Edgar MCP Server

SEC EDGAR MCP Server 🏛️

U.S. SEC filings and financial data for Claude Desktop and any MCP-compatible client, powered by SEC EDGAR. Search companies, pull filings (10-K, 10-Q, 8-K, Form 4, ...), read XBRL financials, and full-text search across all filings — all from natural language. No API key required.

npm package: edgar-mcp  ·  GitHub repo: danishashko/edgar-mcp.

🎯 What You Get

• 🔎 Company lookup by name or ticker → CIK
• 🗂️ Recent filings (any form type) with direct document links
• 📄 Latest filing of a type (newest 10-K / 10-Q / 8-K) in one call
• 💰 Financial highlights (revenue, net income, assets, equity, EPS) from XBRL
• 📈 Concept history — any GAAP line item over time
• 🔬 Full-text search across the last ~10 years of filings

Every tool returns human-readable markdown by default, or structured JSON on request (response_format: "json"). Lightweight (Python standard library + mcp only), no API key, retries on rate limits.

🚀 Quick Start

Add this to your Claude Desktop config and restart Claude:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "edgar": {
      "command": "npx",
      "args": ["-y", "edgar-mcp"],
      "env": {
        "SEC_USER_AGENT": "your-app-name your@email.com"
      }
    }
  }
}

The SEC asks every API client to send a descriptive User-Agent with contact info. Set SEC_USER_AGENT to your own name/email (a default is provided so it works out of the box). On first launch the npx wrapper creates an isolated Python environment and installs the dependency (one-time, ~a minute). You need Python 3.10+ and Node.js 16+.

Prefer a global install?

npm install -g edgar-mcp

{
  "mcpServers": {
    "edgar": {
      "command": "edgar-mcp",
      "env": { "SEC_USER_AGENT": "your-app-name your@email.com" }
    }
  }
}

🔧 Available Tools

Every tool also accepts response_format ("markdown", the default, or "json"). identifier accepts a ticker, CIK, or company name.

Common XBRL concepts for get_concept: Revenues / RevenueFromContractWithCustomerExcludingAssessedTax, NetIncomeLoss, Assets, Liabilities, StockholdersEquity, EarningsPerShareDiluted.

💬 Example Prompts

Once the server is connected, just ask Claude:

• "What's Apple's latest 10-K?"
• "Show me Tesla's recent 8-K filings."
• "What are Microsoft's headline financials?"
• "Show me NVIDIA's net income over the last few years."
• "Which companies mention 'quantum computing' in their 10-Ks?"
• "Find the CIK for Berkshire Hathaway."

🐛 Troubleshooting

"SEC EDGAR is rate-limiting requests" EDGAR allows ~10 requests/second. The server retries automatically; wait a moment if it persists.

"Not found" Use search_company to confirm the exact ticker/CIK first.

"Command not found" / "Python not found" Ensure Python 3.10+ and Node.js 16+ are installed and on your PATH. On macOS/Linux, try python3.

Tools not showing up in Claude

1. Confirm the config file is valid JSON (no trailing commas).
2. Fully quit and reopen Claude Desktop.

Using a different model or provider (LiteLLM, OpenRouter, NVIDIA NIM, a local model) This server never talks to a model. Your client starts it as a local process and speaks JSON-RPC over stdin/stdout, so changing ANTHROPIC_BASE_URL or swapping the model behind your client has no effect on it. If tools stop firing after a switch like that, check two things: the model has to support function calling, and a proxy configured to drop unsupported parameters can silently strip your tool definitions, which produces no error at all. Run /mcp in your client (or claude mcp list) to confirm the server is connected before suspecting the server.

🛠️ Manual Installation (Alternative)

If you would rather run the Python file directly instead of via npx:

1. Download the server and install the dependency

pip install mcp

(or pip3 on macOS/Linux)

2. Point Claude Desktop at it

{
  "mcpServers": {
    "edgar": {
      "command": "python3",
      "args": ["/absolute/path/to/edgar_mcp.py"],
      "env": { "SEC_USER_AGENT": "your-app-name your@email.com" }
    }
  }
}

On Windows use "command": "python" and a path like "C:\\path\\to\\edgar_mcp.py".

3. Restart Claude Desktop.

🔒 Privacy & Rate Limits

• Uses the official SEC EDGAR APIs — public, no key.
• Requests go straight from your machine to the SEC. Nothing is stored or proxied.
• The SEC requires a descriptive User-Agent with contact info and limits ~10 requests/second.
• Intended for personal, educational, and research use.

📝 Notes

• identifier is flexible: ticker (AAPL), CIK (320193), or name (Apple).
• Financial data comes from XBRL, first required by the SEC in 2009, so history goes back that far for most filers.
• get_company_facts returns highlights; use get_concept for the full series of any one metric.
