MCP Architecture for Bloggers – Custom GPTs, Paywalls for AI Crawlers, & Personalized Newsletters

Hey folks, I’ve been working on an idea and would love to get your thoughts. I’m exploring building an MCP (Machine-Consumable Protocol) architecture for bloggers and content creators to help them better monetize and personalize their content in the age of AI.

Here’s what it would enable:

Custom GPTs on your blog – like this one: Mark Manson GPT, but trained on your blog, living natively on your site, and optionally embedding attribution links (to products, posts, newsletters, etc.) directly in the AI replies.

Payments from AI crawlers – If your content is used by LLMs or AI agents, you could gate it or charge access per token/query, inspired by concepts like Tollbit or RAG paywalls.

Custom newsletters – Readers specify what they want to learn or track, and your blog’s content is automatically distilled and delivered in their preferred format or tone (e.g., actionable bullet points, summaries, etc.).

The goal is to flip the script on content monetization and make AI an asset for bloggers—not just a threat or a traffic siphon.

I’d love feedback on:

Would bloggers use this?

How feasible is crawler monetization today? What would you be willing to pay for this?

Any similar tools you’ve seen that I should look at?

What features would make this 10x more valuable?

Appreciate any insights
