Side-by-side comparison of two Model Context Protocol servers — install paths, tools, quality signals, and directory engagement so you can pick the right one for Claude, Cursor, and other MCP clients.
MCP server for the FLOX trading systems framework. 30 tools to run backtests, scaffold strategies, validate for lookahead bias, place orders, query PnL via Claude/Cursor. C++23 core with Python/Node/Codon/QuickJS strategy bindings. Same code from backtest to live (CcxtBroker or native connectors). Install: pip install flox-mcp.
Tenant-bound MCP server for agent spend authorization, policy guardrails, evidence, escrow settlement, and portable receipts. Sandbox bootstrap, spend intents, and completion validation for Cursor and Claude Code. TypeScript: npx -p @paybond/kit paybond login then npx -y -p @paybond/kit paybond-mcp-server. Python: pip install paybond-kit then paybond-kit-login and paybond-mcp-server. Docs.
