Integrating Claude Code with Lakebase Data via CData Connect AI

Claude Code is an AI-powered development environment that brings intelligent code generation, automation, and interactive reasoning directly into your workflow. By integrating it with CData Connect AI, you can enable Claude Code to securely access, query, and interact with live enterprise data, such as Lakebase, through a standardized MCP tool interface.

CData Connect AI is a managed MCP platform that exposes your enterprise data sources through the Model Context Protocol (MCP). This allows Claude Code to work with catalogs, schemas, tables, metadata, and SQL-enabled data access from hundreds of data sources, without requiring ETL pipelines or custom integration code.

This article explains how to register the CData Connect AI MCP endpoint in Claude Code, configure your Lakebase or other data source connection, and begin issuing real-time data queries directly from the coding environment. We explore how Claude Code uses the built-in MCP tools, such as getCatalogs, getSchemas, getTables, and queryData to help you write, debug, and automate development workflows powered by live Lakebase data securely and interactively.

Prerequisites

• An account in CData Connect AI
• A Claude Code account.
• Visual Studio Code installed on your system.

Step 1: Configure Lakebase connectivity for Claude Code

For Claude Code to access Lakebase, create a connection to Lakebase in CData Connect AI. This connection is then exposed to Claude Code using the remote MCP server.

1. Log in to Connect AI click Sources, and then click + Add Connection 👁 Adding a Connection
   
2. From the available data sources, choose Lakebase 👁 Selecting a data source
   
3. Enter the necessary authentication properties to connect to Lakebase To connect to Databricks Lakebase, start by setting the following properties:
   • DatabricksInstance: The Databricks instance or server hostname, provided in the format instance-abcdef12-3456-7890-abcd-abcdef123456.database.cloud.databricks.com.
   • Server: The host name or IP address of the server hosting the Lakebase database.
   • Port (optional): The port of the server hosting the Lakebase database, set to 5432 by default.
   • Database (optional): The database to connect to after authenticating to the Lakebase Server, set to the authenticating user's default database by default.

   OAuth Client Authentication

   To authenicate using OAuth client credentials, you need to configure an OAuth client in your service principal. In short, you need to do the following:

   1. Create and configure a new service principal
   2. Assign permissions to the service principal
   3. Create an OAuth secret for the service principal

   For more information, refer to the Setting Up OAuthClient Authentication section in the Help documentation.

   OAuth PKCE Authentication

   To authenticate using the OAuth code type with PKCE (Proof Key for Code Exchange), set the following properties:

   • AuthScheme: OAuthPKCE.
   • User: The authenticating user's user ID.

   For more information, refer to the Help documentation.

   👁 Configuring a connection (Salesforce is shown)
   
4. Click Save & Test
5. Once authenticated, open the Permissions tab in the Lakebase connection and configure user-based permissions as required 👁 Updating permissions
   

Generate a Personal Access Token (PAT)

Claude Code authenticates to Connect AI using an account email and a Personal Access Token (PAT). Creating separate PATs for each integration is recommended to maintain access control granularity.

1. In Connect AI, select the Gear icon in the top-right to open Settings
2. Under Access Tokens, select Create PAT
3. Provide a descriptive name for the token and select Create 👁 Creating a new PAT
   
4. Copy the token and store it securely. The PAT will only be visible during creation

With the Lakebase connection configured and a PAT generated, Claude Code is prepared to connect to Lakebase data through the CData MCP server.

Step 2: Install Claude Code

Claude Code is distributed as an npm package. You can install it globally.

