# 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 for live CVE and GHSA vulnerability advisories for a named PyPI, npm, Go, or Rust crate package, returning active vulnerabilities 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-26e6af95
```

Example prompt: Can you check if the npm package lodash has any known CVEs or GHSA security advisories, and tell me which versions have fixes?

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data from Google OSV.dev for open-source packages across PyPI, npm, Go modules, or Rust crates. It is preferable over static databases or periodic snapshots when freshness matters — e.g. in CI/CD pipelines, pre-release audits, or agent-driven dependency reviews. It covers multiple ecosystems in a single API with a simple package identifier input.

## Known failure modes

- Unknown or misspelled package name returns empty results or an error
- Unsupported ecosystem prefix causes a validation error
- OSV.dev upstream API downtime results in a timeout or 5xx error
- Package exists but has no known vulnerabilities — returns empty advisory list (not an error)
- Missing required 'package' parameter returns a 400 bad request

## 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/npm-vuln-scan)

## Output

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