🎄 The Story

At the North Pole, Santa Claus faces an increasingly complex challenge: managing millions of letters, verifying toy availability, calculating delivery routes, preparing reindeer, and sending confirmations.

Even traditional magic isn’t enough anymore.

The solution: A sophisticated system of 9 specialized agents working in harmony within Copilot Studio, where each elf is an expert in their domain, connected to real enterprise systems: Dynamics 365 F&O, Dataverse, SharePoint, map web services, and a custom reindeer MCP.

This is Santa’s headquarters in 2025. 🚀

🛠️ Tutorial: How to Create an Elf in Copilot Studio

To understand how to build this multi-agent system, I’ll guide you through creating an individual elf. The process is the same for all, so once you master it, you’ll be able to replicate it.

Step 1: Create a New Agent in Copilot Studio

Agent creation in Copilot Studio
  1. Open Copilot Studio
  2. Go to Agents and click Create
  3. Select Create a custom agent
  4. Give it a name: “Letter Reading Elf”
  5. Add a description: “Specialized in reading and processing children’s letters”
  6. Click Create

Step 2: Configure the System (System Prompt)

In the Instructions section, within the system field, place:

You are Letter Reading Elf, specialized in reading and processing children's letters.

Your function is:
1. Search for letters in the knowledge base
2. Extract information about the child (name, wish list)
3. Return structured data

Always respond in Spanish. Be professional but friendly.

Step 3: Connect the Knowledge Base (Knowledge Base)

Knowledge configuration in Copilot Studio
  1. Go to Knowledge in the side panel
  2. Click Add knowledge
  3. Select File or folder
  4. Upload a folder with PDFs of letters
  5. Copilot Studio will automatically index the files

Note: Copilot Studio supports PDFs, Word, Excel, and SharePoint. In our case, we use PDFs of letters.

Step 4: Configure Tools (Tools/Connectors)

Tool configuration in Copilot Studio

For the agent to be useful, it needs external tools:

  1. Go to the Actions section
  2. Click Create new
  3. Connect with external APIs or MCPs:
    • Power Automate: To send email notifications
    • Dataverse: To query contacts
    • SharePoint: To access files
    • REST APIs: To connect ERP, Maps, etc.
    • Custom MCPs: For specialized integrations

Example for Letter Reading Elf:

  • Action 1: “Search Knowledge” (knowledge base search)
  • Action 2: “Extract Text from PDF” (text extraction)
  • Action 3: “Log to Database” (log the query)

Step 5: Configure Triggers

Trigger configuration in Copilot Studio

Define when and how your agent is activated:

  1. Go to the Triggers section
  2. Select the activation type:
    • Manual: The user calls it explicitly
    • Automatic: It runs when certain conditions are met
    • Scheduled: It runs at predefined times
  3. For Letter Reading Elf: “Activates when the user asks about letters”

Step 6: Define Specific Instructions

In the Instructions section, specify what the agent should do in natural language:

When you receive a request:
1. Search for the child's letter by name
2. Read the PDF content
3. Extract: name, gift list, special notes
4. Return in JSON format
5. Log the search

Step 7: Test the Agent

  1. Click Test
  2. Type: “What did Lucas ask for?”
  3. The agent should search the knowledge base and return the information
  4. Iterate and adjust the system prompt if needed

Step 8: Connect with the Coordinator

In the Coordinator Elf agent, connect all other agents as sub-agents:

Coordinator connected to all agents in Copilot Studio
  1. In Coordinator, go to the Agents tab
  2. Click + Add an agent
  3. Select each of the elves:
    • Letter Reading Elf
    • Stock Elf
    • Route Optimization Elf
    • Reindeer Preparing Elf
    • Gift Wrapping Elf
    • Sales Elf

📊 The 9 Elves of Headquarters

🧝 1. COORDINATOR ELF (The Operations Manager)

🎄 Conclusion

Santa’s Headquarters is a living example of how multi-agents can transform complex processes into simple experiences.

It’s not magic, it’s AI engineering.

Each elf is a specialist. Coordinator Elf orchestrates. Santa (the user) just says what they want. The rest happens automatically.

This is the future of business automation. 🚀✨
