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.
ISO 20022 FI-to-FI credit-transfer generation + validation (pacs.008 FI-to-FI Customer Credit Transfer, pacs.004 Payment Return, pacs.002 Status Report). 15 tools across message-type + scheme discovery, JSON Schema + rail-usage validation, validated XML generation, XSD validation, inbound parsing, the November 2026 structured-address cliff toolkit (classify/validate/repair/batch), and legacy SWIFT MT103 → pacs.008 conversion. Built on the pacs008 library (100% branch coverage, Apache-2.0). Install pip install pacs008-mcp, run pacs008-mcp.
