Tools

Tool Description
search_packages Search npm for packages by keyword. Returns package names, descriptions, latest versions, publish dates, and publishers. Use when discovering libraries for a task.
get_package Get full details for a specific package: version, description, dependencies, homepage, repository, and license. Use after search_packages to evaluate a candidate package.
get_downloads Fetch npm download counts for a package over a named period (last-day, last-week, last-month, last-year) or a custom date range like "2024-01-01:2024-06-30". Returns total downloads, start date, and end date.
list_versions List published versions of an npm package with publish dates, dist-tags (latest/next/beta), and deprecation notices — answers "what versions of <pkg> exist", "when was <pkg> last published", "is the latest version deprecated". Returns versions newest-first, plus the package created/last-modified timestamps.
get_version_info Get metadata for a SPECIFIC version (or dist-tag) of an npm package: dependencies, dev/peer dependencies, engines, license, tarball + integrity hash + unpacked size, and any deprecation notice. Use for "dependencies of <pkg>@<version>", pinned-version audits, or inspecting a particular release. Version accepts an exact version (e.g. "4.18.2"), a dist-tag (e.g. "latest", "next"), or omit for the latest.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "npm": {
      "url": "https://gateway.pipeworx.io/npm/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 1394+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about Npm data" })

The gateway picks the right tool and fills the arguments automatically.
