⚡ Kael MCP Server

AI-native tool provider — cheap compute beats expensive tokens.

Why burn $0.05 in tokens for your AI to "think through" a DNS lookup when Kael can do it for $0.001?

What is this?

An MCP (Model Context Protocol) server that provides 13 real-world tools for AI agents. Things that are expensive for LLMs to do with tokens, but trivially cheap for a server to do with compute:

Tool Description Why it saves tokens
web_fetch Fetch any URL → clean markdown ~5,000 tokens saved
screenshot Webpage → PNG screenshot ~10,000 tokens saved
web_search Real-time search results Impossible with tokens
html_extract HTML → structured JSON ~8,000 tokens saved
pdf_extract PDF URL → extracted text ~20,000 tokens saved
dns_lookup A/AAAA/MX/TXT/NS/CNAME/SOA/SRV Impossible with tokens
whois Domain registration data Impossible with tokens
ip_geo IP → country, city, ISP, coords Impossible with tokens
code_run Execute JS/Python/Bash in sandbox ~2,000 tokens saved
url_unshorten Follow redirects → final URL ~500 tokens saved
text_diff Unified diff of two texts ~3,000 tokens saved
json_query Dot-notation JSON extraction ~1,000 tokens saved
hash_text MD5/SHA1/SHA256/SHA512 hashing ~200 tokens saved

Quick Start

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "kael-tools": {
      "url": "https://www.kael.ink/mcp/sse"
    }
  }
}

Any MCP Client (Node.js)

import { Client } from "@modelcontextprotocol/sdk/client/index.js";
import { SSEClientTransport } from "@modelcontextprotocol/sdk/client/sse.js";

const transport = new SSEClientTransport(new URL("https://www.kael.ink/mcp/sse"));
const client = new Client({ name: "my-app", version: "1.0" });
await client.connect(transport);

// List available tools
const tools = await client.listTools();

// Call a tool
const result = await client.callTool({
  name: "dns_lookup",
  arguments: { domain: "example.com", type: "MX" }
});

Direct REST API

All tools are also available as REST endpoints at https://www.kael.ink/api/:

Pricing

  • Free tier: 100 calls/day (no key needed)
  • Pro: Unlimited — $9.99/month
  • Enterprise: Custom pricing

Why Kael?

  1. Built for AI agents, not humans — structured JSON output, minimal token overhead
  2. Always fresh data — DNS, WHOIS, geo, search results are real-time
  3. Cheaper than thinking — Why simulate code execution when we can actually run it?
  4. 13 tools and growing — New tools added regularly
  5. Standard MCP protocol — Works with Claude, GPT, any MCP-compatible agent
