MCP サーバー RubyGems

mcp-server-rubygems

A Model Context Protocol server for fetching rubygems metadata via rubygems.org API.

This MCP server provides the following tools for interacting with the RubyGems.org API:

Tool	Description
`get_rubygem_info`	Get information about a RubyGem
`search_rubygems`	Search for RubyGems matching a query string
`get_gem_versions`	Get all available versions of a specific RubyGem
`get_gem_reverse_dependencies`	Get gems that depend on a specific RubyGem
`get_owner_gems`	Get all RubyGems owned by a specific user or organization
`get_gem_owners`	Get the owners of a specific RubyGem

Install dependencies:

npm install

Build the server:

npm run build

For development with auto-rebuild:

npm run watch

To use with Claude Desktop, add the server config:

On MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json On Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "mcp-server-rubygems": {
      "command": "/path/to/mcp-server-rubygems/build/index.js"
    }
  }
}

It should be similar on MCP clients like Cursor, Cline, etc -- just add the command from above in your config.

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:

npm run inspector

The Inspector will provide a URL to access debugging tools in your browser.

security – no known vulnerabilities

license - not found

quality - confirmed to work

remote-capable server

The server can be hosted and run remotely because it primarily relies on remote services or has no dependency on the local environment.

RubyGems.org API と対話して Ruby パッケージに関するメタデータを取得したり、gem を検索したり、依存関係や所有権の情報を調べたりできるモデルコンテキストプロトコルサーバーです。
