RubyGems MCP — wraps the RubyGems.org public API (free, no auth)
Part of Pipeworx — an MCP gateway connecting AI agents to 1394+ live data sources.
Tools
| Tool | Description |
|---|---|
get_gem | Get full metadata for a published Ruby gem by name. Returns latest version, authors, license, descriptions, download counts, and project/source URLs. Use for "what is gem X?", "tell me about Ruby gem Y", or before calling get_versions/get_dependencies. |
search_gems | Search RubyGems by keyword in name/description. Returns matching gems sorted by relevance with name, version, downloads, and info text. |
get_versions | Get full version history for a Ruby gem. Returns every published version with release date, download count, Ruby version compatibility, and licenses. Use for "what versions of X exist?" or "when did Y release version Z?". |
get_dependencies | Get the runtime and development dependencies for a specific version of a Ruby gem. Returns each dependency with its version requirement string. Omit version to get the latest. |
get_reverse_dependencies | List gems that depend on this gem. Useful for understanding ecosystem impact ("what depends on Rack?") or risk surface ("how many gems would break if this one had a vulnerability?"). API caps at 50 names per request. |
Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"rubygems": {
"url": "https://gateway.pipeworx.io/rubygems/mcp"
}
}
}
Or connect to the full Pipeworx gateway for access to all 1394+ data sources:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Using with ask_pipeworx
Instead of calling tools directly, you can ask questions in plain English:
ask_pipeworx({ question: "your question about Rubygems data" })
The gateway picks the right tool and fills the arguments automatically.
