Market Brief

MarketBrief MCP server License: MIT Python 3.11+

Turn 40+ data sources into a daily Wall Street-style market briefing — delivered to your Telegram, automatically.

MarketBrief is an open-source framework that fetches real-time market data, aggregates news from 40+ RSS feeds, and uses Claude AI to generate structured analyst-grade reports. Think of it as your personal Bloomberg terminal distilled into a daily briefing.

Every morning at 7:00 AM, you wake up to this in Telegram:

  "Rates rise, equities capsize"

  TODAY'S FOCUS:
  - CPI 08:30 ET — beat eases Fed, miss reprices June cut
  - Gold $3,100 support — break below = safe-haven bid fading
  - Trump tariff speech 14:00 ET — new China tariffs trigger risk-off

  4 analyst-grade issues with source citations...
  Positioning table (OW/UW/MW)...
  Categorized news digest with 30+ items...
  Economic calendar with 10+ events...

---

What Problem Does This Solve?

If you're a retail investor, crypto trader, or market enthusiast, you probably:

• Check 5-10 websites every morning for market updates
• Miss important economic data releases
• Lack a systematic way to connect dots across asset classes
• Wish you had an analyst writing you a daily briefing

MarketBrief automates all of this. It pulls data from official sources (Fed, SEC, FRED, ECB), market data providers (Yahoo Finance, CoinGecko), and 40+ news feeds — then uses Claude AI to synthesize everything into a structured briefing with specific price levels, source citations, and actionable positioning.

No AI key? No problem. Without ANTHROPIC_API_KEY, MarketBrief still outputs a complete data-only report: market snapshot, news feed, economic calendar — just without the AI commentary.

Edit .env with your API keys:

# Required for AI analysis (skip for data-only mode)
ANTHROPIC_API_KEY="sk-ant-your-key-here"

# Optional — enhances data coverage
FRED_API_KEY="your-fred-key"              # Free at https://fred.stlouisfed.org/docs/api/api_key.html
SOSOVALUE_API_KEY="your-sosovalue-key"    # ETF flow data

# Optional — delivery channels
TELEGRAM_BOT_TOKEN="your-bot-token"       # Create at https://t.me/BotFather
TELEGRAM_CHAT_ID="your-chat-id"

3. Run

# Data-only mode (no AI key needed, free)
marketbrief generate --no-ai

# Full AI-powered report
marketbrief generate --output json

# Fetch specific data
marketbrief fetch market      # Live prices: equities, FX, commodities, crypto

What You Can Customize

This is a template framework, not a finished product. Everything is designed to be modified:

Assets & Portfolio (config/portfolio.json)

Track whatever you care about. The default is US-focused, but you can:

{
  "holdings": [
    {"name": "Nikkei 225 ETF", "ticker": "EWJ", "category": "Japan Equities"},
    {"name": "Copper Futures", "ticker": "HG=F", "category": "Industrial Metals"},
    {"name": "Bitcoin", "ticker": "BTC-USD", "category": "Crypto"}
  ],
  "interest_areas": ["Semiconductors", "Uranium", "Japan"],
  "focus_regions": ["Japan", "US", "EU"]
}

Dashboard (config/dashboard.json)

Add or remove any asset that Yahoo Finance supports:

{
  "equities": [
    {"label": "Nikkei 225", "yf": "^N225"},
    {"label": "FTSE 100",  "yf": "^FTSE"},
    {"label": "DAX",       "yf": "^GDAXI"}
  ],
  "crypto_ids": ["bitcoin", "ethereum", "solana", "dogecoin"]
}

News Sources (config/feeds.json)

Add any RSS feed. Organize by category for smart filtering:

{
  "feeds": [
    {"name": "my_niche_blog", "category": "research", "url": "https://example.com/feed.xml"},
    {"name": "industry_news", "category": "markets",  "url": "https://industry.com/rss"}
  ]
}

Categories matter: government and geopolitics feeds are never truncated. macro and ai_tech feeds get a 7-day lookback (vs 36 hours for news).

AI Analysis Style (config/prompts/)

The Claude prompts are fully editable. You can:

• Change the output language (English, Chinese, or mixed)
• Adjust the number of analysis issues (default: 4)
• Modify the analyst voice (assertive sell-side vs neutral)
• Add custom analysis frameworks
• Change the positioning stance options

Use Cases & Ideas

MarketBrief is a starting point. Here's what you could build with it:

Use Case	How
Personal daily briefing	Configure your portfolio + Telegram, set up GitHub Actions cron
Crypto-focused tracker	Remove equities, add 20 crypto feeds, track DeFi protocols
Macro research assistant	Heavy on FRED + Fed + Treasury feeds, focus on rates/FX
Team morning standup	Push to a shared Telegram channel or Feishu group
AI agent data source	Use the MCP Server to give any AI assistant live market data
Trading signal pipeline	Add your own scoring logic to the news/calendar fetchers
Multi-language briefing	Change OUTPUT_LANGUAGE in the prompt to Chinese/Japanese
Earnings season tracker	Add earnings-focused RSS feeds, customize calendar filtering

---

MCP Server

MarketBrief can run as an MCP server, letting any AI assistant (Claude Desktop, Claude Code, etc.) call market data tools directly.

pip install marketbrief[mcp]
python -m marketbrief.mcp_server

Add to your Claude Desktop config (claude_desktop_config.json):

{
  "mcpServers": {
    "marketbrief": {
      "command": "python",
      "args": ["-m", "marketbrief.mcp_server"],
      "env": {"FRED_API_KEY": "your-key"}
    }
  }
}

7 Available Tools

Tool	What It Does	Needs AI Key
generate_report	Full AI-powered briefing pipeline	Yes
fetch_market_data	Equities, commodities, FX, rates, crypto snapshot	No
fetch_news	Aggregate 40+ RSS feeds with deduplication	No
fetch_calendar	Economic calendar (Forex Factory + MyFXBook)	No
analyze_regime	Macro regime detection (yield curve, credit, rotation)	No
analyze_breadth	Market breadth signals (advance/decline, MA crossovers)	No
fetch_etf_flows	BTC/ETH spot ETF daily flows and AUM	No

Most tools work without any API key — only generate_report needs Anthropic.

---

Automated Delivery (GitHub Actions)

Run MarketBrief on a schedule — no server needed:

1. Copy the workflow template:

   mkdir -p .github/workflows
   cp workflows/morning_report.yml.template .github/workflows/morning_report.yml
   

2. Add secrets in your GitHub repo (Settings → Secrets → Actions):

   • ANTHROPIC_API_KEY
