Snyk CLI for AI Agents — Security Scanning by AI
Let your AI agent scan your code, containers, and infrastructure for security vulnerabilities
Browse all CLI tools for AI agents
What your agent can do
You merge a PR that updates three dependencies. Somewhere in the transitive dependency tree, one of those updates pulls in a package with a known remote code execution vulnerability. `npm audit` might catch it. Or it might not — npm audit misses vulnerabilities in non-npm ecosystems and provides less actionable output. Your agent runs `snyk test --json` and gets structured vulnerability data with severity, exploit maturity, and specific upgrade paths.Snyk CLI scans four attack surfaces from one tool. Application dependencies (`snyk test`) across npm, pip, Maven, Go, Ruby, and more. Container images (`snyk container test`) for OS and application-layer vulnerabilities. Infrastructure-as-code (`snyk iac test`) for Terraform, CloudFormation, and Kubernetes misconfigurations. Source code (`snyk code test`) for SAST findings. Your AI agent runs all four in CI and gets a complete security picture.Exit codes make Snyk naturally agent-native. 0 = clean. 1 = vulnerabilities found. 2 = error. Your agent gates deployments on exit codes without parsing output. When vulnerabilities are found, the `--json` output provides structured data: vulnerability ID, severity, affected package, fix version, and exploit maturity. The agent decides which findings block deployment and which are acceptable risk.SARIF output connects Snyk directly to GitHub Code Scanning. `snyk test --sarif` produces results that upload to GitHub's security tab, appearing as annotations on pull requests. Your agent automates the entire flow: scan, upload, and developers see security findings inline with their code review.
Frequently asked questions
- Can AI agents automate security scanning with Snyk?
- Yes. Snyk runs fully non-interactive with `SNYK_TOKEN`. Every scan supports `--json` (structured data) and `--sarif` (GitHub Code Scanning format). Exit codes indicate results (0=clean, 1=vulns, 2=error). Your agent scans dependencies, containers, Terraform, and source code in CI pipelines. Install with `brew install snyk` or `npm install -g snyk`.
- What does Snyk scan that npm audit doesn't?
- Snyk scans beyond npm: Python (pip/pipenv/poetry), Go modules, Java (Maven/Gradle), Ruby (Bundler), .NET (NuGet), and more. It also scans Docker container images, infrastructure-as-code (Terraform/CloudFormation/K8s), and source code (SAST). Snyk provides exploit maturity data and specific fix versions. npm audit covers npm packages only.
- How does Snyk CLI fit into CI/CD pipelines?
- Set `SNYK_TOKEN` as a CI secret. Run `snyk test --json` to scan and get structured results. Use exit code 1 to fail the build on vulnerabilities. Upload SARIF to GitHub Code Scanning for PR annotations. Run `snyk monitor` post-deploy for continuous vulnerability tracking. Works with GitHub Actions, GitLab CI, Jenkins, and any CI provider.
