fred-mcp
Enables browsing, searching, and retrieving FRED economic data (800k+ indicators) through LM Studio plugins or MCP, with units/frequency conversion. Supports natural language queries for series like GDP and UNRATE.
README
FRED MCP → LM Studio Plugin (Port)
原專案: https://github.com/stefanoamorelli/fred-mcp-server
本移植版將 3 大工具完整帶入 LM Studio Plugin 系統,程式碼精簡高效 (< 300 LOC 核心)。
功能對應
| 原 MCP Tool | LM Studio Plugin Tool | 說明 |
|---|---|---|
fred_browse |
fred_browse |
瀏覽 categories/releases/sources/category_series/release_series |
fred_search |
fred_search |
關鍵字 / tag 搜尋 80 萬+ 指標,找 GDP, UNRATE 等 ID |
fred_get_series |
fred_get_series |
取回時間序列觀測值,支援 units/frequency 轉換 |
架構
fred-mcp-lmstudio/
├── manifest.json # LM Studio 插件描述 (owner=local)
├── package.json
├── tsconfig.json
├── src/
│ ├── index.ts # main() 註冊 config + toolsProvider
│ ├── config.ts # globalConfig: fredApiKey, perChat: limit/sort
│ ├── fredClient.ts # 極簡 FRED API fetch wrapper (共用)
│ └── toolsProvider.ts # 3 tools 實作,<250 行
核心設計:
- fredClient.ts 單一 fetch 函式處理所有 FRED endpoint,自動加上
api_key&file_type=json,錯誤精簡拋出 - config 分離:API Key 放 Global (跨對話共用),limit/sort 放 Per-Chat
- toolsProvider 共用
getKey()+clean()去除空參數,避免冗長程式碼 - 觀測值只回傳最後 200 筆 + metadata,避免 LLM token 爆炸,仍保留 count/range
安裝 (LM Studio Plugin 模式 - 推薦)
前置
- LM Studio >= 0.3.17
lmsCLI 已在 PATH (LM Studio 附帶)- FRED API Key: https://fred.stlouisfed.org/docs/api/api_key.html
自動安裝
git clone https://github.com/stefanoamorelli/fred-mcp-server fred-mcp-lmstudio
cd fred-mcp-lmstudio
# 複製本移植的檔案覆蓋 (或直接用本資料夾)
npm install
npx tsc
# 複製到 LM Studio plugins 目錄
# Windows:
# mkdir "%USERPROFILE%\.lmstudio\extensions\plugins\lmstudio\fred-mcp-lmstudio"
# Linux/macOS:
mkdir -p ~/.lmstudio/extensions/plugins/lmstudio/fred-mcp-lmstudio
cp -r manifest.json package.json dist src ~/.lmstudio/extensions/plugins/lmstudio/fred-mcp-lmstudio/
# 啟動 dev 模式
cd ~/.lmstudio/extensions/plugins/lmstudio/fred-mcp-lmstudio
lms dev
在 LM Studio 設定 API Key
- 開 LM Studio → 右側 Program → Plugins → fred-mcp → Settings
- Global Config → FRED API Key 貼上
- 存檔,plugin 自動重載
使用
載入任意支援 tool calling 的模型 (Qwen2.5, Llama 3.1, GPT-OSS 等)
"幫我搜尋失業率相關指標,然後取 UNRATE 最近 2 年數據"
模型會自動呼叫 fred_search → fred_get_series。
安裝 (MCP Server 相容模式 - 給 LM Studio mcp.json)
如果你不想用 Plugin,也可當成純 MCP Server 給 LM Studio 使用 (LM Studio 原生支援 MCP)。
1. 編譯獨立 MCP Server
本移植已內含 src/mcpServer.ts 精簡版 MCP Server (std io + http 可選)。
npm install @modelcontextprotocol/sdk
# 已在 src/mcpServer.ts
npx tsc
2. 編輯 LM Studio mcp.json
Program → Install → Edit mcp.json
{
"mcpServers": {
"fred-mcp": {
"command": "node",
"args": ["/absolute/path/to/fred-mcp-lmstudio/dist/mcpServer.js"],
"env": {
"FRED_API_KEY": "YOUR_KEY_HERE"
}
}
}
}
或使用 http 傳輸:
{
"mcpServers": {
"fred-mcp": {
"url": "http://localhost:3000/mcp",
"headers": {}
}
}
}
# 啟動: PORT=3000 TRANSPORT=http node dist/mcpServer.js
儲存後 LM Studio 會自動載入 3 tools。
範例 Prompt
- "瀏覽 FRED 的 GDP 相關分類"
- "搜尋 CPI 相關 series,選最熱門的 5 個"
- "取 GDP (series_id=GDP) 2020-01-01 到現在,轉成年增率 pc1"
- "比較 UNRATE 和 CPIAUCSL 最近一年走勢"
