What is the Kabu MCP MCP server?

Kabu MCP MCP server exists for a simple reason — assistants are far more useful when they can act on Kabu MCP directly instead of describing what you should do. Japanese & Global Stock Market MCP Server for Claude, Cursor, VS Code.

What you get

Real-time quotes, technical analysis, market screening — all from your AI agent.

What the assistant can call

Once Kabu MCP is connected, these are the calls the assistant has available:

  • get_quote — Real-time stock prices (JPX, NYSE, NASDAQ, crypto)
  • search_stocks — Find any stock by name or keyword (日本語 OK)
  • get_chart — Historical OHLCV candlestick data
  • technical_analysis — RSI, SMA (5/20/50) with auto buy/sell signals
  • multi_quote — Batch quotes for portfolio monitoring
  • market_screener — Japan, US, and crypto market overview

Configuration and credentials

You will need one environment variable: KABU_MCP_LICENSE_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Setting it up

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.

Choosing this one

Among the monitoring and observability options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Kabu MCP's toolset — get_quote, search_stocks, get_chart and 3 more — is a fair guide to whether it matches your workflow. It is maintained by kame6493-del; 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.

Before you rely on it

  • 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.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the kabu mcp mcp server does with a few real requests.
