Add a script to start the MCP server on every LLM client

[Rodriguespn]

Overview

We want to streamline the setup of the MCP server for users across various LLM clients. This issue tracks adding a script that:

• Configures the MCP server to run with a specific client
• Updates the corresponding client’s config file automatically

Goals

• Support the following LLM clients:
• Claude Desktop (default)
• Cursor
• Windsurf
• GitHub Copilot

Provide a single command for users to run:

pipx run singlestore-mcp-server init <SINGLESTORE_API_KEY> --client=claude

If no --client flag is passed, default to Claude.

Functionality

When the command is run:

• A configuration entry should be written/updated in the corresponding client’s config file to point to the MCP server.
• Include helpful CLI output for debugging and confirming the setup.
• If the client is unsupported or misconfigured, show a clear error message.

Testing

• Validate setup works end-to-end for each supported client.
• Confirm that config files are updated correctly.
• Ensure no-op or graceful errors when run on unsupported systems or clients.

Notes

• Each client may require slightly different paths/config formats — add support incrementally if needed.
• Consider prompting the user to install the MCP server if it’s not already installed.
