What is the Stock MCP server?

Most developer tooling work still happens through a UI a human drives. Stock MCP server moves it into the conversation instead. Explains why US stocks moved. AI analysis for 'why did Tesla drop?' queries. S&P 500/NASDAQ/Dow.

The short version

AI-powered analysis explaining why US stocks moved. Built by WTF Just Happened.

Built by WTF Just Happened - market intelligence for retail investors. We use AI to explain significant stock movements so you understand what's happening in your portfolio.

The tools it exposes

The server publishes 1 tool. What each one is for:

  • Summary — Concise explanation of what drove the move

Getting it running

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.

How it compares

Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Stock's toolset — Summary — is a fair guide to whether it matches your workflow. It is maintained by Pink707Legendary; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Things to watch

  • 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.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