To install Claude Code on your system, open PowerShell, Terminal, or CMD as an Administrator and run:

npm install -g @anthropic-ai/claude-code

Verify the installation using the following command:

npm list -g @anthropic-ai/claude-code

Expected output should be:

C:\Users\User\AppData\Roaming
pm
`-- @anthropic-ai/[email protected]

Step 3: Authenticate Claude Code with Claude.ai

Link your local Claude Code environment with your Claude.ai account to enable secure access. In the terminal, run:

claude login

Claude Code outputs a URL, like:

Please visit https://claude.ai/login?code=

Follow these steps:

1. Click the URL or paste it into your browser.
2. Log in to Claude.ai.
3. Claude.ai displays a verification code.
4. Return to your terminal and enter/paste the provided verification code when prompted.

Once verified, you'll need to authenticate with Claude Code using an authentication code. Once done, your terminal should display:

You're all set up for Claude Code.

Claude Code is now linked to your Claude.ai account.

Step 4: Create a Claude Code project

To set up a workspace where Claude Code can store MCP configuration files, start by creating a new directory:

mkdir ClaudeCode
cd ClaudeCode

Now, open it in Visual Studio Code:

code .

Step 5: Launch Claude Code and register the CData Connect AI MCP server

Before Claude Code can interact with Lakebase, you must register your CData Connect AI MCP endpoint. Claude Code uses this remote MCP server to securely access metadata, schemas, tables, and live query results.

Now register the CData Connect AI MCP server by running the following command in your Claude Code project directory:

claude mcp add connectmcp https://mcp.cloud.cdata.com/mcp \
 --transport http \
 --header "Authorization: Basic base64encoded(EMAIL:PAT)" \
 --header "Content-Type: application/json"

Once added, verify that Claude recognizes your MCP server:

claude mcp list

If successful, you should see:

connectmcp: https://mcp.cloud.cdata.com/mcp (HTTP) - ✓ OK

Start the Claude Code assistant and verify that it detects your MCP server. To run, use the given command:

claude

Once Claude Code loads, you should see:

Loaded MCP Server: connectmcp

This confirms that Claude Code is now connected to your CData Connect AI instance.

Step 6: Explore Lakebase metadata

You can now use Claude Code's natural-language interface to list catalogs, schemas, and tables in Lakebase. Ask Claude:

List all Lakebase catalogs using getCatalogs.

Claude automatically calls the appropriate MCP tool when you issue a request.

Try additional queries such as:

• "Show the available schemas."
• "List all tables in the Lakebase connection."
• "Retrieve the top 10 records from the Account table."

👁 Query Lakebase catalog to generate desired responses.

Claude Code uses the following MCP tools to interact with Lakebase in real time:

• getCatalogs
• getSchemas
• getTables
• queryData

These tools allow Claude Code to retrieve metadata and query live Lakebase data.

Step 7: Generate code and automation workflows

Use real Lakebase metadata to build working scripts directly inside your IDE.

Example prompt:

Write a Python script that queries Salesforce Contacts where LastName starts with 'A' using the MCP queryData tool.

👁 Prompt Lakebase connection to build working scripts.
👁 Prompt Lakebase connection to build working scripts (contd.)

Claude Code writes accurate code because it has:

• direct access to Lakebase schemas
• live query testing
• metadata introspection

All delivered through CData Connect AI.

Step 8: Build data-driven development workflows

Use Claude Code to generate, refine, and automate code that works with your Lakebase data using CData Connect AI.

With the CData Connect AI integration in place, Claude Code can help you build development workflows that rely on your Lakebase data. Although Claude Code does not include built-in real-time data connectivity, your configured MCP connection through CData Connect AI provides it with access to the metadata and query results for your request.

You can use Claude Code to automate tasks such as:

• generating scripts for data exploration
• creating integration test scaffolding
• validating queries against your Lakebase schema
• producing code for data extraction or transformation workflows

In this setup, Claude Code acts as an intelligent coding assistant that uses live Lakebase data from CData Connect AI to help you write and refine data-driven logic.

Optional: Manage MCP integrations

Add, remove, or inspect MCP servers in your project.

List MCP servers using the following command:

claude mcp list

To remove one, use:

claude mcp remove connectmcp

Modify the config by editing:

.claude/mcp.json
