It is for people who follow a handful of public companies and do not want to read every SEC filing line by line: individual investors, analysts in training, finance students, journalists and anyone who holds shares in an employer.

SEC Stock Signals watches EDGAR for new 8-K and Form 4 filings for the tickers you name and flags the ones it judges worth a look, with the reason and a link. An 8-K is the form a company files when something material happens, such as a leadership change. A Form 4 reports a purchase or sale by an insider.

Claude is Anthropic's AI assistant, and it reads long text well. Together, the app answers which filing and why, and Claude helps you read it.

Use cases

4 ways people use SEC Stock Signals + Claude.

  1. Plain English

    1. Ask what changed in the newest 8-K

    Start with the question you would ask a colleague: which recent 8-Ks on my watchlist matter most, and why? The app ranks recent 8-Ks by attention and says why each one scored as it did. Claude then explains the top filing in plain language and points you to the original on EDGAR.

    Because every filing links back to EDGAR, you can check Claude's explanation against the source text. Treat the summary as a guide to where to look, not a replacement for the filing.

  2. Item 5.02

    2. Separate a CEO or CFO exit from routine news

    Many 8-Ks are routine. Some report that an officer is leaving. The app reads the Item 5.02 text to separate CEO and CFO exits from other changes, and calls them out in its attention ranking.

    Ask Claude to put that filing in context: what the filing actually says, what it leaves out, and what a careful reader would want to find out next, such as whether a successor is named. It explains the filing. It does not tell you what to do with your shares.

  3. Watchlist

    3. Scan a whole watchlist in one question

    Name your tickers and ask for a scan. The app has no account and does not keep your watchlist on its server, so the assistant holds the list and sends it along with each request. Claude can keep your tickers in the conversation and re-run the scan whenever you ask.

    Whole-watchlist scans and lookups for any SEC-registered ticker are Premium tools. The event-study tools and filings since a date you choose are free.

  4. Event study

    4. Add historical context before you form a view

    The app also offers event-study statistics built from 2016 to 2024 filings and tested on a frozen 2025 holdout. They compare the next 20 trading days with the S&P 500. You can ask, for example, how stocks did over the next 20 trading days after a restatement 8-K.

    Claude can lay the numbers out clearly and remind you of what they are: a historical average, not a prediction. The app itself says so.

How to

How do I connect SEC Stock Signals to Claude?

  1. Step 1

    Open the setup page on [secstocksignals.com](https://secstocksignals.com) and copy the app's remote MCP address, https://secstocksignals.com/mcp. The site says there is no API key and no sign-up form.

  2. Step 2

    In Claude, go to Customize, then Connectors, and choose to add a custom connector. Enter a name and that address, then review the authentication settings Claude detects.

  3. Step 3

    Finish adding it. On a Team or Enterprise plan an organization owner adds it first, then each member connects.

  4. Step 4

    Start a chat, name your tickers and ask what is new. Review the tool requests Claude shows before you approve them.

Custom connectors are described in Anthropic's help center and its connectors overview. Plans and menus can change, so follow those pages. SEC Stock Signals is not listed in Claude's directory or built into Claude.

FAQ

Frequently asked questions.

Is SEC Stock Signals an official Claude integration?

No. There is no partnership or built-in integration. Claude supports custom connectors through remote MCP, and you add the app's address yourself. The app is an AgentStructure.AI app.

Does it tell me to buy or sell?

No. It is retrieval only and never says buy, sell or hold. Its alerts rank attention, not direction, and the site marks everything as not investment advice. A historical average is not a prediction.

Does it send me alerts automatically?

Today you ask. The site says automatic watchlist alerts are being tested and are not open for sign-up yet, so the way to use it with Claude is to ask for what is new.

Where does the data come from?

Live filings and Form 4 counts come from SEC EDGAR, and every filing links back there. The historical figures come from the app's event study.

Does the app see my brokerage or my chats?

The site says it does not read a brokerage, email or calendar, and does not store a user identity or a server-side watchlist. Your assistant keeps the ticker list and sends it with each scan. Claude's own data handling is described by Anthropic.
