Overview
ShareSeer MCP Server
A remote MCP server exposing SEC filings, insider transactions, and largest-trade data as six tools for Claude and other MCP assistants. Use when an assistant needs to answer questions about a company's SEC filings or market-wide insider trading activity.
What it does
ShareSeer MCP Server gives Claude and other MCP-compatible assistants access to SEC filings, insider transactions, and financial data through a hosted, remote MCP endpoint. It exposes six tools: get_company_filings and get_insider_transactions for a specific company, get_recent_filings and get_recent_insider_activity across all companies market-wide, and get_largest_daily_transactions/get_largest_weekly_transactions for the biggest insider trades over those windows.
When to use - and when NOT to
Use this connector when an assistant needs to answer questions about SEC filings or insider trading activity - "show me recent insider trading for Tesla," "who made the biggest stock purchases today," "what are the most recent 10-K filings," or "show me the largest insider selling activity this week." The free tier is deliberately limited: insider transaction results are capped at 3 per query, largest-transactions data only covers completed weeks (not the current one), and filings history goes back only 24 months with no pagination - so for any real trading or research workflow needing more than a handful of results, current-week data, or history older than two years, the Premium tier is necessary rather than optional.
Capabilities
Free accounts get 10 requests/hour and 50/day, 24 months of filings history, basic company info and filings, insider transactions limited to 3 results, insider data on a ~24-hour delay, and largest-transaction data limited to completed weeks, with community support via GitHub Issues. Premium ($49/month) raises limits to 100/hour and 1,000/day, extends filings history to 10 years, gives real-time (5-minute) insider data, removes the insider-transaction result cap, adds current-week plus historical largest-transaction data and pagination, and includes email support.
How to install
The recommended path is the remote MCP server - no local installation, always up to date, hosted by ShareSeer. In Claude Desktop, go to Search & Tools → Add Integrations → Add Integration URL and enter:
https://shareseer.com/mcp?api_key=YOUR_API_KEY_HERE
Get the API key (prefixed sk-shareseer-) by signing up free at shareseer.com/signup and viewing your profile page. If tools don't appear after adding the integration, verify the key is correct and active, then restart Claude Desktop.
Who it's for
Traders, investors, and researchers who want an AI assistant to surface SEC filings and insider-trading activity conversationally - checking a specific company's recent filings and insider transactions, or scanning the market for the largest daily or weekly insider trades - without manually searching EDGAR or a financial data terminal. Because the server is hosted remotely by ShareSeer rather than run locally, there is nothing to install or keep updated - the tradeoff is that usage is metered against the account's subscription tier, so heavier or more frequent querying should be matched to the rate limits (10/hour free, 100/hour Premium) rather than assumed unlimited. The project itself is MIT-licensed.
