The CData MCP Server for ADP defines each connection to ADP as a named configuration that Claude can use when sending natural language queries.

You create and manage these configurations using the MCP Configuration Tool. The tool automatically handles formatting, storage, and registration with Claude Desktop.

Understanding Connection Configurations

Each connection configuration is stored in a .mcp file. This file includes the details needed to initialize the connector when Claude starts a session.

• On Windows, configuration files are stored in "~/AppData/Roaming/CData/ADP Data Provider/".
• On macOS, configuration files are stored in "~/Library/Application Support/CData/ADP Data Provider/".

The .mcp file is a text file that contains a list of connection properties and a timestamp. For example:

#Tue May 20 15:48:40 EDT 2025
AuthScheme=Basic
User=myUser
Password=myPassword
Security Token=myToken

The configuration tool handles these settings automatically. Each saved configuration enables Claude to launch a dedicated MCP Server instance with the correct connector and options. Manual file editing is not required.

Connecting to ADP

Before configuring your connection, ensure you have obtained and formatted your SSL client certificate as described in Before You Connect.

To connect to ADP, set the following properties:

• OAuthClientId: The client Id of the custom OAuth application you obtained from ADP.
• OAuthClientSecret: The custom OAuth application's client secret.
• SSLClientCert: The full file path to your SSL client certificate. If using a .pem file, ensure it contains both the Private Key and Public Certificate. If using a .pfx file, ensure it was created with the correct export password. See Before You Connect for more information.
• SSLClientCertPassword: The password for the SSL client certificate, if applicable.
• UseUAT: The server makes requests to the production environment by default. If using a developer account, set UseUAT = true.
• RowScanDepth: The maximum number of rows to scan for the custom fields columns available in the table (default=100). Setting a high value may decrease performance.
