Introduction 📣

SEC EDGAR MCP is an open-source MCP server that connects AI models to the rich dataset of SEC EDGAR filings. EDGAR (Electronic Data Gathering, Analysis, and Retrieval) is the U.S. SEC's primary system for companies to submit official filings. It contains millions of filings and "increases the efficiency, transparency, and fairness of the securities markets" by providing free public access to corporate financial information. This project makes that trove of public company data accessible to AI assistants (LLMs) for financial research, investment insights, and corporate transparency use cases.

Using the Model Context Protocol (MCP) – an open standard that "enables seamless integration between LLM applications and external data sources and tools" – the SEC EDGAR MCP server exposes a comprehensive set of tools for accessing SEC filing data. Under the hood, it leverages the EdgarTools Python library to fetch data from official SEC sources and performs direct XBRL parsing for exact financial precision. This means an AI agent can ask questions like "What's the latest 10-K filing for Apple?" or "Show me Tesla's exact revenue from their latest 10-K" and the MCP server will retrieve the answer directly from EDGAR's official data with complete accuracy and filing references.

Usage 🚀

Once the SEC EDGAR MCP server is running, you can connect to it with any MCP-compatible client (such as an AI assistant or the MCP CLI tool). The client will discover the available EDGAR tools and can invoke them to get real-time data from SEC filings. For example, an AI assistant could use this server to fetch a company's recent filings or query specific financial metrics without manual web searching.

Architecture 🏗️

The SEC EDGAR MCP server acts as a middleman between an AI (MCP client) and the SEC's EDGAR backend:

🔸 MCP Client: Could be an AI assistant (like Claude or other MCP-compatible tools) or any app that speaks the MCP protocol. The client sends JSON-RPC requests to invoke tools and receives JSON results.
🔸 MCP Server (SEC EDGAR MCP): This server defines comprehensive EDGAR tools and handles incoming requests. It features:
- Company Tools: CIK lookup, company information, and company facts
- Filing Tools: Recent filings, filing content, 8-K analysis, and section extraction
- Financial Tools: Financial statements with direct XBRL parsing for exact precision
- Insider Trading Tools: Form 3/4/5 analysis with detailed transaction data
🔸 EDGAR Data Sources: The server uses the edgartools Python library to access:
- SEC EDGAR REST API: Official SEC endpoint for company data and filing metadata
- Direct XBRL Parsing: Extracts financial data directly from SEC filings using regex patterns for exact numeric precision
- Filing Content: Downloads and parses complete SEC filing documents (.txt format)

Key Features:

Deterministic Responses: All tools include strict instructions to prevent AI hallucination and ensure responses are based only on SEC filing data
Exact Precision: Financial data maintains exact numeric precision (no rounding) as filed with the SEC
Filing References: Every response includes clickable SEC URLs for independent verification
Flexible XBRL Extraction: Uses pattern matching to find financial concepts without hardcoded mappings

How it works: The MCP client discovers available tools (company lookup, financial statements, insider transactions, etc.). When invoked, each tool fetches data from SEC sources, applies deterministic processing rules, and returns structured JSON with filing references. This ensures AI responses are accurate, verifiable, and based solely on official SEC data.
