# 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 PyPI, npm, Go, or Rust 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-a3a7009b
```

Example prompt: Check if the PyPI package 'requests' has any active 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 live, real-time vulnerability data directly from Google OSV.dev for open-source packages across PyPI, npm, Go, or Rust ecosystems. Prefer it over static advisory databases when you need up-to-date CVE and GHSA records and patched version guidance without standing up your own OSV integration. It is especially useful in CI/CD pipelines, dependency audits, or agent-driven security reviews where freshness of vulnerability data matters.

## Known failure modes

- Package not found in OSV.dev for the specified ecosystem — returns empty advisory list
- Malformed package identifier format — missing or incorrect ecosystem prefix causes validation error
- OSV.dev upstream unavailable — returns service error or timeout
- Payment not completed (HTTP 402) — endpoint requires $0.01 USDC per call via x402 protocol
- Invalid ecosystem name — only PyPI, npm, Go, and crates.io are supported

## 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/pypi-vuln-scan)

## Output

Returns a structured object containing active vulnerability records from OSV.dev for the queried package, including CVE IDs, GHSA advisory identifiers, severity information, affected version ranges, and recommended patched versions.
