What is the Kael MCP server?

Kael MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. AI-native tool server: web fetch, screenshot, search, PDF, DNS, WHOIS, IP geo, code exec & more.

What you get

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

  • 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

What the assistant can call

Once Kael is connected, these are the calls the assistant has available:

  • dns_lookup — Useful when you want: - machine-checkable infrastructure facts - small outputs that a model can quote directly - an easy first connectivity test
  • web_fetch — Useful when you want: - readable page content instead of raw HTML - a compact artifact for summarization - a lower-token input for downstream
  • html_extract — Useful when you want: - page structure as data before reasoning - table/list extraction without custom scraping glue - cleaner agent pipelines
  • code_run — Useful when you want: - deterministic transforms or calculations - reproducible parser behavior - concrete execution evidence instead of simulated

Setting it up

Installation goes through your MCP client rather than a global install: point it at @modelcontextprotocol/inspector on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

Choosing this one

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Kael's toolset — dns_lookup, web_fetch, html_extract and 1 more — is a fair guide to whether it matches your workflow. It is maintained by dreamingms; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against Kael's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Before you rely on it

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the kael mcp server does with a few real requests.

Available tools

ToolWhat it does
dns_lookupUseful when you want: - machine-checkable infrastructure facts - small outputs that a model can quote directly - an easy first connectivity test after listTools
web_fetchUseful when you want: - readable page content instead of raw HTML - a compact artifact for summarization - a lower-token input for downstream reasoning
html_extractUseful when you want: - page structure as data before reasoning - table/list extraction without custom scraping glue - cleaner agent pipelines: fetch/extract first, summarize second
code_runUseful when you want: - deterministic transforms or calculations - reproducible parser behavior - concrete execution evidence instead of simulated code reasoning

How to install the Kael MCP server

Or add to `.claude/settings.json`:

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

Configuration as documented by the project. Restart the client after saving.

Example prompts to try

  • Use Kael to dns lookup.
  • Use Kael to web fetch.
  • Use Kael to html extract.

Frequently asked questions

It connects Kael to MCP-compatible AI assistants such as Claude and Cursor, exposing 4 tools (dns_lookup, web_fetch, html_extract, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Kael directly.
