AgentRank
Google PageRank for AI agents. A live, daily-updated index of 25,000+ MCP servers and agent tools — scored by real GitHub signals, not just star counts.
Install in 3 Steps
1. Add to your AI tool:
# Claude Code
claude mcp add agentrank -- npx -y agentrank-mcp-server
2. Ask your AI to find a tool:
"Find me an MCP server for database access"
3. Get ranked, current results — automatically.
That's it. No API key, no config, no prompting. Your AI searches the live index whenever it needs a tool.
Why AgentRank?
- Your AI's knowledge is stale. Training data is months old — it can't know if a tool was abandoned last week or if something better shipped yesterday.
- Stars lie. A repo with 2,000 stars and no commits in 18 months isn't production-ready. AgentRank weighs freshness, issue health, and dependents — not just popularity.
- 25,000+ tools, scored daily. The index crawls GitHub nightly. Every recommendation reflects what's happening now.
- Gets smarter with use. Every query surfaces which tools developers actually reach for, sharpening rankings for everyone.

How the Score Works
Five signals, weighted by signal quality:
| Signal | Weight | What it measures |
|---|---|---|
| Freshness | 25% | Days since last commit — stale repos decay fast |
| Issue health | 25% | Closed / total issues — maintainer responsiveness |
| Dependents | 25% | Repos that depend on this — real-world adoption |
| Stars | 15% | Raw popularity signal |
| Contributors | 10% | Bus factor — solo projects score lower |
Scores are recomputed nightly from live GitHub data.
