Bring your own tools to your Double.

Tools in The Double run on MCP, the open standard for connecting AI to apps. So the MCP server you build or already use can become a tool for your Double too.

  • The actions your MCP server exposes
  • Per-action permissions, like every tool
  • Sensitive actions wait for your OK

For every action you choose who can trigger it (nobody, only you, or you and visitors) and whether it asks first. Destructive actions stay locked.

You might have some questions

What is an MCP tool?

MCP (Model Context Protocol) is an open standard that lets AI use apps. An MCP server exposes actions; connected to your Double, those actions become a tool.

How is this different from the MCP page?

The MCP page is about running your Double from ChatGPT or Claude. This page is the other direction: your Double using your own MCP tools.

Do the same permissions apply?

Yes. You choose what your Double may do with each action, and sensitive actions wait for your OK.

Do I need to build a server?

Only if your tool doesn’t have one yet. Many apps already publish an MCP server.

Extend your Double with your own tools.

Build your Double, then connect your MCP server.
