What is the Lit Forge MCP MCP server?

Lit Forge MCP MCP server exists for a simple reason — assistants are far more useful when they can act on Lit Forge MCP directly instead of describing what you should do. MCP server (19 tools): NISA/iDeCo/retirement simulation, 28-indicator market snapshot, economic release calendars (BEA/NY Fed/FRB/BLS/JOLTS/DOL-ETA/S&P Global/Cabinet Office/BOJ), central bank speakers (Fed/BOJ/ECB, live), latest BLS macro.

What you get

Claude Desktop / Claude Code / Cursor など、MCP に対応した任意の AI クライアントで動作します。

What the assistant can call

Once Lit Forge MCP is connected, these are the calls the assistant has available:

  • simulate_nisa — 月の積立額・想定年利・年数から、月次複利で評価額・運用益・年次推移を試算
  • plan_retirement — 年齢・貯蓄・収入・希望生活費・リスク許容度・年金から、楽観/現実/悲観 3 シナリオで老後資金の充足度を診断 + 必要月額逆算
  • calculate_required_monthly — 目標金額・現在の貯蓄・年利・年数から、達成に必要な毎月の積立額を逆算
  • calculate_compound_interest — 元本(一括)と月次積立を月次複利で評価する汎用複利計算ツール

Setting it up

lit-forge-mcp on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Choosing this one

Plenty of planning and project tracking servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Lit Forge MCP's toolset — simulate_nisa, plan_retirement, calculate_required_monthly and 1 more — is a fair guide to whether it matches your workflow. It is maintained by noblabs; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Before you rely on it

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the lit forge mcp mcp server does with a few real requests.
