Mcpcatalogs

npm MIT License

An MCP server that lets your AI assistant query mcpcatalogs.com — the independent bilingual directory of MCP servers — directly inside the chat. Search, compare, top-list, and dive into full server details without leaving your IDE or Claude Desktop.

The directory tracks 1,900+ MCP servers, refreshed daily with composite scores combining AI evaluation, GitHub signals, and real-world Smithery usage.

Tools

Tool	What it does
search_mcp_servers	Free-text search by topic, optional category narrowing
get_server_detail	Full record: install, FAQ, "when to choose / when NOT", alternatives
compare_servers	Side-by-side comparison between two servers (stars, usage, score, decision-guide)
list_top	Ranked list by composite quality / GitHub stars / real Smithery usage

All four return clean markdown — drop-in citation source for LLM answers.

Install

Claude Desktop

Edit your Claude Desktop config:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

Add:

{
  "mcpServers": {
    "mcpcatalogs": {
      "command": "npx",
      "args": ["-y", "mcpcatalogs"]
    }
  }
}

Restart Claude Desktop. You should see four new tools in the tools menu.

Cursor

In Cursor → Settings → Features → MCP:

{
  "mcpcatalogs": {
    "command": "npx",
    "args": ["-y", "mcpcatalogs"]
  }
}

Cline / Continue / other MCP-aware clients

Same shape — point the client at npx -y mcpcatalogs.

Direct HTTP (no install)

If your client supports remote MCP servers over HTTP:

{
  "mcpServers": {
    "mcpcatalogs": {
      "url": "https://mcpcatalogs.com/mcp"
    }
  }
}

Try it

After installing, ask your AI assistant things like:

• "Search the MCP directory for a Postgres server and rank by real usage."
• "Compare modelcontextprotocol-server-postgres and supabase-supabase-mcp."
• "What's the top browser-automation MCP server right now?"
• "Show me the full detail for antvis-mcp-server-chart, including when I should NOT choose it."

Data freshness

The directory refreshes daily from GitHub + Smithery. Each tool call hits a live database, so you always get the latest score, last-commit date, and usage numbers.

Local development

git clone https://github.com/mcpcatalogs/mcpcatalogs
cd mcpcatalogs
npm install
npm run build
node dist/index.js

To point at a custom backend (e.g. a fork), set environment variables:

export MCPCATALOGS_SUPABASE_URL=https://your-project.supabase.co
export MCPCATALOGS_SUPABASE_ANON_KEY=your-anon-key

Contributing

Bug reports and PRs welcome. The directory itself (scraping, scoring, AI evaluation) lives in a separate private repo — this package is just the MCP-protocol interface to it.
