What I Built

The Jesse System AI Brain β€” a fully connected personal and business productivity system powered by Notion MCP and Claude AI.

The Jesse System is a small business automation consulting service that helps small business owners stop doing repetitive tasks manually. Today I built the entire infrastructure for it in a single session using Notion MCP as the backbone.

Here's what the system includes:

  • A structured Notion workspace with five interconnected sections: AI Conversations, Personal To-Dos, Market Research, Game Project, and Small Business
  • Claude connected to Notion via MCP β€” reading, writing, updating, and logging entries in real time through natural language
  • A live business website deployed at dulcet-churros-460036.netlify.app with an interactive Zapier explainer, pricing, and contact form
  • A real-time AI conversation logger β€” so nothing important discussed with any AI tool ever gets lost again
  • A business model built and documented inside Notion β€” with real 2026 market pricing data
  • A game concept developed and stored β€” Nurses vs. Zombies, a sci-fi comedy FPS ("Doom meets Scrubs")

The core idea: Notion becomes the brain that any AI can read from and write to β€” solving the real problem of losing context between AI sessions.

Claude Desktop was connected to Notion MCP using this config at %APPDATA%\Claude\claude_desktop_config.json:

{
  "mcpServers": {
    "notionMCP": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.notion.com/mcp"]
    }
  }
}

The Claude.ai web connector was also used via https://mcp.notion.com/mcp with full OAuth authorization and read/write access.

How I Used Notion MCP

Notion MCP was the core of everything built today. Here's exactly what it did:

Real-time read/write via natural language β€” Claude read and wrote to Notion pages throughout the entire session without me touching Notion manually. I'd say "log today's session" and it appeared in my AI Conversations database instantly.

Living business documentation β€” The Jesse System's business description, pricing model, market research, and game concept were all built and stored directly into Notion through Claude. The workspace is now a working knowledge base any AI can reference.

Context persistence across sessions β€” The biggest problem I was solving for myself: I kept forgetting what I'd told which AI. Notion MCP means Claude can now look at my workspace and immediately know my projects, my business, and my history β€” no re-explaining required.

To-do management β€” Tasks were added to my Personal To-Dos page mid-conversation without interrupting the flow of work.

The integration dropped near the deadline due to a session conflict, but was fully functional throughout development with 13 Notion tools active including search, fetch, create-page, update-page, and move-pages.

"Someone running a business isn't looking for showmanship. They're looking for simplicity and clarity." β€” That's the philosophy behind The Jesse System, and behind using Notion MCP as the foundation.
