- Read-only access to email data via the CData JDBC Driver
- Natural language querying – no SQL required
- Pre-built tools: list tables, list columns, run SQL SELECT
- Customizable table prefix, server name, and table selection
- Supports any data source the CData JDBC Driver can connect to
Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
CData Email ServerCommand (node, npx, python, etc.)Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
Clone the repository, build the JAR with Maven, download and license the CData JDBC Driver for Email, configure a .prp file with your connection details, then add the server to your MCP client’s configuration (e.g., claude_desktop_config.json). The server uses stdio transport and runs only on the same machine as the client.
Claude Desktop / Cursor
Paste into your MCP client config file to install this server.

CData's Model Context Protocol (MCP) Server for Email
:heavy_exclamation_mark: This project builds a read-only MCP server. For full read, write, update, delete, and action capabilities and a simplified setup, check out ourCData MCP Server for Email.
We created this read-only MCP Server to allow LLMs (like Claude Desktop) to query live data Email supported by theCData JDBC Driver for Email.
CData JDBC Driver connects to Email by exposing them as relational SQL models.
This server wraps that driver and makes Email data available through a simple MCP interface, so LLMs can retrieve live information by asking natural language questions — no SQL required.
- Clone the repository:
git clone https://github.com/cdatasoftware/email-mcp-server-by-cdata.git cd email-mcp-server-by-cdata
- Navigate to thelibfolder in the installation directory, typically:
- (Windows)C:\Program Files\CData\CData JDBC Driver for Email\
- (Mac/Linux)/Applications/CData JDBC Driver for Email/
-
Run the commandjava -jar cdata.jdbc.email.jarto open the Connection String utility.
Configure the connection string and click "Test Connection"
Note:If the data sources uses OAuth, you will need to authenticate in your browser.
Once successful, copy the connection string for use later.
- Prefix- a prefix to be used for the tools exposed
- ServerName- a name for your server
- ServerVersion- a version for your server
- DriverPath- the full path to the JAR file for your JDBC driver
- DriverClass- the name of the JDBC Driver Class (e.g. cdata.jdbc.email.EmailDriver)
- JdbcUrl- the JDBC connection string to use with the CData JDBC Driver to connect to your data (copied from above)
- Tables- leave blank to access all data, otherwise you can explicitly declare the tables you wish to create access for
Prefix=email ServerName=CDataEmail ServerVersion=1.0 DriverPath=PATH\TO\cdata.jdbc.email.jar DriverClass=cdata.jdbc.email.EmailDriver JdbcUrl=jdbc:email:InitiateOAuth=GETANDREFRESH; Tables=

Create the config file for Claude Desktop ( claude_desktop_config.json) to add the new MCP server, using the format below. If the file already exists, add the entry to themcpServersin the config file.
{ "mcpServers": { "{classname_dash}": { "command": "PATH\\TO\\java.exe", "args": [ "-jar", "PATH\\TO\\CDataMCP-jar-with-dependencies.jar", "PATH\\TO\\email.prp" ] }, ... } }
{ "mcpServers": { "{classname_dash}": { "command": "/PATH/TO/java", "args": [ "-jar", "/PATH/TO/CDataMCP-jar-with-dependencies.jar", "/PATH/TO/email.prp" ] }, ... } }
If needed, copy the config file to the appropriate directory (Claude Desktop as the example).Windows
cp C:\PATH\TO\claude_desktop_config.json %APPDATA%\Claude\claude_desktop_config.json
cp /PATH/TO/claude_desktop_config.json /Users/{user}/Library/Application\ Support/Claude/claude_desktop_config.json'
Run or refresh your client (Claude Desktop).
Note:You may need to fully exit or quit your Claude Desktop client and re-open it for the MCP Servers to appear.
- Run the follow the command to run the MCP Server on its own
java -jar /PATH/TO/CDataMCP-jar-with-dependencies.jar /PATH/TO/Salesforce.prp
Note:The server usesstdioso can only be used with clients that run on the same machine as the server.
Once the MCP Server is configured, the AI client will be able to use the built-in tools to read, write, update, and delete the underlying data. In general, you do not need to call the tools explicitly. Simply ask the client to answer questions about the underlying data system. For example:
- "What is the correlation between my closed won opportunities and the account industry?"
- "How many open tickets do I have in the SUPPORT project?"
- "Can you tell me what calendar events I have today?"
The list of tools available and their descriptions follow:
In the definitions below,{servername}refers to the name of the MCP Server in the config file (e.g.{classname_dash}above).
- {servername}_get_tables- Retrieves a list of tables available in the data source. Use the{servername}_get_columnstool to list available columns on a table. The output of the tool will be returned in CSV format, with the first line containing column headers.
- {servername}_get_columns- Retrieves a list of columns for a table. Use the{servername}_get_tablestool to get a list of available tables. The output of the tool will be returned in CSV format, with the first line containing column headers.
- {servername}_run_query- Execute a SQL SELECT query
If you are scripting out the requests sent to the MCP Server instead of using an AI Client (e.g. Claude), then you can refer to the JSON payload examples below – following the JSON-RPC 2.0 specification - when calling the available tools.
{ "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "source_get_tables", "arguments": {} } }
{ "jsonrpc": "2.0", "id": 2, "method": "tools/call", "params": { "name": "source_get_columns", "arguments": { "table": "Account" } } }
{ "jsonrpc": "2.0", "id": 3, "method": "tools/call", "params": { "name": "source_run_query", "arguments": { "sql": "SELECT * FROM [Account] WHERE [IsDeleted] = true" } } }
- If you cannot see your CData MCP Server in Claude Desktop, be sure that you have fully quit Claude Desktop (Windows: use the Task Manager, Mac: use the Activity Monitor)
- If Claude Desktop is unable to retrieve data, be sure that you have configured your connection properly. Use the Connection String builder to create the connection string (see above) and copy the connection string into the property (.prp) file.
- If you are having trouble connecting to your data source, contact theCData Support Team.
