For AI agents
PreBell runs a read-only MCP (Model Context Protocol) server. Your own AI agent can use it to read the earnings calendar, the earnings checks (each figure with the sentence it came from, plus the SEC filing link) and the latest brief or recap. There is no sign-in: everything it serves is already public on this site.

In Claude Code, run:

Tools
earnings_calendar: Who reports earnings on which days and whether each date is confirmed, with the day's economic events (Fed decisions, jobs report, CPI).earnings_report: The newest earnings check PreBell has published for one company: the key figures, each with the press-release sentence it came from, and links to the check, the SEC filing and the press release. Without a check, it says whether the company has reported, or its next date on the calendar.latest_brief: The newest premarket brief or after-close recap: index futures or closes, the biggest movers with the published reason, and, in the premarket brief, the day's events to watch.
Titles and summaries come in Chinese when the Chinese version is published, otherwise in English; quoted filing text, mover reasons and the guidance and highlight notes stay in English.
Things to ask your agent
- Who reports earnings this week?
- What did PreBell's latest earnings check on Apple show?
- What did this morning's brief say?
Limits
- The brief is a snapshot written at set times, not a live feed: the premarket brief comes out from 8:00 AM Eastern on trading days and is usually rebuilt after 8:35 with fresh prices and any 8:30 economic releases, and the after-close recap from 4:45 PM Eastern (1:45 PM on early-close days). Before today's brief is out, your agent gets the most recent one, with a note saying when the next is due.
- There are no live quotes: every price comes from a published brief or earnings check and carries its own time.
- Informational only: generated automatically from public data; not investment advice; not real-time.
