deptrust is a CLI that checks package versions for known vulnerabilities across npm, PyPI, crates.io, Go modules, RubyGems, NuGet, Maven, Packagist, pub.dev, CocoaPods, Hex.pm, Hackage, GitHub Actions, and more.
It runs locally as a CLI and as an MCP server. It calls public package registry and OSV APIs directly; there is no hosted deptrust service to trust or configure.
This tool was born out of the frustration that is AI agents constantly using old versions.
Packagist / Composer, using vendor/package package names
pub.dev
CocoaPods
Hex.pm
Hackage
GitHub Actions, using owner/repo package names and tags, branch refs, or commit SHAs as versions
deptrust currently reports known vulnerabilities and gives a simple recommendation:
Highest known severity
Recommendation
critical
block
high
block
medium / unknown
review
low
allow
none found
allow
allow means no blocking known vulnerability was found in the public data sources. It does not prove that a package is safe.
deptrust also emits risk signals that are not CVEs. For example, a version published in the last 72 hours is marked for review so an agent does not blindly install a brand-new release.
Advisory providers are queried in parallel:
OSV
GitHub Advisory Database, including reviewed advisories and malware advisories
Provider coverage varies by ecosystem. If deptrust can resolve registry metadata but no configured vulnerability provider supports that ecosystem, it returns unknown instead of treating the package as safe.

The JSON output includes advisory coverage fields:
skipped_providers: configured providers skipped because the ecosystem is unsupported
advisory_coverage: full, partial, none, or error
advisory_coverage_reason: short explanation for the coverage value
registry_verification: verified when registry metadata confirmed the version, or unverified when an exact-version check continued after a transient registry failure
registry_verification_reason: the registry error when verification was unavailable
An exact-version check still queries advisory providers when registry verification is temporarily unavailable. That result is always non-installable and never receives an allow recommendation. Checks for latest, unknown packages, and definitively nonexistent versions still require successful registry resolution.
HTTP requests retry 429, 502, 503, and 504 responses up to three total attempts. Retries use short exponential delays and honor Retry-After values up to two seconds; longer server-requested waits fail fast so the CLI does not hang. Exhausted advisory retries make the result incomplete and prevent an allow recommendation.
GitHub API authentication
GitHub Advisory Database and GitHub Actions API requests can use a short-lived, least-privilege GitHub App token. In CI, pass it through DEPTRUST_GITHUB_TOKEN:
The credential precedence is DEPTRUST_GITHUB_TOKEN, GITHUB_TOKEN, then GH_TOKEN. For local use, the optional GitHub CLI fallback is enabled explicitly with DEPTRUST_GITHUB_AUTH=gh deptrust check ...; it runs gh auth token without prompting. If no credential is available, DepTrust continues unauthenticated. A GitHub API rate-limit or permission failure produces unknown with diagnostics and is never treated as an OSV-only success.
DepTrust never stores, bundles, caches, logs, telemeters, or emits GitHub tokens. Authentication headers are sent only to https://api.github.com.
CLI Usage
Check an exact version:
deptrust check npm lodash 4.17.20
Example normal response:
npm [email protected]: 2 known vulnerabilities found
recommendation: block
risk_score: 80
For GitHub Actions, full commit SHAs are treated as pinned. Full semver tags such as v4.2.2 are accepted without an extra pinning signal. Major-only tags such as v4 and branch refs such as main are valid refs, but deptrust adds a review signal because they can move.

Suggest the latest version only when no known vulnerabilities are found:
deptrust suggest npm lodash
If the latest version is not allowed, suggest checks older known versions and returns the newest version with an allow recommendation.
When advisories include fixed versions, suggest checks those provider-reported fixed versions first before walking back through the registry version list.
The default installer is guided. It installs the binary, asks which agent integrations to configure, prints the user-level destinations before changing anything, and asks for confirmation. The guided installer defaults to enabling MCP, the skill fallback, and dependency safety hooks for Codex and Claude Code. Add --yes for non-interactive binary-only installs, or pass explicit integration flags.
Rerunning the installer is safe. It silently leaves unchanged MCP, skill, and hook configuration alone. If an integration points at an old deptrust binary or its managed configuration has changed, the installer updates it automatically; users do not need to manually remove and re-add MCP servers. Customized skills are backed up before replacement.
To remove the user-level binary, skill, and MCP entries:
brew tap clidey/tap
brew install deptrust
brew upgrade deptrust
Homebrew prints a reminder after installation. To run the guided Codex and Claude Code setup using the Homebrew binary itself (MCP registrations and dependency safety hooks):
deptrust setup
The guided setup asks before enabling MCP and dependency safety hooks. It leaves registrations that already use the current binary alone, and reconciles existing DepTrust registrations that point to an older npm, Homebrew, or source-install path.
Go users can install directly:
go install github.com/clidey/deptrust/cmd/deptrust@latest
Nix
The project provides optional Nix flake outputs for users who already use Nix. The flake wraps the prebuilt release binary.
# Run without installing
nix run github:clidey/deptrust
# Install into your profile
nix profile install github:clidey/deptrust
The normal release workflow generates the Nix
hashes from the same archives it publishes, evaluates the flake before
publishing, then builds and runs it against the published assets before updating
the default branch. github:clidey/deptrust may briefly lag while that workflow
is running. Release tags point to the source commit from before the generated
flake update and may still reference the previous binary; pin a commit whose
flake.nix contains the version you need when reproducibility matters.
