MCP Radar 🛰️
MCP Server quality radar — find the trustworthy MCP server out of 20,000+, and avoid the 98% that nobody ever installs.
Dataset: 19,947 approved MCP servers (scraped from mcp-marketplace.io, 2026-08-25)The problem: 98% of servers have zero installs, 91% pile into "Developer Tools", only 0.1% are paid, and a single server's schema can burn 47K tokens before you even ask a question.
What it does
Works inside any MCP client (Claude Desktop / Cursor / Claude Code / etc.):
search_servers— search high-quality servers by keyword/category, ranked by an open quality scoreaudit_server— audit any single server before you install: 5-dimension score breakdown, installs, stars, security level, links
Scoring model (out of 100, open & reproducible)
| Dimension | Weight | Meaning |
|---|---|---|
| Heat | 25% | log-normalized install count |
| Security | 25% | marketplace security_score |
| Quality | 25% | avg rating + creator reputation grade |
| Activity | 15% | recency of last update (decay) |
| Official | 10% | official/featured bonus (marketplace self-owned excluded to avoid bias) |
Quick start
pip install -r requirements.txt # installs the MCP SDK (mcp==1.29.1)
python mcp_radar_server.py --stats # print dataset stats
python mcp_radar_server.py # run as a stdio MCP server
Claude Desktop config (claude_desktop_config.json):

"mcp-radar": {
"command": "python",
"args": ["/absolute/path/mcp_radar_server.py"],
"env": { "PYTHONUNBUFFERED": "1" }

Roadmap
- Per-server token cost estimation (schema-size proxy)
- Deep rankings for non-Developer-Tools categories (the underserved niches)
- Web leaderboard page (GitHub Pages)
