Leverage the CData Connect AI Remote MCP Server to enable LibreChat to securely access and query live Elasticsearch data from within the chat interface.

LibreChat is an open-source, self-hosted AI chat platform that brings together multiple LLM providers, agents, and assistants behind a single interface. It also supports the Model Context Protocol (MCP), so you can connect external tools and data sources directly to the chat and pull in live data from the systems you already work with.

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

This article explains how to configure Elasticsearch connectivity in Connect AI, generate the required personal access token, install LibreChat, register the Connect AI MCP Server, configure an LLM provider, and verify the integration by querying live Elasticsearch data from the LibreChat interface.

About Elasticsearch Data Integration

Accessing and integrating live data from Elasticsearch has never been easier with CData. Customers rely on CData connectivity to:

  • Access both the SQL endpoints and REST endpoints, optimizing connectivity and offering more options when it comes to reading and writing Elasticsearch data.
  • Connect to virtually every Elasticsearch instance starting with v2.2 and Open Source Elasticsearch subscriptions.
  • Always receive a relevance score for the query results without explicitly requiring the SCORE() function, simplifying access from 3rd party tools and easily seeing how the query results rank in text relevance.
  • Search through multiple indices, relying on Elasticsearch to manage and process the query and results instead of the client machine.

Users frequently integrate Elasticsearch data with analytics tools such as Crystal Reports, Power BI, and Excel, and leverage our tools to enable a single, federated access layer to all of their data sources, including Elasticsearch.

Getting Started


Step 1: Configure Elasticsearch connectivity for LibreChat

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

  1. Log into Connect AI, click Sources, and then click Add Connection
    2. 👁 Adding a connection in Connect AI
  2. Select Elasticsearch from the Add Connection panel
    3. 👁 Selecting data source
  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.

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

Add a Personal Access Token

A Personal Access Token (PAT) is used to authenticate the connection to Connect AI from LibreChat. 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. 👁 Creating a new PAT
  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, LibreChat can now connect to Elasticsearch data through Connect AI.

Step 2: Install LibreChat and configure Connect AI MCP

Next, install LibreChat locally and configure the Connect AI Remote MCP Server so that the chat interface can discover and call live data tools through Connect AI.

  1. Install LibreChat by following the official installation guide. If you are using the npm setup, make sure MongoDB and MeiliSearch are installed and running locally
  2. Once the installation is complete, start LibreChat and open http://localhost:3080/ in your browser to access the chat interface 👁 LibreChat chat interface
  3. In the left navigation bar, click the MCP Settings icon, then click Add MCP 👁 Adding a new MCP server in LibreChat
  4. In the Add MCP panel, configure the server with the following values:
    • Name: CData MCP, or any name of your choice
    • Description: Optional description for the server
    • MCP Server URL: https://mcp.cloud.cdata.com/mcp
    • Transport: Streamable HTTPS
    • Authentication: API Key
    • Header Format: Basic
    • API Key: base64-encoded value of email:PAT

    Note: LibreChat will use Basic authentication with Connect AI. Combine your Connect AI user email and the PAT you created earlier in the format email:PAT, then base64 encode the combined string and paste it in the API Key field. For example, [email protected]:ABC123...XYZ789 base64-encoded becomes something like: dXNlckBkb21haW4uY29tOkFCQzEyMy4uLlhZWjc4OQ==

  5. Check I trust this application and click Add to save the server
  6. The CData MCP server now appears in the left navigation bar. Click the connect icon next to it to establish the connection to Connect AI 👁 CData MCP server connected in LibreChat

Enable the MCP server and configure an LLM provider

LibreChat requires at least one LLM provider to power the chat. Enable the MCP server in the chat input and add an API key for your preferred provider so the model can interpret prompts and call MCP tools through Connect AI.

  1. In the chat interface, click the MCP selector at the bottom of the input box and confirm that CData MCP is checked so the tools are exposed to the chat 👁 Enabling the CData MCP server in the chat input
  2. At the top of the chat, click the model selector and choose your preferred LLM provider (e.g., OpenAI, Anthropic, Google) and model 👁 Selecting an LLM provider and model
  3. Click Set API Key next to the chosen provider, paste your provider API key, and click Submit 👁 Setting the LLM provider API key

With the MCP server and an LLM provider configured, LibreChat is ready to query live Elasticsearch data through Connect AI.

Step 3: Query live Elasticsearch data from LibreChat

With the integration complete, use the LibreChat chat input to interact with live Elasticsearch data through natural language prompts handled by the configured LLM.

  1. With the CData MCP server enabled and a model selected, type a prompt in the chat input, for example:
    • List all catalogs in my cdata mcp
    • Show the available schemas and tables for Elasticsearch
    • Query the top 5 records from a table in Elasticsearch data
  2. LibreChat calls the Connect AI MCP Server and returns live results from Elasticsearch data 👁 Querying live data from LibreChat

At this point, your LibreChat instance communicates with the Connect AI MCP Server and retrieves live Elasticsearch data through remote MCP tools directly from the chat interface.
