@bradford-tech/npm-package-readme-mcp-server

An MCP server that exposes npm registry data — package READMEs, metadata, and search — to MCP-compatible AI clients.

This is a maintained fork of naoto24kawa/npm-package-readme-mcp-server, republished under the @bradford-tech scope after the original was removed from GitHub and npm. No functional changes from the upstream 0.1.4 release.

Install

npm install -g @bradford-tech/npm-package-readme-mcp-server

Also works with pnpm add -g, yarn global add, or via npx (no install needed).

Configure your MCP client

Add the server to your client's MCP configuration:

{
  "mcpServers": {
    "npm-package-readme": {
      "command": "npm-package-readme-mcp-server"
    }
  }
}

Or run on demand with npx:

{
  "mcpServers": {
    "npm-package-readme": {
      "command": "npx",
      "args": ["-y", "@bradford-tech/npm-package-readme-mcp-server"]
    }
  }
}

Tools

The server exposes three tools to the connected client.

get_readme_from_npm

Fetches a package's README and extracts usage examples. Reads from the npm registry first, falls back to the linked GitHub repository.

Example call:

{ "package_name": "react", "version": "18.2.0" }

get_package_info_from_npm

Returns package metadata and download statistics for the latest version.

Example call:

{ "package_name": "express", "include_dependencies": true }

search_packages_from_npm

Searches the npm registry.

Example call:

{ "query": "testing framework", "limit": 10 }

How package data is fetched

• Package metadata and READMEs come from registry.npmjs.org.

• If the registry response has no README, the server resolves the repository field and fetches the README from the GitHub API.

• Download statistics come from api.npmjs.org/downloads.

• Responses are cached in memory (default TTL: 1 hour; search results: 10 minutes).

GitHub anonymous API requests are rate-limited to 60/hour. The server logs a warning when no token is available but still works for low-volume use.

Requirements

• Node.js >= 18
