NPM Documentation Server

Example Use Cases

• 1

  Fetch README content and metadata (version, dependencies, license, repository) for a specific NPM package to provide contextual help or code suggestions.

• 2

  Check package dependency lists and licenses quickly without repeatedly querying external APIs, using the local SQLite cache to improve latency.

• 3

  Embed package documentation lookups into automated workflows or toolchains (e.g., code assistants, linters, or CI tools) with configurable cache TTL and DB location.

Description

This MCP server retrieves package metadata and README content from the npms.io API and caches results locally using SQLite (better-sqlite3) to improve performance and reduce repeated network calls. It exposes a single MCP tool, getNpmPackageDocs, which returns package details (version, description, dependencies, license, repository, author, and README content). The server is configurable via environment variables (cache TTL, cache DB path, log level) and is intended to be run alongside MCP clients. This makes it easy for agents to quickly obtain package documentation and metadata without hitting external APIs repeatedly.
