⚠️ Important Warnings: Read Before Use
Data Privacy
When you use this MCP server, any data retrieved by the tools (like your account usage, phone numbers, or bill details) is sent to the Large Language Model (LLM) that powers your MCP client. This means a third-party company (e.g., OpenAI, Google, Anthropic) will process this potentially sensitive information. Please be aware of the privacy implications and review your LLM provider's policies before using this server.
Financial Risk
This server provides tools that can change your mobile account settings in real-time. Actions like toggle_roaming or set_call_forwarding_rule can lead to significant, real-world charges on your phone bill, especially if misconfigured. You are solely responsible for any and all costs incurred as a result of using these tools. Use them with extreme caution.
