How to Query Live Outlook Data in Perplexity MacOS Desktop

Perplexity is an AI-powered research and answer engine that allows users to combine web search, structured data, and connected tools through a unified conversational interface. With Perplexity Desktop for macOS, users can bring local tools and data sources directly into their workflow using MCP, enabling fast, context-aware insights powered by live data.

Model Context Protocol (MCP) is an emerging, open-source standard for connecting LLMs with external services and enterprise data sources. Using MCP Servers, AI clients such as Perplexity Desktop can securely interact with applications and data, performing actions, retrieving live information, and enabling natural language access to data.

CData MCP Server provides schema-aware context to AI tools — whether you're using it for AI-assisted code generation in IDEs like Cursor, or for querying live data through chat interfaces like Perplexity Desktop.

In this article, we guide you through installing CData API Driver for MCP Server, configuring the connection to Outlook, and interacting with your live Outlook data from Perplexity Desktop.

Step 1: Download and install CData API Driver for MCP Server

1. To begin, download CData API Driver for MCP Server
2. Find and double-click the installer to begin the installation
3. Drag the MCP Server app into the Applications folder

When the installation is complete, you are ready to configure MCP Server by connecting to Outlook.

NOTE: Since you downloaded the application from the internet and not the Apple App Store, you may see a warning that the application was not opened because Apple could not verify its security. You may continue with the installation.

Installing a trusted, unverified App

CData's solutions are trusted across the globe by some of the largest software vendors in the world. That said, if you have any concerns about continuing, please consult with your IT and/or security team.

1. In the warning message that pops up, click "Done"
2. Open "System Settings" on your machine and navigate to the "Privacy & Security" page

3. Scroll down to the "Security" section and click "Open Anyway"
4. Authorize the installation (passkey or password)

Step 2: Configure the Connection to Outlook

1. After installation, you can open CData API Driver for MCP Server from the Applications folder on your mac
2. Click the dropdown menu in MCP Configuration > Configuration Name and select "new configuration"
3. Name the configuration (e.g. "cdata_api") and click "OK"

4. Enter the appropriate connection properties in the configuration wizard.

   Using OAuth Authentication

   Microsoft Graph API uses OAuth 2.0 for authentication. You must register an application in the Microsoft Azure Portal to obtain OAuth credentials (Client ID and Client Secret).

   Obtaining OAuth Credentials

   1. Log in to the Azure Portal.
   2. Navigate to Azure Active Directory > App registrations.
   3. Click New registration to create a new application.
   4. Enter an application name and select the appropriate account types.
   5. Set the Redirect URI to your application's callback URL (e.g., http://localhost:33333 for desktop apps).
   6. Click Register to create the application.
   7. On the application overview page, copy the Application (client) ID - this is your OAuthClientId.
   8. Navigate to Certificates & secrets and create a new client secret.
   9. Copy the client secret value - this is your OAuthClientSecret.
   10. Navigate to API permissions and add the required Microsoft Graph API permissions:
       • Mail.Read - For accessing email messages
       • Contacts.Read - For accessing contacts
       • Calendars.Read - For accessing calendar events
       • Tasks.Read - For accessing To Do tasks
       • offline_access - For obtaining refresh tokens
   11. Click Grant admin consent to grant these permissions.

   Connecting with OAuth

   After setting the following connection properties, you are ready to connect:

   • AuthScheme: Set this to OAuth.
   • InitiateOAuth: Set this to GETANDREFRESH. The CData API Profile for Outlook will automatically walk through the OAuth process in order to obtain the access token.
   • OAuthClientId: Set this to the Application (client) ID from Azure Portal.
   • OAuthClientSecret: Set this to the client secret value from Azure Portal.
   • TenantId: Set this to your Azure AD tenant identifier (GUID or domain name like 'contoso.onmicrosoft.com').
   • CallbackURL: Set this to the Redirect URI you specified in your app registration (e.g., http://localhost:33333 for desktop apps).

   Example connection string

   Profile=C:\profiles\Outlook.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;TenantId=your_tenant_id;CallbackUrl=http://localhost:33333;
   

   
5. Click "Connect" to authenticate with Outlook through OAuth.
6. Click "Save Configuration" to save the configuration

With MCP Server configured, you are ready to connect it to Perplexity Desktop.

Step 3: Connect MCP Server to Perplexity Desktop

1. Download the Perplexity Desktop application for macOS and sign in with your Pro or Premium account
2. Open Settings > Connectors. If the Perplexity Helper App is not installed, you will be prompted to download it. Install the Helper App, then restart Perplexity Desktop
3. After restarting, return to Settings > Connectors and click Add Connector
4. Select the Simple tab and assign a name for the connector (e.g., "CData Outlook"). In the Command box, enter the absolute path to the MCP Server executable.

   For example:

   	/Applications/CData API Driver for MCP Server.app/Contents/Payload/jre/Contents/Home/bin/java \
   	-jar /Applications/CData API Driver for MCP Server.app/Contents/Payload/lib/cdata.mcp.api.jar \
   	cdata_api
   

   
5. Click Save. MCP Server should now appear in the connector list with a "Running" status

Step 4: Query Your Live Outlook data in Perplexity Desktop

1. Open a new chat in Perplexity Desktop. Click the Sources toggle and enable MCP Server
2. Start asking questions about your Outlook data. For example:

   "List all the tables available in my Outlook data connection."
