DepScope is a package intelligence MCP server providing 22 tools across 19 ecosystems, helping AI agents make safe, informed dependency decisions by preventing hallucinations, catching vulnerabilities, and stopping supply-chain attacks.

Security & Safety

• Malware detection — Check packages against OpenSSF/OSV malicious package lists

• Typosquat detection — Identify if a package name is a typosquat (e.g. lodsh vs lodash)

• Vulnerability lookup — Retrieve CVEs/OSV advisories with CVSS scores and fix versions

• Bulk pre-flight check — Batch validate multiple packages at once (existence, typosquats, malicious flags)

Package Intelligence

• Full health report — Machine-readable JSON with score, vulnerabilities, maintainers, and recommendation

• LLM-optimized brief — Plain-text summary with ~75% fewer tokens and a SAFE/AVOID/URGENT/MALICIOUS verdict

• Health score — Quick 0–100 score for go/no-go decisions

• Package existence check — Boolean guard against hallucinated package names

• Latest version — Latest published version and deprecation status

• Install commands — Canonical install commands across package managers

Vulnerability & Version Management

• Pin safe version — Find the highest version below a chosen CVE severity tier within semver constraints

• Breaking changes — List breaking changes between two major versions

• Migration path — Prescriptive plan (with code diffs) for switching to a replacement package

• Known bugs — Non-CVE bugs for a specific package version

Project & Stack Analysis

• Scan project — Audit a full dependency list with per-package health and prioritized actions (REMOVE NOW / URGENT / REPLACE / REVIEW)

• Compare packages — Side-by-side comparison of 2–10 packages (health, vulns, downloads, maintainers)

• Check compatibility — Verify if a multi-package version combination works together

• Find alternatives — Curated replacements for deprecated or unhealthy packages

Trust, Discovery & Support

• Trust signals — Maintainer bus factor, OpenSSF Scorecard, quality metrics, and SLSA/Sigstore provenance

• Resolve errors — Map error messages or stack traces to verified fixes

• Trending packages — Live trending packages with rank-delta and weekly growth metrics

• Submit tickets — Report bugs, security findings, anomalies, or partnership inquiries
