Signal8 MCP server
by signal8ai
Lets your AI pull SEC filing data, insider trades, dilution risk scores and stock screens for you.
This is a helper that connects your AI assistant to Signal8, a service that reads and organizes SEC filings and stock market data. Once it is set up, you can just ask questions in plain English about companies, insiders, ownership and dilution risk, and your AI will go fetch the numbers. It is handy for anyone who follows public companies, from analysts to curious investors.
What is an MCP server? The 30-second version
On its own, your AI can only chat with you using what it already learned. An MCP server is a small helper program that gives your AI a new skill or a connection to an outside service. This one connects your AI to Signal8, which holds SEC filing data, insider trades, ownership records and stock market information. So when you ask about a company, your AI can look it up there and bring the answer back to you.
What this MCP server does
You ask your AI a question, like what a company's dilution risk looks like or who has been buying its stock. Your AI passes that request to this helper, which talks to Signal8's data service. Signal8 looks through SEC filings, market data and ownership records, then sends the results back. Your AI turns those results into a plain answer, a list or a small table right in your chat. You never have to open a filing or a spreadsheet yourself.

Try asking your AI
- “What is Apple trading at right now?”
- “Show me the dilution risk score for a small biotech I follow”

- “What were the top gainers in the market today?”
What it gives back to you
You get back answers in your chat: numbers, short lists, small tables or short summaries. For example, a quote comes back as a price with the day's change, and a dilution check comes back as a score from 0 to 100 with a short breakdown. Insider or ownership questions come back as lists of names, dates and amounts. Screening questions come back as a list of matching tickers.
