Overview

AI-generated overview

A local MCP server that lets an AI assistant search npm, inspect package details, compare packages, check download stats and list dependencies.

What you can do
Search npm packages by keyword and get detailed package info such as version, license, maintainers and dependencies. Check download statistics by day, week, month or year, and list recent versions of a package. Compare two packages side by side and list all dependencies of a package.
When to use it
Useful when choosing between JavaScript packages, checking how popular or actively maintained a library is, or reviewing a package's dependencies and versions before adding it to a project.
Requirements
Runs locally over stdio, typically launched with npx, so Node.js and network access to npm are needed. No API keys or environment variables are required.
Before you install
Read-only lookups against public npm data; no credentials, payments or write actions are involved. Package details and download figures come from npm and should be verified before relying on them.

Installation

In SourceWeft

  1. Open Npm Search in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