Devbox
For reproducible development environments, use Devbox:
# Install Devbox first (if not already installed)
curl -fsSL https://get.jetify.dev/devbox | bash
# Initialize the environment
devbox shell
# Build the project
devbox run build
devbox.json constrains the toolchain version and the committed devbox.lock
pins the exact package versions and nixpkgs revisions. Run devbox update when
you intentionally want to refresh those pins.
Or install Devbox via Homebrew:
brew install jetify-com/devbox/devbox
Agent Setup
To install deptrust and register everything the installer can configure without the guided prompts:
--all installs the binary, registers Codex MCP when the codex CLI is available, installs the Codex skill fallback, registers Claude Code MCP when the claude CLI is available, and installs the Codex and Claude Code dependency safety hooks.
The hooks are PreToolUse hooks. They check package install commands before they run, and they also check GitHub Actions added to workflow files through agent file-edit tools. A hook blocks the tool call when deptrust returns review, block, or unknown. The installer writes user-level hook config only: ~/.codex/hooks.json for Codex and ~/.claude/settings.json for Claude Code.
When the gh CLI is available, guided setup also offers to use its existing local login for hook checks. This writes only DEPTRUST_GITHUB_AUTH=gh, never a GitHub token, so hook subprocesses can avoid unauthenticated GitHub API rate limits.
After MCP setup, agents will automatically check packages before recommending updates or changes. The MCP server sends instructions to vet all dependency versions — including answering questions like "what can I update" or "which dependencies are safe to upgrade" — before providing recommendations.
If using deptrust in a non-MCP context, remind your agent:
Before listing, comparing, or recommending specific package versions, check them with deptrust. This includes answering "what can I update" — do not provide version recommendations until after checking for known vulnerabilities.
For CI, configure a short-lived least-privilege GitHub App token as DEPTRUST_GITHUB_TOKEN for the process running DepTrust. For local GitHub CLI authentication, use DEPTRUST_GITHUB_AUTH=gh deptrust check .... DepTrust never stores tokens.
Manual MCP Setup
If your client supports stdio MCP servers, configure it to run:
claude mcp add --transport stdio deptrust -- /absolute/path/to/deptrust mcp
On initialize, the server returns MCP instructions telling the agent when to reach for these tools (before adding, bumping, or recommending a dependency, or when asked whether a version is safe to update). Clients that surface server instructions will apply this automatically, so the manual reminder above is optional rather than required.
MCP Tools
check_package
Checks a package version and returns known vulnerabilities plus a recommendation.
version may be omitted or set to latest. If an exact version does not exist, deptrust returns an error and suggests the latest explicit version.
MCP output is intentionally compact so agents can decide whether to install a dependency without pulling full advisory bodies into context. If the user asks to see full details, the agent can run the full_response_command.
Example compact MCP structured output:
{
"ecosystem": "npm",
"package": "vite",
"version": "7.0.0",
"latest_version": "8.0.16",
"known_vulnerabilities_found": true,
"safe_to_use": false,
"should_install": false,
"risk_score": 80,
"classification": "vulnerable",
"recommendation": "block",
"reason": "Found 7 known vulnerability records.",
"next_action": "do_not_install; use suggest_safe_version or compare_versions to choose a safer version",
"summary": "vite 7.0.0 has 7 known vulnerabilities, including high severity. Block this exact version and prefer a fixed release.",
"vulnerability_count": 7,
"vulnerability_counts": {
"critical": 0,
"high": 2,
"medium": 3,
"low": 2,
"unknown": 0
},
"highest_severity": "high",
"checked_providers": [
"OSV",
"GitHub Advisory DB"
],
"skipped_providers": [],
"advisory_coverage": "full",
"advisory_coverage_reason": "all configured vulnerability providers were checked",
"registry_verification": "verified",
"full_response_command": "deptrust check --json npm vite 7.0.0"
}
The compact MCP response omits the vulnerability array, advisory details, and repeated references. Agents should use the counts, highest severity, provider coverage, recommendation, and next action by default. If the user asks for full advisory details, run the full_response_command.
When GitHub advisory access is rate-limited or unavailable, MCP returns unknown. The agent should proactively offer to configure a token and retry, skip or defer the version, or proceed only after the user explicitly accepts the unresolved GitHub coverage risk for that exact version. That exception must remain clearly labeled as user-accepted uncertainty; it must not be reported as allow or as proof that the version is safe.
suggest_safe_version
Checks the latest version first. If latest is not allowed, checks provider-reported fixed versions first, then older known versions, and suggests the newest version with an allow recommendation.
{
"ecosystem": "npm",
"package": "lodash"
}
compare_versions
Compares a current version and target version, including resolved and added vulnerabilities.
If you do not want MCP, install the bundled Codex skill:
npx @clidey/deptrust skills install
The skill tells Codex to call the deptrust CLI before installing, updating, or recommending npm, PyPI, Cargo, Go module, RubyGems, NuGet, Maven, Packagist, pub.dev, CocoaPods, Hex.pm, Hackage, and GitHub Actions packages.
Troubleshooting
If deptrust is not found:
export PATH="$HOME/.local/bin:$PATH"
If an MCP client cannot start the server, find the full path:
which deptrust
Then put that absolute path in the MCP config.
If a package check returns unknown, do not treat the package as safe. It means deptrust could not get a complete answer from an advisory provider or could not verify the exact version with its registry.
