Tools
| Tool | What it returns |
|---|---|
get_earnings_reactions | For 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_calendar | Upcoming 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_summary | The latest earnings call in a few lines: one-line takeaway, positives, concerns, and up to three management quotes |
search_stocks | Ticker 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.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
