Establishing a Connection
The CData MCP Server for SingleStore defines each connection to SingleStore 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/SingleStore Data Provider/".
- On macOS, configuration files are stored in "~/Library/Application Support/CData/SingleStore 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 SingleStore
The following connection properties are required in order to connect to data.
- Server: The host name or IP of the server hosting the SingleStore database.
- Port: The port of the server hosting the SingleStore database.
You can also optionally set the following:
- Database: The default database to connect to when connecting to the SingleStore Server. If this is not set, tables from all databases will be returned.
Standard Authentication
To authenticate using standard authentication, set the following:
- User: The user which will be used to authenticate with the SingleStore server.
- Password: The password which will be used to authenticate with the SingleStore server.
Connect Using Integrated Security
As an alternative to providing the standard username and password, you can authenticate trusted users to the server via Windows Authentication.
SSL Authentication
You can leverage SSL authentication to connect to SingleStore data via a secure session. Configure the following connection properties to connect to data:
- SSLClientCert: Set this to the name of the certificate store for the client certificate. Used in the case of 2-way SSL, where truststore and keystore are kept on both the client and server machines.
- SSLClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
- SSLClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
- SSLClientCertType:; The certificate type of the client store.
- SSLServerCert: The certificate to be accepted from the server.
SSH Authentication
Using SSH, you can securely login to a remote machine. To access SingleStore data via SSH, configure the following connection properties:
- SSHClientCert: Set this to the name of the certificate store for the client certificate.
- SSHClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
- SSHClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
- SSHClientCertType: The certificate type of the client store.
- SSHPassword: The password that you use to authenticate with the SSH server.
- SSHPort: The port used for SSH operations.
- SSHServer: The SSH authentication server you are trying to authenticate against.
- RSBSinglestore_p_SSHServerFingerprint: The SSH Server fingerprint used for verification of the host you are connecting to.
- SSHUser: Set this to the username that you use to authenticate with the SSH server.
