Kael MCP Server
A practical toolkit that offloads expensive LLM operations to cheap compute. Ships 16 tools across three categories: web ops (fetch, search, screenshot, PDF extraction), infrastructure lookups (DNS, WHOIS, IP geo), and utilities (sandboxed code execution, text diff, JSON query). The pitch is clear: use real tools for fetching live data and structured output instead of burning tokens on model guesswork. Supports both SSE and streamable HTTP transports with hosted endpoints at kael.ink, so you can wire it into Claude Desktop or any MCP client without running your own infrastructure. Free tier available. Best for agents that need fresh external data or deterministic execution, not pure reasoning tasks.

Readme
⚡ Kael MCP Server
AI-native tools for agents — use cheap compute for web, DNS, WHOIS, screenshots, extraction, and sandboxed code execution instead of spending model tokens on guesswork.
Kael is for tasks where an agent needs fresh external data, structured output, or real execution — not another paragraph of reasoning.
Why this exists
LLMs are expensive at:
- fetching and cleaning live web content
- checking DNS / WHOIS / IP facts
- extracting structured data from messy pages
- executing code safely and reproducibly
- producing screenshots or binary artifacts
Kael turns those jobs into real tools with JSON output.
Best fit
Use Kael MCP when your agent needs:
- fresh data from the web or internet infrastructure
- structured results instead of prose
- deterministic execution instead of model simulation
- lower token burn on repetitive utility work
- small tool outputs that are easier to feed back into a model
