Using Tallyfy MCP Server with Microsoft Copilot Studio

MCP Client Compatibility

An MCP server can be used by any MCP client that supports it. Although you can use Tallyfy’s MCP server with common AI platforms like OpenAI, Claude or Microsoft Copilot Studio - the UI and ability to do useful work in real life is limited by many factors which are highlighted in this page. Tallyfy is developing its own fully-featured chat UI which will solve all the major problems of using MCP servers with mainstream text-chat AI providers. However, to start using MCP immediately - we recommend adding it to your AI subscription so that you can get the value and benefits immediately. You can additionally use the fully featured Tallyfy-specific AI interface when we launch it.

Overview

Microsoft Copilot Studio provides enterprise-grade support for Model Context Protocol (MCP), enabling organizations to connect AI agents with external data sources, tools, and business systems. By integrating Tallyfy’s MCP server with Copilot Studio, you can build intelligent agents that automate workflows, manage processes, and interact with your Tallyfy data using natural language.

This guide demonstrates how to configure Tallyfy’s MCP server with Microsoft Copilot Studio, leverage its unique enterprise features, understand limitations, and implement best practices for production deployments.

Microsoft Copilot Studio MCP support status

As of January 2025, Microsoft Copilot Studio’s MCP implementation includes:

• General availability: Full MCP support across all Copilot Studio plans
• Transport methods: Streamable HTTP (recommended) and Server-Sent Events (SSE, in preview)
• Enterprise features: Virtual Network integration, Data Loss Prevention (DLP), multiple authentication methods
• Platform integration: Native Power Platform connector infrastructure
• Prebuilt connectors: Dataverse, Dynamics 365 (Sales, Finance, Supply Chain, Service), Microsoft Fabric

Note: SSE transport support remains in preview and will be deprecated in August 2025. Microsoft recommends using Streamable HTTP for new implementations.

Prerequisites

Before setting up the integration, ensure you have:

• Microsoft Copilot Studio license (trial or paid)
• Tallyfy API key (available from your Tallyfy organization settings)
• Power Apps or Power Automate access (for creating custom connectors)
• Generative Orchestration enabled in your Copilot Studio agent
• Environment in a supported region (check Microsoft documentation for current availability)

Setting up Tallyfy MCP Server with Microsoft Copilot Studio

1. Create an MCP server for Tallyfy

   First, develop an MCP server that exposes Tallyfy’s capabilities. You can use Microsoft’s SDKs or deploy to Azure:

   // Example using Node.js on Azure Functions
   const { createMcpServer } = require('@microsoft/mcp-sdk');
   const axios = require('axios');
   
   module.exports = async function (context, req) {
     const server = createMcpServer({
       name: 'Tallyfy MCP Server',
       version: '1.0.0',
       tools: [
         {
           name: 'search_tasks',
           description: 'Search for tasks in Tallyfy',
           parameters: {
             query: { type: 'string', required: true },
             status: { type: 'string', enum: ['open', 'completed', 'overdue'] }
           },
           handler: async (params) => {
             const response = await axios.get('https://api.tallyfy.com/v1/tasks', {
               headers: { 'Authorization': `Bearer ${process.env.TALLYFY_API_KEY}` },
               params: { q: params.query, status: params.status }
             });
             return response.data;
           }
         }
       ]
     });
   
     context.res = await server.handleRequest(req);
   };

2. Create an OpenAPI specification

   Create a YAML file describing your MCP server for the Power Platform connector:

   swagger: '2.0'
   info:
     title: Tallyfy MCP Server
     description: MCP server for Tallyfy workflow management
     version: 1.0.0
   host: tallyfy-mcp.azurewebsites.net
   basePath: /api
   schemes:
     - https
   paths:
     /mcp:
       post:
         summary: Tallyfy Workflow Management Server
         x-ms-agentic-protocol: mcp-streamable-1.0
         operationId: InvokeMCP
         parameters:
           - name: Authorization
             in: header
             required: true
             type: string
             description: Bearer token for authentication
         responses:
           '200':
             description: Success
   securityDefinitions:
     apiKey:
       type: apiKey
       in: header
       name: Authorization

3. Create a custom connector in Power Apps

   1. Navigate to your Copilot Studio agent
   2. Go to Tools → Add a tool → New tool → Custom connector
   3. In Power Apps, select New custom connector → Import OpenAPI file
   4. Import your YAML specification and configure authentication

4. Configure authentication

   In the connector configuration:

   • Set authentication type to API Key
   • Configure the header name as Authorization
   • Set the prefix to Bearer
   • Test the connection with your Tallyfy API key

5. Add the MCP connector to your agent

   Back in Copilot Studio:

   1. Select Tools → Add a tool → Model Context Protocol
   2. Choose your Tallyfy MCP connector from the list
   3. Authorize the connection with your credentials
   4. Select Add to agent or Add and configure

6. Configure DLP policies (optional)

   For enterprise deployments:

   1. Navigate to Power Platform Admin Center
   2. Create DLP policies to control data flow
   3. Apply policies to your Copilot Studio environment
   4. Configure connector classifications (Business/Non-Business/Blocked)

7. Test the integration

   In your Copilot Studio agent, test with queries like:

   "Find all open tasks assigned to the sales team"
   "Show me overdue processes for customer onboarding"
   "Create a task for reviewing the Q4 budget"
