MCP Servers

Jan supports the Model Context Protocol (opens in a new tab), letting you connect any MCP-compatible server to extend what your AI can do — web search, browser control, code execution, databases, and more.

MCP Servers Settings

Settings

  • Allow All MCP Tool Permissions — When enabled, all MCP tool calls are automatically approved without showing permission dialogs. Applies globally to all conversations.
  • Tool call timeout — Maximum time (in seconds) to wait for an MCP tool response before timing out. Default is 30 seconds.

Add an MCP Server

Open Settings

Go to Settings → MCP Servers.

Add server

Click + Add MCP Server in the top right corner.

Configure

Enter the server details:

  • Transport: STDIO (local process), HTTP (Streamable HTTP), or SSE (Server-Sent Events)
  • Command / URL: the command to run or the server endpoint
  • Args: any arguments to pass
  • Env: environment variables (e.g. API keys)

Enable

Toggle the server on. It will appear in the list with a green indicator when active.
