Integrate Devin with Live Neo4J Data Using CData Connect AI

Devin is an AI software engineer from Cognition that plans, writes, and tests code in autonomous sessions. It supports the model context protocol (MCP) through its built-in MCP marketplace, allowing you to install remote MCP servers and give Devin access to external tools and live data sources.

By integrating Devin with CData Connect AI through the built-in MCP Server, Devin gains governed, real-time access to live Neo4J data. You can list catalogs, explore schemas, and query records from Neo4J data using natural language prompts, with all data access running securely against authorized sources.

This article explains how to configure Neo4J connectivity in Connect AI, install the CData Connect AI MCP Server from the Devin MCP marketplace, and verify the integration by querying live Neo4J data from a Devin session.

Step 1: Configure Neo4J connectivity for Devin

Connectivity to Neo4J from Devin is made possible through Connect AI's Remote MCP Server. To interact with Neo4J data from Devin, start by creating and configuring a Neo4J connection in Connect AI.

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

2. Select Neo4J from the Add Connection panel

3. Enter the necessary authentication properties to connect to Neo4J.

   To connect to Neo4j, set the following connection properties:

   • Server: The server hosting the Neo4j instance.
   • Port: The port on which the Neo4j service is running. The provider connects to port 7474 by default.
   • User: The username of the user using the Neo4j instance.
   • Password: The password of the user using the Neo4j instance.
   
4. Click Save & Test
5. Navigate to the Permissions tab and update user-based permissions

With the Neo4J connection configured, Devin can now connect to Neo4J data through Connect AI.

Step 2: Install the Connect AI MCP Server in Devin

Next, install the CData Connect AI MCP Server from the Devin MCP servers list so your sessions can discover and call live data tools through Connect AI.

Note: Installing MCP servers in Devin requires the Manage MCP Servers permission. If you don't have this permission, use the Suggest option or contact your organization admin.

1. Log into Devin and navigate to Settings and Connections, then select the MCP servers tab
2. Search for CData Connect AI in the marketplace and select the verified listing

3. Click Install and enable. When prompted, complete the OAuth flow to authenticate with your Connect AI account
4. Once installed, confirm the Enable in sessions toggle is on and click Test tools. Devin validates the connection and lists the available Connect AI tools, such as getCatalogs, getSchemas, getTables, and queryData

With the MCP server installed and enabled, the Connect AI tools are available to every Devin session in your workspace.

Step 3: Query live Neo4J data from Devin

With the integration complete, start a Devin session and interact with live Neo4J data through natural language prompts.

1. From the Devin home page, start a new session
2. In the session prompt, ask Devin to work with your Connect AI data, for example:
   • Can you list the connections in CData Connect AI
   • Show the available schemas and tables for Neo4J
   • Query the top 5 records from a table in Neo4J
3. Devin calls the Connect AI MCP Server and returns live results from Neo4J data directly in the session. You can follow the tool calls, inputs, and outputs in the Progress panel

At this point, Devin communicates with the Connect AI MCP Server and retrieves live Neo4J data through remote MCP tools directly from your sessions, whether you're exploring data, building features against it, or automating engineering tasks.
