If you are using a shared/common Claude account, avoid connecting your Titan mailbox through MCP.

Your Titan login session may remain available across shared Claude instances, which can allow other shared users to access your mailbox.

  • Use only your personal Claude or ChatGPT account
  • Do not connect Titan Mail on shared/public AI accounts
  • Always log out from unused sessions
alert-warning

Tool Permission Settings

After connecting Titan MCP, Claude allows you to control how MCP tools are used.

  • Always allow – Claude can use Titan MCP tools automatically without asking for approval.
  • Needs approval – Claude will ask for your permission before using a Titan MCP tool.
  • Blocked – Prevents Claude from using the selected Titan MCP tool.
  • Custom – Configure permissions individually for specific tools.

For the best experience, we recommend keeping the default setting of Always allow unless you prefer additional approval prompts for security reasons.
