Tool Discovery MCP Server

An MCP server that searches GitHub in real-time to find developer tools for your workflow pain points. Works with Cursor and other MCP-compatible AI tools.

What It Does

When you ask about tools or describe a workflow issue:

1. Searches GitHub in real-time for relevant tools
2. Filters for quality - only returns tools with 500+ stars, updated in last 2 years
3. Provides tips for tools you're already using (if mentioned)

Why Use This Instead of Just Asking the AI?

• Returns only real tools that exist on GitHub
• Validates quality via star count and recent activity
• Prevents recommendations of abandoned, obscure, or non-existent tools
• Provides actual URLs and star counts as quality signals

Installation

Option 1: NPM (Recommended)

No installation needed - just add to your Cursor config.

Add to your ~/.cursor/mcp.json:

{
  "mcpServers": {
    "tool-discovery": {
      "command": "npx",
      "args": ["-y", "tool-discovery-mcp"]
    }
  }
}

Then restart Cursor (or toggle the MCP server off/on in settings).

Option 2: From Source

git clone https://github.com/mathonsunday/tool-discovery.git
cd tool-discovery
npm install
npm run build

Add to your ~/.cursor/mcp.json:

{
  "mcpServers": {
    "tool-discovery": {
      "command": "node",
      "args": ["/path/to/tool-discovery/dist/index.js"]
    }
  }
}

Usage

Just ask naturally in Cursor agent mode:

• "Is there a tool for pomodoro/focus timers?"
• "Find me a CSS animation library"
• "I need a better way to manage git branches"
• "What tools exist for API testing?"

The AI will automatically call discover_tools and present the results.
