The CData MCP Server for Sybase defines each connection to Sybase 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/Sybase Data Provider/".
• On macOS, configuration files are stored in "~/Library/Application Support/CData/Sybase 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 Sybase

To connect to the Sybase, specify the following connection properties:

• Server: Set this to the name or network address of the Sybase database instance.
• Database: Set this to the name of the Sybase database running on the specified Server.

Optionally, you can also secure your connections with TLS/SSL by setting UseSSL to true.

Authenticating to Sybase

Sybase supports several methods for authentication including basic, Kerberos, and, LDAP.

Basic

Set the AuthScheme to Basic and set the following connection properties to use Sybase authentication.

• User: Set this to the username of the authenticating Sybase user.
• Password: Set this to the username of the authenticating Sybase user.

LDAP

To connect with LDAP authentication, you will need to configure Sybase server-side to use the LDAP authentication mechanism.

After configuring Sybase for LDAP, you can connect using the same credentials as basic authentication.

Kerberos

To leverage Kerberos authentication, begin by enabling it via the following connection property:

• AuthScheme: Set to Kerberos will be used for authentication to Sybase.

See Using Kerberos information regarding the connection properties that need to be set for Kerberos authentication.

You can find an example connection string below:

Server=MyServer;Port=MyPort;User=SampleUser;Password=SamplePassword;Database=MyDB;Kerberos=true;KerberosKDC=MyKDC;KerberosRealm=MYREALM.COM;KerberosSPN=server-name
