lit-forge MCP server

lit-forge is a helper you add to your AI so it can do personal savings planning and market lookups for you. It is made with Japan in mind: Tsumitate NISA, iDeCo, retirement gaps, and the monthly amount you would need to save. It is handy if you are planning your own money and also like to keep an eye on markets and news.

What this MCP server does

You ask your AI a question, like how much to save each month or what markets did today. Your AI passes that to this helper program running on your computer. The helper does the math itself for savings questions, and for market questions it fetches data from public sources like Yahoo Finance, official economic calendars, and news feeds. Then it hands the results back to your AI, which explains them to you in the chat. Nothing is stored on a company server; it all runs locally on your machine.

Try asking your AI

• “I am 35, saving 30,000 yen a month, with 5 million yen saved now. I want to retire at 65 and live on 250,000 yen a month. Will I have enough?”
• “I want 20 million yen in 20 years. I have 5 million now and expect 4 percent a year. How much should I save each month?”
• “Summarise today's market in 28 indicators and show me the day-on-day changes as a table.”
• “When is the next US jobs report, and what were the latest CPI and PPI year-on-year figures?”

What it gives back to you

For savings questions you get numbers and a short breakdown: the final amount, the profit, and a year-by-year table, plus a monthly figure you would need to save. For market questions you get lists and tables, like 28 indicators with their day-on-day moves, or a stock's price and fundamentals. For calendar and news questions you get dated lists of upcoming events or recent headlines with sources. Everything shows up as normal text and tables in your chat.
