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.
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.
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.
