Use RegNewsWire your way

Read company updates on the web, save an email stream, or research with your agent. Create a Free account with an email code. No card required.

Website and email

  1. Sign in with your email and enter the six-digit code from your inbox.
  2. Find a company or topic, choose the content you want, and read the matching updates.
  3. Save your filters as a saved view. Add companies to a watchlist when you want a reusable company basket.
  4. For email, enable delivery in the saved view and choose the cadence and timezone. Email requires paid or complimentary access; saving a view leaves email off by default.

Give these instructions to your coding agent

Connect RegNewsWire using its native remote MCP setup. Read https://www.regnewswire.com/llms.txt and https://www.regnewswire.com/connect, add https://www.regnewswire.com/mcp, and let me complete browser sign-in and consent. Then check my usage and find one recent company update.

Native MCP works without an additional helper or the optional agent skill.

Try your first research request

Check my RegNewsWire usage, then find recent news and earnings updates for Microsoft. Include dates and source links.

You can also ask for a watchlist or a saved view. Ask explicitly to enable email, with your desired cadence and timezone. ChatGPT push notifications are not available.
