About Open Source Network

Open Source Network is a Model Context Protocol (MCP) server that gives Claude Code structured knowledge of 244 open-source tools — enabling intelligent stack recommendations, tradeoff analysis, and ecosystem navigation.

What it does

When you add Open Source Network to Claude Code, you unlock a curated database that Claude can query when you ask questions like "what's the best message queue for a Python microservice?" or "compare Prometheus vs Datadog for a 10-person startup."

Unlike generic web search, Open Source Network provides structured, consistent data across 244 tools with 51 fields each — RAM requirements, scaling patterns, ecosystem relationships, anti-patterns, and more.

Installation

One-line install 
claude mcp add open-source-network npx open-source-network-mcp

That's it. No API keys, no configuration, no network requests at query time. Pure local JSON.
