# 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 live OSV.dev vulnerability intelligence for a named package (PyPI, npm, Go, crates.io) and returns active CVEs, GHSA advisories, and patched versions.

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-cae6b827
```

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

## When to prefer this

Choose this endpoint when you need live, up-to-date CVE and GHSA vulnerability data for open-source packages in PyPI, npm, Go, or crates.io ecosystems — especially when freshness matters and you need patched version recommendations. Prefer it over static NVD snapshots or local dependency scanners when you need real-time OSV.dev intelligence without maintaining your own vulnerability database.

## Known failure modes

- Unknown or misspelled package name returns no results or an error
- Unsupported ecosystem identifier causes a lookup failure
- OSV.dev upstream API unavailability causes a service error
- Package with no known vulnerabilities returns an empty advisories list
- Malformed ecosystem:name format causes a 400-style validation 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-security.agentdiet.dev/v1/cve-lookup)

## Output

Returns a structured object containing active CVE identifiers, GHSA advisory IDs, affected version ranges, patched/fixed versions, and vulnerability severity metadata for the queried package, sourced live from Google OSV.dev.
