Query Live JSON Data in Perplexity Desktop via CData Connect AI

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

Integrating Perplexity Desktop with CData Connect AI via its built-in MCP connector allows the AI to query, explore, and reason over live JSON services without copying data out of its source system. The result is a research experience where you can ask questions about your governed enterprise data directly from Perplexity Desktop.

This article outlines how to configure JSON connectivity in Connect AI, generate the required access token, register Connect AI's MCP Server in Perplexity Desktop, and then use the chat interface to explore live JSON services.

Step 1: Configure JSON connectivity for Perplexity Desktop

Connectivity to JSON from Perplexity Desktop is made possible through CData Connect AI's Remote MCP Server. To interact with JSON services from Perplexity Desktop, start by creating and configuring a JSON connection in CData Connect AI.

1. Log into Connect AI, click Sources, and then click Add Connection

2. Select JSON from the Add Connection panel

3. Enter the necessary authentication properties to connect to JSON.

   See the Getting Started chapter in the data provider documentation to authenticate to your data source: The data provider models JSON APIs as bidirectional database tables and JSON files as read-only views (local files, files stored on popular cloud services, and FTP servers). The major authentication schemes are supported, including HTTP Basic, Digest, NTLM, OAuth, and FTP. See the Getting Started chapter in the data provider documentation for authentication guides.

   After setting the URI and providing any authentication values, set DataModel to more closely match the data representation to the structure of your data.

   The DataModel property is the controlling property over how your data is represented into tables and toggles the following basic configurations.

   • Document (default): Model a top-level, document view of your JSON data. The data provider returns nested elements as aggregates of data.
   • FlattenedDocuments: Implicitly join nested documents and their parents into a single table.
   • Relational: Return individual, related tables from hierarchical data. The tables contain a primary key and a foreign key that links to the parent document.

   See the Modeling JSON Data chapter for more information on configuring the relational representation. You will also find the sample data used in the following examples. The data includes entries for people, the cars they own, and various maintenance services performed on those cars.

   
4. Click Save & Test
5. Navigate to the Permissions tab and update user-based permissions

Add a Personal Access Token

A Personal Access Token (PAT) is used to authenticate the connection to Connect AI from Perplexity Desktop. It is best practice to create a separate PAT for each integration to maintain granular access control.

1. Click the gear icon () at the top right of the Connect AI app to open Settings
2. On the Settings page, go to the Access Tokens section and click Create PAT
3. Give the PAT a descriptive name and click Create

4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use

Create an OAuth App in CData Connect AI

Perplexity Desktop uses OAuth 2.0 to authenticate users against the CData Connect AI MCP Server. This requires creating an OAuth App in your CData Connect AI account.

1. Click the Gear icon () in the top-right corner of Connect AI to open Settings
2. Navigate to OAuth Apps and click + Create App. The Create OAuth App dialog appears
3. Fill in the following fields:
   • Name — Enter a descriptive name (e.g.,

     PerplexityOAuth

     )
   • Authentication Flow — Select User-based (Authorization Code)
   • Callback URL — Enter the callback URL provided by Perplexity Desktop when adding the connector
   
4. Click Confirm. CData Connect AI generates a Client ID and Client Secret
5. Copy both values and store them securely. You will need them in Step 2

With the JSON connection configured and an OAuth App created, Perplexity Desktop can now connect to JSON services through Connect AI.

Step 2: Configure Connect AI in Perplexity Desktop

Next, register the CData Connect AI MCP Server as a custom remote connector in Perplexity Desktop. This feature requires a Perplexity Pro, Max, or Enterprise account and the macOS desktop app. Once configured, Perplexity's AI can call the tools exposed by CData Connect AI to access live JSON services.

1. Download the Perplexity Desktop application for macOS and sign in with your Pro, Max, or Enterprise 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 Custom Remote Connector
4. In the URL field, enter the CData Connect AI MCP endpoint:

   https://mcp.cloud.cdata.com/mcp

   
5. For the authentication method, select OAuth. Enter the Client ID and Client Secret from the OAuth App created in Step 1, and click Connect
6. You will be redirected to CData Connect AI to authorize the connection. Sign in and click Allow to grant Perplexity access
7. After successful authorization, you will be redirected back to Perplexity Desktop. The connector should now appear in the list with an active status

Step 3: Query your live JSON services from Perplexity Desktop

1. Open a new chat in Perplexity Desktop. Click the Sources toggle and enable your CData connector
2. Start asking questions about your JSON services. For example:

   "List all the tables available in my JSON services connection."

   
3. Try additional queries such as:
   • "Show the available schemas in JSON."
   • "Retrieve the top 10 records from the Account table."
   • "Summarize the high-priority open opportunities in JSON."

Perplexity Desktop is now fully integrated with the CData Connect AI MCP Server and can reason over live JSON services directly from the chat interface.
