How to Query Live Oracle 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.

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

Step 1: Download and install the CData MCP Server for Oracle

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

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

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 Oracle

1. After installation, you can open the CData MCP Server for Oracle 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_oracleoci") and click "OK"

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

   To connect to Oracle, you'll first need to update your PATH variable and ensure it contains a folder location that includes the native DLLs. The native DLLs can be found in the lib folder inside the installation directory. Once you've done this, set the following to connect:

   • Port: The port used to connect to the server hosting the Oracle database.
   • User: The user Id provided for authentication with the Oracle database.
   • Password: The password provided for authentication with the Oracle database.
   • Service Name: The service name of the Oracle database.
   
5. Click "Connect" to authenticate with Oracle.
6. Click "Save Configuration" to save the MCP server

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

Step 3: Connect the 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 Oracle MCP"). In the Command box, enter the absolute path to your MCP Server executable.

   For example:

   	/Applications/CData MCP Server for Oracle.app/Contents/Payload/jre/Contents/Home/bin/java \
   	-jar /Applications/CData MCP Server for Oracle.app/Contents/Payload/lib/cdata.mcp.oracleoci.jar \
   	cdata_oracleoci
   

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

Step 4: Query Your Live Oracle data in Perplexity Desktop

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

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