Is there a production-ready Java/Spring Boot MCP server template with OAuth 2.0 + PKCE?

Chetan Lohkare — Wed, 15 Apr 2026 14:42:14 +0000

I've built a remote MCP server in production (Spring Boot + OAuth 2.0 + PKCE + RFC 8414 discovery + tool access control) and I'm thinking of open sourcing it as a starter template.
Everything I've found is either Node.js, Python, or only covers the basic stdio transport with no auth. Is this something Java devs are actually struggling with? Would a Spring Boot starter with auth baked in be useful to you?

Open to feedback and suggestions.

AI Marketing OS built on Notion MCP

This is a submission for the Notion MCP Challenge

What I Built

I built an AI-powered Marketing and Content Operating System using Notion as the core system layer.

The system automates the entire workflow from idea to content generation. A user adds a raw idea in a Notion database, and an AI agent processes it to generate structured content automatically. The generated content is then stored in another database and linked back to the original idea, while updating its status to prevent reprocessing.

This creates a complete automated loop:
Idea → AI Processing → Content Creation → Storage → Status Update

The goal was to transform Notion from a passive workspace into an active execution system.

Turn ideas into high quality content automatically using AI agents + Notion as a brain.

🚀 Notion Marketing OS (AI Content System) Turn raw ideas into high-quality, multi-platform content using AI agents powered by Notion.

🧠 Overview Notion Marketing OS is an AI-powered workflow system that transforms unstructured ideas into structured, publish-ready content.

It combines:

Notion as a central knowledge base

AI agents (Claude) for content generation

A lightweight automation pipeline

The system eliminates the friction between thinking and publishing.

✨ Features 🧩 Convert ideas into structured content

✍️ Generate:

Instagram Reel scripts

LinkedIn posts

Twitter threads

🔄 Repurpose one idea across multiple platforms

🧠 Use Notion as a persistent memory layer

⚡ Automatically process new ideas

🔁 Write generated content back into Notion

🏗️ How It Works Idea (Notion) → AI Processing → Multi-format Content → Saved to Notion Flow Add a raw idea in Notion

The system detects new ideas

AI generates structured content

Output is stored back in Notion

Idea is marked…

How I Used Notion MCP

Notion is used as the central system to manage state, data, and workflow.
Ideas Database acts as the input layer where raw ideas are stored with a status field controlling execution.
The AI agent fetches entries with status "new" using the Notion API.
The agent processes each idea and generates structured content.
Content is stored in a separate Content database as new pages.
A relation field links generated content back to the original idea.
The system updates the idea’s status to "processed" after execution.
This setup uses Notion as a structured backend that enables:
State management through database properties
Workflow control through status fields
Data relationships between ideas and generated content
It effectively turns Notion into a programmable system where AI agents can read, act, and update data in a continuous loop.

Future Scope

Extend content generation to multiple platforms such as Twitter threads, LinkedIn posts, and short-form video scripts
Add a scheduling and publishing layer to automatically post content across platforms
Introduce a feedback loop by tracking engagement metrics and improving future outputs
Implement content scoring and ranking to prioritize high-performing ideas
Enable team collaboration with approval workflows inside Notion
Integrate external tools like social media APIs and analytics platforms
Add support for multiple AI agents handling different tasks (research, writing, editing)
Build a no-code trigger system inside Notion using buttons or automations

False alarm, everyone!

That moment when you think you’ve deleted critical code months ago… only to find out today it was actually just as unused as you thought.😅

What skills will be essential for professionals to thrive in an AI-driven world?

Chetan Lohkare — Tue, 06 Aug 2024 07:25:30 +0000

As a developer, the ability to debug AI-written code will be a crucial skill. AI can help write small code parts, but understanding the underlying logic of how things work is essential. Thoughts?
