{

      "args": []
    }
  }
}

You run an MCP server that generates passwords using a dedicated opgen backend and automatically copies the generated password to your clipboard. This lets you request new passwords from an MCP client and receive a ready-to-use password without manual copying.

How to use

To generate passwords through an MCP client, start the opgen MCP server locally using either the prebuilt binary or a Go run command. Once the server is running, configure your MCP client to connect via the chosen method and request password generation. The server exposes two password generation tools: one that creates a string of random characters and another that builds passwords from word sequences. Each request returns a password and copies it to your clipboard for immediate use.

How to install

Prerequisites: you need a Go development environment installed on your machine.

GO111MODULE=on
# Install the opgen MCP server binary
go install github.com/syumai/opgen-mcp-server@latest

Configuration and usage notes

The MCP server can be run in two ways. Use whichever you prefer for your workflow.

{
  "opgen": {
    "command": "opgen-mcp-server"
  }
}

{
  "opgen": {
    "command": "go",
    "args": ["run", "github.com/syumai/opgen-mcp-server@latest"]
  }
}
