A Model Context Protocol (MCP) server that enables AI assistants and agents (Claude, Cursor, Copilot, etc.) to search package registries and retrieve up-to-date package information.
Alternatively, in Cursor, you can configure MCP servers in your settings:
Cmd/Ctrl + ,)package-registrynpx["package-registry-mcp"]For Claude Code, run the following command in your terminal:
claude mcp add -s user package-registry npx package-registry-mcp
After configuration, you'll have access to package search and information tools.
Add this server to your Claude Desktop by adding the following to your
claude_desktop_config.json:
{
"mcpServers": {

"command": "npx",
"args": ["package-registry-mcp"]
}
}
}
The config file is typically located at:
~/Library/Application Support/Claude/claude_desktop_config.json%APPDATA%\Claude\claude_desktop_config.jsonAfter adding the configuration, restart Claude Desktop.
