🤖 Copilot Studio AI Agent Open Source Solutions

These Microsoft 365 open source solutions demonstrate how to design and deploy practical Copilot Studio agents grounded on SharePoint knowledge sources, connected to Power Automate workflows, and published to Microsoft Teams. Each agent targets a specific business scenario — replacing a manual process with an AI-driven conversational experience.

HR Employee Onboarding AI Agent — Copilot Studio Open Source Example

An open source Copilot Studio AI agent that replaces manual HR onboarding emails with a conversational Teams experience. New employees get instant answers to first-week questions, raise IT workstation requests, and complete policy acknowledgements — all through a single agent grounded on a SharePoint knowledge base and backed by Power Automate approval workflows. A practical starting point for any organisation looking to automate employee onboarding with Microsoft 365.

📂 SharePoint Online & SPFx Open Source Solutions

Open source SharePoint Framework (SPFx) components, permission governance tools, and modern intranet solutions. The governance tools are specifically built to support Microsoft 365 Copilot readiness — identifying oversharing, broken permission inheritance, and stale access grants before Copilot is deployed across a tenant.

SharePoint Copilot Readiness Scanner — SPFx Open Source Tool

An open source SPFx solution for Microsoft 365 Copilot readiness assessment. Scans SharePoint Online environments to surface governance gaps — overshared libraries, broken permission inheritance, and content issues — before Copilot is deployed. Microsoft 365 Copilot surfaces content users can already access, so oversharing that was invisible before becomes immediately discoverable once Copilot is enabled. This tool gives administrators the visibility to fix that before rollout.

SharePoint Permission Audit Report — Governance Open Source Solution

An open source SharePoint Online permission auditing solution that identifies broken inheritance, overshared document libraries, and stale access across a tenant. Designed for Microsoft 365 administrators running security reviews or preparing environments for Copilot deployment — where oversharing remediation is a required step before granting users access to Copilot.

Modern Employee Directory — SharePoint SPFx Open Source Component

An open source SharePoint Online people directory solution that extends the default Microsoft 365 people search with improved organisation visibility, profile presentation, and employee discovery. A reusable SPFx component for organisations building or modernising their Microsoft 365 intranet.

🏗️ Common Architecture Across These Microsoft 365 Open Source Solutions

Most Microsoft 365 open source solutions in this portfolio share a consistent layered architecture. The presentation layer uses Microsoft Teams, Power Apps, or Copilot Studio agents as the user-facing interface. The automation layer handles business logic through Power Automate cloud flows and approval workflows. The data layer sits in SharePoint Online or Dataverse, accessed where needed through Microsoft Graph. Everything runs on the Microsoft 365 platform, governed through Microsoft Entra ID and Power Platform environment controls.

Keeping solutions within the Microsoft ecosystem reduces integration complexity, simplifies governance, and makes Copilot readiness achievable — because the data, identity, and permission model is consistent across every layer.


❓ Frequently Asked Questions

What Microsoft 365 open source solutions are available here?

This portfolio includes 10+ Microsoft 365 open source solutions across four categories: Copilot Studio AI agents, Power Platform business applications, SharePoint Online governance tools, and SPFx components. All solutions are published on GitHub with full documentation covering the architecture, technology stack, and build approach — free to use, adapt, and build on.

What open source Copilot Studio agent examples are available?

There are two open source Copilot Studio agent examples: an HR employee onboarding agent that replaces manual email-based onboarding with a Teams AI assistant grounded on SharePoint, and a Microsoft 365 helpdesk agent that handles common employee support queries using SharePoint as the knowledge source. Both include Power Automate integration and are deployable to Microsoft Teams.

How does SharePoint oversharing affect Microsoft 365 Copilot?

Microsoft 365 Copilot surfaces content that users already have access to through existing SharePoint permissions. In most mature tenants, years of broad sharing — legacy group-wide access, broken permission inheritance, and forgotten sharing links — means Copilot can surface content that was never intended to be widely visible. The open source SharePoint governance tools in this portfolio are built specifically to identify and remediate those gaps before Copilot is deployed.

What is the difference between Power Apps canvas app and Code Apps?

Power Apps canvas apps are built using drag-and-drop controls — accessible to makers without a coding background. Power Apps Code Apps use React and TypeScript, giving professional developers full control over the UI and component architecture while staying within the Power Platform deployment and governance model. Both implementations of the asset management solution are available here as open source references, making it easy to compare the two approaches side by side.

Are these Microsoft 365 open source solutions production ready?

These solutions are shared as open source learning references and architectural starting points, not as fully supported commercial products. Each includes documentation covering the design decisions and build approach. Before deploying to production, review your organisation’s security requirements, Microsoft licensing obligations, governance policies, and any compliance requirements specific to your industry or region.

Who are these open source Microsoft 365 solutions designed for?

These projects are most useful for Microsoft 365 developers and solution architects, Power Platform makers and citizen developers, SharePoint administrators managing governance and Copilot readiness, IT teams evaluating Microsoft 365 automation patterns, and consultants or Microsoft partners building solutions for enterprise clients across Singapore and the Asia-Pacific region.
