search_npm_packages
Search for npm packages
LABSCO SUMMARY
The "does a package already exist for this" question gets answered without leaving the session.
search_npm_packages takes a query and returns matching npm packages, which is the whole of it — enough to settle a build-or-install decision mid-conversation. There is no tool here for a specific package's versions, downloads or metadata: the surface is search, and anything past the shortlist still means opening the package page.
What it is
A one-tool server that runs an npm package search for a query string.
What you get
- npm packages matching a query string, searched from the client
Requirements
Nothing — no account, no key. The one tool takes a query string.
Setup effort
One command — npx -y npm-search-mcp-server
USE CASES
01
Finding out whether a library already exists before writing one
