Show HN: A free MCP server for facts LLMs get wrong (time zones, holidays, FX) (apistack.online)

A new initiative called the Model Context Protocol (MCP) introduces a free server designed to enhance the capabilities of large language models (LLMs) like Claude, ChatGPT, and Cursor. This server provides a suite of 16 specialized tools focused on questions that LLMs typically struggle to answer accurately from memory, such as current time in different time zones, holidays, exchange rates, VAT checks, and more. Users can access this service without registration, gaining 50 free calls per day, making it an accessible resource for developers looking to improve AI accuracy in real-world contexts. The introduction of the MCP server is significant as it enables AI agents to deliver precise answers by leveraging deterministic data sources rather than relying solely on their training. By integrating these tools, users can create lighter, more efficient AI applications that can handle complex inquiries seamlessly. This shift towards context-aware AI interactions not only improves user experience but also opens up new possibilities for developers looking to build sophisticated, data-driven AI solutions. The initiative marks a step forward in bridging AI technology with context-sensitive applications, positioning it to significantly enhance productivity in various sectors.
