GitHub Dependabot API
Dependabot is a GitHub-native dependency update and security alerting feature accessed entirely via the GitHub REST API — there is no standalone Dependabot API; agents use GitHub API endpoints under /repos/{owner}/{repo}/dependabot/ to manage alerts, auto-dismissals, and update configurations.

⚙ Agent Friendliness
🔒 Security
Fine-grained PATs and GitHub Apps support repository-scoped permissions with explicit Dependabot alerts read/write scope. All traffic over TLS. GitHub's overall security posture applies. Dependabot update secrets are encrypted with repository public key before transmission.
⚡ Reliability
Best When
Best when your codebase is hosted on GitHub and you need agents to automate security alert triage, dependency PR monitoring, and update policy enforcement without a separate SCA tool.
Avoid When
Avoid when your repositories are not on GitHub or when you need deep SCA capabilities (transitive analysis, SBOM generation, license compliance) that Dependabot does not provide.
Use Cases
- • Query all open Dependabot security alerts across a repository to populate a vulnerability tracking dashboard
- • Dismiss or acknowledge specific Dependabot alerts in bulk after security team triage and documented acceptance
- • List Dependabot pull requests across all repositories in an organization to monitor open dependency update backlog
- • Enable Dependabot security updates programmatically for newly created repositories via repository settings API
- • Retrieve GHSA advisory details linked to a Dependabot alert to assess severity and cross-reference affected packages
Not For
- • Non-GitHub repositories — Dependabot is GitHub-exclusive and has no integration path for GitLab, Bitbucket, or self-hosted git servers
- • Real-time vulnerability scanning at artifact build time (use Sonatype Lifecycle, Snyk, or JFrog Xray instead)
- • License compliance analysis beyond the basic dependency update scope Dependabot covers
Interface
Authentication
Accessed via GitHub API using a GitHub Personal Access Token (PAT) or GitHub App installation token. Required scopes: security_events (read/write for alerts) and repo for repository access. GitHub Apps are preferred for agent automation as they support fine-grained repository-level permissions. Dependabot has no independent auth — all access flows through GitHub authentication.
Pricing
Dependabot is included with every GitHub repository at no additional cost. Dependabot version updates (PRs for non-security bumps) are also free.
Agent Metadata
Known Gotchas
- ⚠ Dependabot has no standalone API — agents must use the GitHub REST API and cannot interact with Dependabot independently of a GitHub token with correct scopes
- ⚠ Dependabot alerts are scoped per-repository — listing alerts across an entire organization requires iterating over all repositories, which can be slow and rate-limit-intensive for large orgs
- ⚠ Auto-dismissed alerts (dismissed by Dependabot itself) are distinct from user-dismissed alerts and have different state values — agents must handle both states when filtering active alerts
- ⚠ Dependabot security updates (automatic PRs) require both Dependabot alerts and Dependabot security updates to be enabled separately at the repository level — enabling alerts does not automatically enable PRs
- ⚠ The dependabot/secrets API for managing repository secrets used in Dependabot update jobs requires separate secret_scanning scope and uses libsodium public-key encryption for secret values
