MCP Script Runner

Prerequisites

• python: e.g. mise install [email protected] && mise use [email protected] -g
• uv: e.g. brew install uv

Configure

git clone https://github.com/ktrysmt/mcp-script-runner
cd ./mcp-script-runner
uv sync

and add mcp.json to your mcp config like this:

{
  "mcpServers": {
    "mcp-script-runner": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/mcp-script-runner",
        "run",
        "main.py"
      ]
    }
  }
}

Change command dir:

{
  "mcpServers": {
    "mcp-script-runner": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/mcp-script-runner",
        "run",
        "main.py"
      ],
      "env": {
        "COMMAND_DIRECTORY": "/path/to/your/dir"
      }
    }
  }
}

Use dotenv:

cd ./mcp-script-runner
$EDITOR .env

Add a tool

cd ./mcp-script-runner
$EDITOR ./commands/command_name.sh

and reload the mcp.

Precautions

• Since files are executed directly, do not forget to include the shebang in each file.
• Execution permission is required for the files (although there is a process to adjust permissions included).
• This is intended for local use only, and only scripts that you understand should be placed here.
