MarketStackMCP

For members

UseIt

Plug live feeds of specialist Substack authors into your model. Ask ChatGPT or Claude what the writers on MarketStack’s StackMaps have published, and get the author, title, link and exact time back. It lists; it never summarises or ranks.

Each post

Author, publication, title, subtitle, direct link, free or paid, exact time.

Window

Last 24 hours, or any range up to 14 days. Feeds checked about hourly.

Paid posts

Linked, not reproduced. Reading one needs that writer’s subscription.

Try asking

• “What has been published in the last 24 hours?”
• “What has been written about Micron this week? Author, title and link for each.”

Connect it
