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 codespar 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

Lets an assistant read Foxbit crypto market data and manage a Foxbit account, including placing orders and moving funds.

What you can do: Connects to the Foxbit Brazilian cryptocurrency exchange through 21 tools. Public data tools cover markets, currencies, tickers, order books, recent trades and OHLC candles. Private tools read balances, orders, trades and deposits/withdrawals, and can create or cancel orders, create Pix BRL deposits and withdrawals, and send crypto withdrawals to an external wallet address.
When to use it: Use it when an assistant should monitor Foxbit markets or operate a Foxbit account: checking prices and order books, reviewing balances and order history, placing or cancelling orders, or handling Pix and crypto transfers. It is aimed at traders and merchants who already hold a Foxbit account.
Requirements: Runs locally as an npm package via npx, so Node.js is needed. Requires a Foxbit account with API credentials supplied as the environment variables FOXBIT_API_KEY and FOXBIT_API_SECRET. Network access to the Foxbit REST API is required. Desktop clients only.

Before you install

The API credentials grant full account access, including trading and withdrawals, so store them carefully. Tools can create and cancel orders, create Pix deposits and withdrawals, and send crypto to an external address; these move real money and are hard to reverse. Confirm amounts, addresses and Pix keys before approving any action.
