closegate is an open-source policy gate, audit log, and human-in-the-loop approval framework for finance AI agents. SOX-grade SoD, materiality routing, and tamper-evident audit logging — shipped as a Python library, an MCP server, and a Docker image.https://closegate.neullabs.com/en-usAstrohttps://closegate.neullabs.com/blog/fx-rates-intercompany-matching-multi-entity-ai/https://closegate.neullabs.com/blog/fx-rates-intercompany-matching-multi-entity-ai/Multi-entity teams need defensible FX rates per transaction date and reliable intercompany clearing across entities.
