The Model Context Protocol (MCP), an open standard developed by Anthropic, enables LLMs to access external data and tools. A new public MCP server for tax data, hosted by 2Fin at taxmcp.ai2fin.com, allows users to query tax rates and estimates across 88 countries. This implementation emphasizes auditable responses by including source authority and verification dates with every query, preventing the common LLM failure mode of providing confident but unprovable information. AI

RANK_REASON The item describes a product/service that integrates an existing standard (MCP) with a specific domain (tax data), rather than a novel model release or core research.
