SEC-MCP

MCP server for analyzing SEC filings (10-K, 10-Q, 8-K) with industry-aware financial extraction and BERT-based NLP.

Features

• Company Search — Look up companies by ticker or name via SEC EDGAR

• Standardized Financials — Industry-aware XBRL extraction with ~250 concept mappings across 5 industry classes (standard, bank, insurance, REIT, utility)

• Validation — Automatic sanity checks (revenue ≥ net income, accounting equation, segment vs total detection)

• Filing Access — Fetch filing text and specific sections (Risk Factors, MD&A, etc.)

• Sentiment Analysis — FinBERT financial sentiment (positive/negative/neutral)

• Summarization — BART-based hierarchical summarization for long filing sections

• Entity Extraction — NER for companies, people, locations + regex for monetary values, dates, percentages

NLP Analysis

How financials extraction works

Industry detection

The SIC code is used to classify a company into one of 5 industry classes:

XBRL concept dictionary

xbrl_mappings.py maps ~250 XBRL concepts to 20+ standardized metrics. Each metric has an ordered list of concepts to try — earlier entries are preferred. Some entries are marked aggregate=True (sum all matching, used for multi-component revenue like banks).

Validation rules

Every extraction runs these checks:

1. revenue ≥ net income (when both positive) — catches segment-only revenue

2. Assets = Liabilities + Equity (within 5%) — catches mismatched concepts

3. Revenue not null — warns if no concept matched

4. Bank segment check — flags if bank revenue < 80% of net income

5. Gross margin 0–100% — for standard companies

Warnings are returned in the validation array so the AI can explain or retry.

Usage

Run as MCP server (STDIO)

python -m sec_mcp.server

Using with your app (Cursor, Claude Desktop, etc.)

1. Configure MCP so your app starts the SEC-MCP server (see below).

2. Set EDGAR_IDENTITY in .env or in the MCP server env.

3. The AI chooses the right tool per request:

   • "Apple's financials" → get_financials("AAPL")

   • "Compare AAPL vs MSFT vs GOOGL" → compare_companies(["AAPL","MSFT","GOOGL"])

   • "Morgan Stanley income statement" → get_income_statement("MS")

   • "What are Apple's risk factors?" → get_filing_text with section='risk factors'
