What can it do?

Quick Start

1. Get an API key

Sign up at filtrix.net, then generate an API key in your account settings.

2. Configure Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "filtrix": {
      "command": "uvx",
      "args": ["filtrix-mcp"],
      "env": {
        "FILTRIX_API_KEY": "flt_your_key_here"
      }
    }

3. Restart Claude Desktop

The Filtrix tools will appear automatically.

Usage Examples

Once configured, ask Claude things like:

• "What happens historically when a stock gaps up 30% with a float under 10M shares?"
• "Show me the last 20 stocks that gapped up over 50%"
• "Look up NVDA ticker info"
• "What filters are available for backtesting?"

Alternative: pip install

pip install filtrix-mcp

Then run manually:

export FILTRIX_API_KEY="flt_your_key_here"
