mcp-edgar 0.1.0

MCP server for clean, normalized SEC EDGAR, FRED, ETF and index data

EdgarMCP

An MCP server that gives AI agents clean, normalized access to financial data: company fundamentals and insider trades from SEC EDGAR, macro series from FRED, real-time quotes via the Tradernet WebSocket feed, ETF/fund holdings from SEC NPORT-P, look-through analytics, and index snapshots.

Raw sources (XBRL, bulky filing HTML, ownership XML) are expensive and error-prone for agents — they burn tokens and trip up on parsing. EdgarMCP returns agent-ready JSON.

Installation

pip install mcp-edgar

This installs the edgarmcp console script (a stdio MCP server).

Quick start

Add it to an MCP client. For Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "edgarmcp": {
      "command": "edgarmcp",
      "env": {
        "FRED_API_KEY": "your-free-fred-key",
        "OPENFIGI_API_KEY": "optional-openfigi-key"
      }
    }
  }
}

Both keys are optional: without FRED_API_KEY the FRED-backed tools degrade gracefully; without OPENFIGI_API_KEY holding resolution runs in anonymous mode.

Tools

Tool	Purpose
get_company_facts(ticker)	Normalized fundamentals (revenue, EPS, margins, debt)
get_financial_statement(ticker, statement, period)	Income/balance/cashflow as structured JSON
get_filings(ticker, form_type, limit)	Recent SEC filings (10-K/10-Q/8-K) with metadata and document URLs
parse_filing_section(url, section)	Extract a 10-K section (Risk Factors, MD&A) as clean text
get_insider_trades(ticker, limit)	Form 3/4/5 insider transactions (who, role, buy/sell, volume)
get_macro_series(series_id, start, end)	FRED macro series (rates, inflation, unemployment) with metadata
get_quote(ticker)	Real-time L1 quote (last/bid/ask/volume) via the Tradernet WebSocket feed
get_etf_holdings(ticker, limit)	ETF/fund holdings (top by weight) + AUM, NAV, asset/country mix from SEC NPORT-P
get_holdings_analysis(symbol, limit)	Look-through of an ETF/index: sector breakdown + weighted net-margin/ROE with coverage
get_index(index)	Index snapshot (S&P 500, NASDAQ-100, Dow, NASDAQ Composite): level from FRED, tracking ETF, holdings preview

Configuration

Variable	Description	Default
EDGAR_USER_AGENT	User-Agent for SEC requests	EdgarMCP/0.1 (contact: [e-mail])
EDGAR_RATE_LIMIT	Requests per second	10
EDGAR_CACHE_DIR	File cache directory	edgar_cache
FRED_API_KEY	Free FRED key for get_macro_series / index levels	—
OPENFIGI_API_KEY	Optional OpenFIGI key for higher CUSIP/ISIN rate limit	—

Variables are read from the environment; locally you can put them in a .env file.

Architecture

Three isolated layers: a platform-independent data layer (HTTP client with a host allowlist, ticker/name/CUSIP/ISIN resolution, XBRL normalizers, filing/ownership/NPORT-P parsers, FRED, the Tradernet WebSocket client, OpenFIGI identifier mapping, look-through and index analytics); a cache layer (aggressive caching of immutable filings and FIGI mappings; mutable FRED series are not cached); and a thin MCP layer. The data layer knows nothing about MCP and ports unchanged between a marketplace and self-hosting.

Security

• Outbound requests are restricted to an HTTPS host allowlist (SSRF defense), centralized across all sources (SEC, FRED, OpenFIGI).
• Ownership and NPORT XML is parsed with defusedxml (XXE / billion-laughs defense).
• Secrets (FRED / OpenFIGI keys) are redacted from error messages and never placed in URLs or cache keys.
• Real-time quotes come from Tradernet's public anonymous WebSocket feed (wss://wss.tradernet.com/); a dedicated client with a hardcoded URL.
• CUSIP/ISIN holding resolution goes through OpenFIGI (api.openfigi.com, allowlisted); on failure it falls back to name matching.

Data licenses

SEC EDGAR data is public domain, used with a descriptive User-Agent and the 10 req/s limit. FRED data is provided by the Federal Reserve Bank of St. Louis under its terms of use. Real-time quotes come from Tradernet's public anonymous WebSocket feed. CUSIP/ISIN → ticker mapping uses OpenFIGI (Bloomberg; free tier, 25 req/min anonymous, 250 req/min with a key).
