How to Connect Flowise AI Agents to Live Elasticsearch Data via CData Connect AI

Flowise AI is an open-source, no-code tool for building AI workflows and custom agents visually. Its drag-and-drop interface allows you to integrate large language models (LLMs) with APIs, databases, and external systems effortlessly.

CData Connect AI enables real-time connectivity to hundreds of enterprise data sources. Through its Model Context Protocol (MCP) server, CData Connect AI bridges Flowise agents with live Elasticsearch securely and efficiently, no data replication required. By combining Flowise AI's intuitive agent builder with CData's MCP integration, users can create agents capable of fetching, analyzing, and acting upon live Elasticsearch data directly within Flowise AI workflows.

This guide shows you how to connect Flowise AI to CData Connect AI MCP, set up credentials, and enable your agents to query live Elasticsearch data in real time.

Getting Started

Step 1: Configure Elasticsearch Connectivity for Flowise

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

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

2. Select Elasticsearch from the Add Connection panel

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

   Set the Server and Port connection properties to connect. To authenticate, set the User and Password properties, PKI (public key infrastructure) properties, or both. To use PKI, set the SSLClientCert, SSLClientCertType, SSLClientCertSubject, and SSLClientCertPassword properties.

   The data provider uses X-Pack Security for TLS/SSL and authentication. To connect over TLS/SSL, prefix the Server value with 'https://'. Note: TLS/SSL and client authentication must be enabled on X-Pack to use PKI.

   Once the data provider is connected, X-Pack will then perform user authentication and grant role permissions based on the realms you have configured.

Once the connection is established, Elasticsearch data is now accessible in CData Connect AI and ready to be used with MCP enabled tools.

Add a Personal Access Token

A Personal Access Token (PAT) is used to authenticate the connection to Connect AI from Flowise AI. 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. Copy the token when displayed and store it securely. It will not be shown again

With the Elasticsearch connection configured and a PAT generated, Flowise AI can now connect to Elasticsearch data through Connect AI.

Step 2: Configure Connect AI credentials in Flowise AI

Log in to Flowise AI workspace to set up the integration.

Add OpenAI credentials

1. Navigate to Credentials and choose Add Credential
👁 Click Add credential

2. Select OpenAI API from the dropdown
3. Provide a name (e.g., OpenAI_Key) and paste the API key

Add the PAT variable

1. Navigate to Variables and Add Variable
👁 Navigate to Variables

2. Set Variable Name (e.g., PAT), choose Static as type, and set the Value to Base64-encoded username:PAT
3. Click Add to save the variable

Step 3: Build the agent in Flowise AI

1. Go to Agent Flows, select Add New
👁 Agent Flow page

2. Click the "+" icon to add a new node and choose Agent and drag the agent to the workflow

Configure agent settings

Double-click on the Agent node and fill in the details:

• Model: select ChatOpenAI or preferred model (e.g., gpt-4o-mini)
• Connect Credential: Select OpenAI API key credential which was created earlier
• Streaming: Enabled

👁 Fill in the details for Agent Node

Add the custom MCP tool

1. Under Tools, click Add Tool and choose Custom MCP
2. Fill in the JSON parameters as shown below:

 
{
 "url": "https://mcp.cloud.cdata.com/mcp",
 "headers": {
 "Authorization": "Basic {{$vars.PAT}}"
 }
}

👁 Configuring custom MCP tool in Flowise

Click the refresh icon to load available MCP actions. Once actions are listed, now Flowise agent is successfully connected to CData Connect AI MCP.

Step 4: Test and query live Elasticsearch data in Flowise

1. Open the Chat tab in Flowise
2. Type a query such as "Show top 10 records from Elasticsearch data table"
3. Observe that responses are fetched in real time via the CData Connect AI MCP connection
👁 Testing live queries in Flowise

With the workflow run completed, Flowise demonstrates successful retrieval of Salesforce data through the CData Connect AI MCP server, with the MCP Client node providing the ability to ask questions, retrieve records, and perform actions on the data.
