package identifier format causes bad request error
- Package with no known vulnerabilities returns empty advisory list (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/vuln-scanner)

## Output

Returns a structured object listing all active CVEs and GHSA advisories found for the queried package, including severity ratings, affected version ranges, and the patched versions that resolve each vulnerability, sourced live from Google OSV.dev.
