Common questions

Is afterns safe?

It passed 3 of 3 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 –, and the latest version (1.0.1) reached the registry 5 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 in developer mode.

What can I use instead?

In the same category: Agent-Native Calendar, Excel MCP Server, MCP Server for Excel

afterns MCP

US stock earnings data for AI assistants. Ask in Korean or English how a stock moved after its earnings, whether it beat estimates, and when it reports next.

  • Remote endpoint (Streamable HTTP): https://afterns.com/api/mcp
  • No sign-in, no API key, read-only
  • Covers 1,270+ US-listed stocks
  • Website: afterns.com

Tools

ToolWhat it returns
get_earnings_reactionsFor each recent report (up to 12 per answer, about three years): the next-day price move, EPS vs. estimate and surprise %, revenue growth, and whether it reported before the open or after the close. Plus how often the stock rose, its average move, how many times it fell after beating estimates, and the next report date in Korea and US Eastern time
get_earnings_calendarUpcoming US earnings for up to 14 days, biggest names first, with Korea time and session. Filter by group: big tech, semiconductors, software, memory, healthcare, space
get_earnings_call_summaryThe latest earnings call in a few lines: one-line takeaway, positives, concerns, and up to three management quotes
search_stocksTicker lookup by name, including Korean names and nicknames (엔비디아 → NVDA, 구글 → GOOGL)

The next-day move is measured from the right session: same-day close for reports before the open, next trading day for reports after the close.

Every result links to the stock's afterns page as the source. Historical data only; it does not predict prices.

Try asking

  • "How did Nvidia's stock move after its recent earnings?"
  • "What big tech earnings are coming up next week?"
  • "Summarize Microsoft's latest earnings call."
  • "엔비디아 실적 발표 언제야? 한국시간으로"
