⚡ 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
