devstack-mcp
A remote MCP connector that exposes DevStack API endpoints as typed tools for LLM agents. It provides normalized access to developer registry data across npm, PyPI, Docker Hub, and VS Code Marketplace, including package search, details, versions, download stats, dependency graphs, and vulnerability insights.
Endpoint and access
No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.
https://devstack-mcp.vercel.app/mcpWhat its tools do
10 tools, grouped by the hints the server advertises. Hints are self-declared, not verified behavior.

get_package — Get normalized package details
Full normalized details for one package by registry + name, in a single unified Package shape across npm, PyPI, Docker Hub, and the VS Code Marketplace. name handles scoped npm ids (e.g. @types/node), Docker namespaces (e.g. library/nginx or a bare nginx for official images), and VS Code publisher.extension ids. With registry=all the request fans out to every registry in parallel and returns a packages array (missing registries are silently dropped); otherwise a single package is returned.

}search_packages — Search packages across registries
Search a registry for packages matching q. registry=all fans out to npm, Docker Hub, and the VS Code Marketplace and merges the results. PyPI has no public search API, so registry=pypi returns 400 not_supported — look a PyPI package up by name via get_package instead. Results are normalized PackageSummary items (npm adds a relevance score; Docker adds isOfficial).

}get_versions — Get published versions / tags
List published versions (npm/PyPI), image tags (Docker Hub, most recent 25), or extension versions (VS Code) for a package. registry=all is NOT supported here — pick a single registry. Each item carries version and released, plus registry-specific extras (files for PyPI, size for Docker tags).

}get_downloads — Get download / pull statistics
Download statistics for a package. Only npm (via api.npmjs.org) and PyPI (via pypistats.org) support this; any other registry returns 400 not_supported. npm returns a period window with downloads, start, and end; PyPI returns last_day, last_week, and last_month totals.

}get_dependency_graph — Get resolved dependency graph
The fully resolved dependency graph for one exact package version, via deps.dev. Returns a flat nodes[] array plus integer-index edges[] (walk from/to to rebuild the tree). Each node carries relation (self | direct | indirect) and a direct boolean; node[0] is always the queried root (relation: self). Node order is NOT stable — look nodes up by name/relation, never by positional index. system is case-insensitive and lowercased (npm, pypi, cargo, go, maven, nuget). version is REQUIRED (a graph is resolved for one exact version).

}get_vulnerabilities — Get vulnerabilities for a package
Known vulnerabilities (CVE / GHSA / PYSEC / GO advisories) for a package, via OSV.dev. Pass version to filter to advisories affecting that exact version, or omit it for the package's full advisory history. Each result carries the OSV id, cross-id aliases, a severity word grade (LOW|MODERATE|HIGH|CRITICAL), the cvss vector string, affectedRanges with fixed-version events, references, and cwes. A clean package returns count: 0 with an empty list (not an error). ecosystem is CASE-SENSITIVE — use OSV's spelling (npm, PyPI, Go, crates.io, Maven, NuGet, RubyGems, …). Use scan_vulnerabilities_batch for lockfile batch scans.

}scan_vulnerabilities_batch — Batch vulnerability scan (lockfile)
Scan many packages in one call — ideal for a whole lockfile. Pass a queries[] array (max 100) of { ecosystem, name, version? }; results are returned positionally aligned, one row per query, each with a count and a hydrated vulns[] array. Advisories are de-duplicated and hydrated across the batch. ecosystem is CASE-SENSITIVE (OSV spelling).

}get_insights — Get project insights — OSSF Scorecard + repo signal
Health and security insights for a package's source project, via deps.dev. Returns the linked source repository, GitHub stars/forks/openIssues, licenses, resolved dependencyCount, security advisories, and the full OSSF Scorecard (ossfScore 0..10 plus the per-check breakdown). Omit version to use the registry default version — note deps.dev's default is a MOVING target and an unverified default mirror may have no computed scorecard (ossfScore: null); pin version for a stable, scorecard-backed result. system is lowercased (npm, pypi, cargo, go, maven, …).

}search_ecosystems — Cross-registry package lookup (50+ ecosystems)
Look a package name up across 50+ registries at once, via ecosyste.ms. This is an EXACT-name lookup (not fuzzy full-text): q=react returns the react package everywhere it exists (npm, cargo, nuget, pub, bower, …), each as a normalized ecosystemsPackage with reverse-dependency counts. Pass ecosystem to narrow to one registry. Results carry dependentReposCount, dependentPackagesCount, and vulnerabilityCount.

}get_ecosystems_package — Get one package on one registry (with reverse-dep counts)
Full normalized metadata for one package on one of 50+ registries, via ecosyste.ms — including the fields v1 registries can't give you: dependentReposCount and dependentPackagesCount (reverse dependencies), ecosystem, and vulnerabilityCount. Scoped/namespaced names are handled automatically. Returns 404 if the package does not exist on that ecosystem.
