Local Server (stdio)

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "frostbyte": {
      "command": "node",
      "args": ["/path/to/frostbyte-mcp/src/index.js"],
      "env": {
        "FROSTBYTE_API_KEY": "your-api-key"
      }
    }
  }
}

Cursor / Windsurf

{
  "frostbyte": {
    "command": "node",
    "args": ["/path/to/frostbyte-mcp/src/index.js"],
    "env": {
      "FROSTBYTE_API_KEY": "your-api-key"
    }
  }
}

npx (no install)

{
  "mcpServers": {
    "frostbyte": {
      "command": "npx",
      "args": ["-y", "github:OzorOwn/frostbyte-mcp"],
      "env": {

}

Get an API Key

# Free — 200 credits, no signup
curl -X POST https://agent-gateway-kappa.vercel.app/api/keys/create

Or omit FROSTBYTE_API_KEY — the server auto-creates a free key on startup.

Examples

Once connected, your AI agent can:

• "What's the geolocation of 1.1.1.1?" → calls geo_lookup
• "Take a screenshot of https://news.ycombinator.com" → calls take_screenshot
• "What's the current Bitcoin price?" → calls crypto_price
• "Run this Python code: print(sum(range(100)))" → calls run_code
• "Scrape the content from https://example.com" → calls scrape_url
• "Look up DNS records for github.com" → calls dns_lookup
• "Convert this CSV to JSON: name,age\nAlice,30\nBob,25" → calls transform_data

Environment Variables

Variable	Description	Default
FROSTBYTE_API_KEY	API key for authentication	Auto-created (free tier)
FROSTBYTE_BASE_URL	Gateway URL	https://agent-gateway-kappa.vercel.app
