oosmetrics - Open Source Momentum Intelligence

Query growth metrics, compare repos, discover trending projects, find alternatives, and get AI-powered deep analysis for 330,000+ GitHub repositories tracked by oosmetrics.com.

How it works

This skill runs the @oosmetrics/mcp npm package (source: https://github.com/AlessandroFlati/GitHubMetrics/tree/main/mcp) as a local MCP server over stdio. The server makes HTTPS requests only to api.oosmetrics.com using your API key. It does not listen on any ports, does not run in the background after the agent session ends, and does not collect telemetry or send data anywhere other than the oosmetrics API.

Setup

1. Get your API key at https://oosmetrics.com/profile (Pro or AI tier required). The key is scoped to your account and can be rotated or deleted at any time from your profile page.
2. Set the environment variable: export OOSMETRICS_API_KEY=oosm_your_key_here
3. The MCP server is installed via npx @oosmetrics/mcp@1.0.1 and starts automatically when this skill is loaded. It communicates with the agent over stdio (no network ports opened locally).

Tools

The available tools depend on your subscription tier. The server fetches the tool list from the oosmetrics API at startup, so Pro users see 7 tools and AI users see all 10.
