Binance Trading Agent Server

A safety-first Model Context Protocol (MCP) server that connects any LLM client (Claude, Cursor, custom agents) to the Binance Spot API — with a hard focus on guardrails, testnet-first development, and auditable order flow.

---

Phase 1 — Read-Only Tools

7 read-only MCP tools for reading market data and account info on Binance Spot Testnet.

Tool	Type	Input	Purpose
get_spot_price	public	symbol	price, 24h change, bid/ask, high/low, volume
get_klines	public	symbol, interval, limit	candlestick data
get_order_book	public	symbol, limit	order book depth
get_symbol_rules	public	symbol	minQty, stepSize, tickSize, minNotional
get_account_balances	private	hideZero	free/locked balances, canTrade
get_open_orders	private	symbol?	open orders
get_trade_history	private	symbol, limit	recent trades

Not in Phase 1: order placement/cancellation, futures, margin, OCO, websockets, autonomous actions.
