Key takeaways

The short version.

  • SEC Stock Signals reads new 8-K and Form 4 filings from SEC EDGAR for the tickers you name, gives a reason for each flag and links the filing.
  • Perplexity answers with citations, which suits the second step: finding the news and commentary around a filing you have already read.
  • Perplexity's help center describes custom remote connectors that take an HTTPS MCP address, so you can try adding the app yourself if your account allows it.
  • The help page does not say which plans include custom connectors, and members of an organization need an admin to allow them, so check your own account.
  • The app reports filings. It never says buy, sell or hold, and a search of coverage is not a forecast of what a stock will do.

Who it is for

Who is this pairing for?

  • It is for people who follow a few public companies and want a filing to hold up against the outside world before they form a view:…

  • SEC Stock Signals watches EDGAR for new 8-K and Form 4 filings on the tickers you name.

  • One tells you what was filed and why it may deserve attention.

It is for people who follow a few public companies and want a filing to hold up against the outside world before they form a view: individual investors, finance students, newsletter writers, journalists and employees who hold company shares.

SEC Stock Signals watches EDGAR for new 8-K and Form 4 filings on the tickers you name. An 8-K is the form a company files when something material happens. A Form 4 reports a purchase or sale by an insider. Perplexity is an AI answer engine that cites the pages it read.

One tells you what was filed and why it may deserve attention. The other helps you find what has been written about it. This is not an official integration, and AgentStructure has no partnership with Perplexity.

Use cases

4 ways people use SEC Stock Signals + Perplexity.

  1. Filing, then press

    1. Open the filing first, then search for what was reported

    Start with the app: which recent 8-Ks on my list matter, and why? Each result carries a reason and a link to the original on EDGAR, so the filing itself is always one click away.

    Then ask Perplexity what news outlets and analysts have written about that company this week. Because it cites its sources, you can tell a report that quotes the filing from one that only repeats a headline. Treat the coverage as leads to read.

  2. Item 5.02

    2. Check how a CEO or CFO change was described

    The app reads the Item 5.02 text of 8-Ks to separate CEO and CFO changes from routine officer news, and calls them out in its attention ranking.

    Once you have read the filing, ask Perplexity how the change was reported and whether a successor or reason has been given elsewhere. If the coverage says something the filing does not, the sources let you see where it came from.

  3. Reaction check

    3. Look at a market reaction without treating it as an answer

    A natural follow-up is whether the stock moved after the news. Perplexity can find articles that describe the move and link to them. That is a sourced picture of what was reported, not a measure of cause.

    For context that is not anecdotal, the app offers event-study statistics built from 2016 to 2024 filings and tested on a frozen 2025 holdout, comparing the next 20 trading days with the S&P 500. These are historical averages. They are not predictions, and neither tool tells you what to do.

  4. Watchlist

    4. Keep your own list and re-run it

    The app has no accounts and keeps no watchlist on its server, so your assistant holds the tickers and sends them with each request. Ask for what is new on the list whenever you like, then follow up in the same thread with a sourced question about the one filing that stands out.

    Ticker and watchlist lookups are Premium tools. The event-study tools and filings since a date you choose are free.

How to

How do I connect SEC Stock Signals to Perplexity?

  1. Step 1

    Copy the app's remote MCP address from [secstocksignals.com](https://secstocksignals.com): https://secstocksignals.com/mcp. The site says it needs no sign-up form.

  2. Step 2

    In Perplexity, open Plugins, or Customize and then Connectors. Per its [help center](https://www.perplexity.ai/help-center/en/articles/13915507-adding-custom-remote-connectors), choose Add custom, then Connector, then Add MCP connector, and select Remote.

  3. Step 3

    Enter a name and the address above. It must use HTTPS. Pick the authentication method the app's site asks for, tick the acknowledgement box and add it.

  4. Step 4

    Click the connector card to authenticate and enable it, then ask what is new for your tickers. Open the sources before you rely on any answer.

Perplexity's help page does not say which plans can add custom connectors. Organization members need an admin to allow it, and the page warns that Perplexity cannot verify third-party servers. If you cannot add it, use the app through another assistant that accepts a remote MCP connector, then paste the EDGAR links into Perplexity. SEC Stock Signals is not listed in Perplexity's directory or built into it.

FAQ

Frequently asked questions.

Is SEC Stock Signals an official Perplexity integration?

No. There is no partnership, listing or built-in integration. Perplexity describes custom remote connectors, and you add the app's address yourself if your account allows it.

Does it tell me to buy or sell?

No. It reports filings and never says buy, sell or hold. Its site states that it is not investment advice and that historical averages are not predictions. Perplexity's answers are information to check, not instructions.

Will it send me an alert when a filing lands?

Not automatically today. The site says automatic alerts are being tested and are not open for sign-up. Today you ask, and the assistant checks EDGAR live.

Where does the data come from?

Live 8-K and Form 4 data comes from SEC EDGAR, and each result links back to it. Historical figures come from the app's event study of 2016 to 2024 filings. Anything Perplexity adds comes from the pages it cites.

What does it cost?

The app is free during the beta. Event-study verdicts, integrity checks and filings since a date you choose are free. Ticker and watchlist lookups are Premium tools, and the site describes how they are billed.
