Common questions

Is Æfact — Korean fact desk for AI agents safe?

It passed 4 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed 21 days ago, and the latest version (0.4.1) reached the registry 21 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?

Æfact MCP — Korean fact desk for AI agents

Æfact (에팩트뉴스) is a read-mostly Model Context Protocol server that gives AI agents verified, dated Korean public facts:

  • What changes when — Korean laws and regulations taking effect, with the official amendment reason and changed wording quoted verbatim from the Ministry of Government Legislation (법제처).
  • Korea's numbers — Bank of Korea indicators (base rate, FX, CPI and ~100 more) with the date they are valid from.
  • Fact-check requests — send one claim; decidable claims are checked against primary data immediately and published at a public URL with a citation line.

Verdicts are computed by rules and arithmetic against primary sources. No language model decides a verdict.

  • Website: https://aefact.site
  • MCP endpoint (Streamable HTTP, stateless, no auth): https://aefact.site/mcp
  • Official MCP Registry: site.aefact/aefact
  • Agent guide: https://aefact.site/skill.md · https://aefact.site/llms.txt

This repository contains documentation and registry metadata only. The server runs at aefact.site.

  2. Bank of Korea base rate — e.g. "기준금리는 연 3.00%다"
  3. Monthly consumer price inflation (YoY) — e.g. "9월 소비자물가 상승률은 2.9%다"
  4. Arithmetic inside the sentence (changes, shares, sums) — e.g. "1명으로 전년(25명)보다 96% 감소"

Other claims are accepted as queued and counted as demand. Claims containing personal data, or about elections/politics, ongoing investigations or trials, personal medical advice, or celebrity private life are not accepted. Results are public; reported results are hidden immediately pending human review.

Verdicts

사실 (supported) · 대체로 사실 (mostly supported — some figures not checked) · 사실과 다름 (contradicted) · 근거 부족 (insufficient evidence) · 검증 불가 (unverifiable). 계산 맞음 means only the in-sentence arithmetic was checked. Automatic mismatches are shown as 사람 확인 중 (awaiting human review) rather than 사실과 다름.
