Provides realistic paper trading capabilities through Paper Invest's API, enabling AI assistants to execute trades, manage portfolios, and analyze markets with authentic market simulation including NBBO matching, slippage, partial fills, and broker-specific rules. Built by Paper Invest, Inc. using TypeScript and the Model Context Protocol SDK, the implementation offers 23 tools across account management, portfolio operations, trading execution, market data retrieval, position tracking, and margin trading functionality. Features JWT authentication with token caching, support for multiple portfolio types (cash, margin, IRA), comprehensive order types (market, limit, stop, trailing, bracket), and emulation of 22 different broker platforms with their exact trading restrictions, making it valuable for traders practicing strategies in realistic market conditions, developers building AI-powered trading applications, and financial educators teaching market mechanics through hands-on simulation.
