What it does

Domain	Tools
SEC EDGAR	Income statement, balance sheet, cash flow, company profile — from live XBRL filings
Ratios	20+ ratios (ROE, ROIC, FCF margin, D/E, CCC, …) computed from the above
Reddit	Fetch posts + comment threads via public RSS; two-phase filter-then-fetch
Stocktwits	Fetch 30 latest messages with labeled sentiment; exponential backoff on rate limits

Skills in .claude/skills/ drive report generation — fixed-format markdown templates the agent fills with real numbers. No hallucinated data.

Usage — Claude Code / Claude Desktop plugin

The MCP server exposes the full bundle in one connection: 8 tools (raw data access) and 7 prompts (skills — invoke with a ticker to run a full structured report).

Install in Claude Code

From PyPI (recommended — no git clone needed):

pip install stock-analysis-mcp
claude mcp add stock-analysis -e REDDIT_USERNAME=your_username -- python -m stock_analysis.mcp_server

From source (development):

git clone https://github.com/SJDev2000/stock-analysis
cd stock-analysis
pip install -e .
claude mcp add stock-analysis -- stock-analysis-mcp

Once connected, skills appear as slash commands in any Claude Code session:

/stock-analysis:sentiment-analysis      → prompts for ticker, runs 11-section report
/stock-analysis:fundamental-analysis    → prompts for ticker, runs full EDGAR report
/stock-analysis:income-statement-analysis
/stock-analysis:balance-sheet-analysis
/stock-analysis:cash-flow-analysis
/stock-analysis:company-overview
/stock-analysis:stocktwits-sentiment

Tools are also directly available for raw data access:

mcp__stock-analysis__fetch_stocktwits_stream   ticker=AAPL
mcp__stock-analysis__analyze_income_statement  ticker=MSFT

Install in Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "stock-analysis": {
      "command": "python",
      "args": ["/absolute/path/to/stock-analysis/mcp_server.py"],
      "env": {
        "REDDIT_USERNAME": "your_username"
      }
    }
  }
}

Skills reference

Skills are markdown files in .claude/skills/ that drive structured report generation. They are loaded automatically by the Claude Agent SDK.

Skill	Invocation example
sentiment-analysis	"Run sentiment analysis on AAPL"
fundamental-analysis	"Run fundamental analysis on MSFT"
income-statement-analysis	"Income statement for GOOGL"
balance-sheet-analysis	"Balance sheet for TSLA"
cash-flow-analysis	"Cash flow analysis for NFLX"
company-overview	"Company overview for AMZN"

The sentiment-analysis skill runs with context: fork — it executes in an isolated sub-agent, keeping your main conversation thread clean. It fetches and scores both Reddit and Stocktwits, then produces an 11-section combined report with:

• Composite FSS (Reddit 60% + Stocktwits 40%)
• Per-platform signal distribution tables
• Cross-platform divergence analysis
• Labeled vs. inferred sentiment breakdown for Stocktwits
• Trading signal with risk flags

---

Sentiment scoring

Reddit scoring:

• Post: 3× weight | Long comment (≥50 words): 2× | Short comment: 1× | Reply: 0.5×
• Subreddit multiplier: major finance subs 1.0× | other finance 0.8× | non-finance 0.5×

Stocktwits scoring:

• Labeled Bullish → raw +1.5 | Bearish → raw −1.5
• Unlabeled → inferred from text on −2 to +2 scale; long messages 1.5× weight

Composite FSS = Reddit FSS × 0.6 + Stocktwits FSS × 0.4

Data sources

Source	Auth required	Notes
SEC EDGAR	No	XBRL filings via edgar-sec
Reddit	No	Public RSS feeds
Stocktwits	No	Public API — 200 req/hour limit

All data is sourced live. No fabricated numbers.
