Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account mrfentmen for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

An MCP server for the BitFlyer Japan crypto exchange that lets an assistant look up tickers, order books and markets.

What you can do: Look up ticker prices on the BitFlyer Japan crypto exchange. List the available trading markets and their details. Read order book depth, including buy and sell entries.
When to use it: Add it when an assistant should look up live BitFlyer Japan market prices, the list of markets, or order book depth. It is a read-only lookup tool, not for placing orders or account access.
Requirements: Runs as a local process from the npm package bitflyer-mcp over stdio, so Node.js is needed; desktop only. No API key is required, but network access to BitFlyer's public API is.

Before you install

It exposes public market data only and declares no authentication. Data comes from a third-party exchange, so accuracy and freshness depend on that service. The server itself does not place orders or move funds, but confirm the actual tool list before use.

Installation

In SourceWeft

Open Bitflyer Mcp in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.
