mcp-market-server

MCP (Model Context Protocol) server exposing live crypto market data and a paper-trading engine as standardized tool calls — so any agent (Claude Code, custom multi-agent systems) can query Bybit and execute simulated trades.

Built for the Tower Research Capital AI/ML intern application: demonstrates MCP integration, agent tool-calling, risk controls, and production-style Python.

Setup

cd mcp-market-server
python -m venv .venv && .venv\Scripts\activate     # Windows
pip install -e ".[dev]"
cp .env.example .env                                # optional overrides
pytest                                              # run tests

Demo Prompts (after registering)

Fetch the last 100 hourly candles for BTCUSDT and summarize the trend.

Place a paper long of 0.01 BTCUSDT with a 2% stop loss and take profit at 3%.

Show my account, then flatten everything if unrealized PnL is worse than -$50.

Design Notes

  • Public endpoints only — no API keys, no real money. Paper engine fills market orders against live ticker price, limit orders when price touches.

  • SQLite for orders/positions/trades/audit — zero-dependency persistence, mirrors how quant desks log every decision.

  • Risk layer sits between tools and engine — same pattern as a real desk: strategy proposes, risk disposes.
