# 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-f0a5d4a2
```

Example prompt: Can you check if the PyPI package 'requests' has any active CVEs or GHSA advisories right now, and tell me which versions have patches available?

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data from OSV.dev for open-source packages across PyPI, npm, Go, or Rust ecosystems, especially when you want CVE and GHSA advisory details with patched version information in a single call. Prefer this over static NVD lookups or local databases when freshness matters.

## Known failure modes

- Package not found in OSV.dev — returns empty or error if ecosystem/name is invalid
- Unsupported ecosystem specified — only PyPI, npm, Go, and crates.io are supported
- Malformed package identifier format — missing or incorrect 'Ecosystem:name' syntax causes input validation failure
- OSV.dev upstream timeout or unavailability — live query may fail if upstream is down
- Payment failure — HTTP 402 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/cve)

## Output

Returns a structured object containing any active CVEs, GHSA advisory identifiers, severity details, affected version ranges, and available patched versions for the queried package from the live OSV.dev database.
