# 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-security.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Queries Google OSV.dev to return active CVEs, GHSA advisories, and patched versions for a given PyPI, npm, Go, or Rust crate 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-security-agentdiet-dev-real-time-open-source-package-cve-ghsa-f2a20d19
```

Example prompt: Can you check if the npm package lodash has any active CVEs or GHSA security advisories right now, and tell me what the patched version is?

## When to prefer this

Choose this endpoint when you need live, authoritative CVE and GHSA vulnerability data for open-source packages across PyPI, npm, Go, or Rust ecosystems specifically sourced from Google OSV.dev. Prefer it over static advisory databases when you need real-time patched version information and zero-day coverage without maintaining your own vulnerability feed.

## Known failure modes

- Package not found in OSV.dev — returns empty or no-vulnerability result for unknown package names
- Malformed package identifier (missing ecosystem prefix) may return incorrect or no results
- OSV.dev upstream unavailability could cause timeout or error responses
- Ecosystem not supported (e.g. Java Maven, Ruby gems) may yield no results
- Payment failure via x402 returns HTTP 402 before query is executed

## 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-security.agentdiet.dev/v1/zero-day-advisories)

## Output

Returns a structured response containing active CVE identifiers, GHSA advisory references, affected version ranges, severity information, and available patched versions for the queried package, sourced live from Google OSV.dev.
