Skill Management MCP Server

Execute a script or executable program within a skill directory with optional arguments and automatic dependency management.

This tool runs scripts in multiple languages and automatically manages dependencies:

SUPPORTED LANGUAGES:

• Python: Automatically installs PEP 723 inline dependencies via 'uv run' if declared in the script

• Bash: Executes shell scripts (.sh files)

• Other: Any executable file with proper shebang line

FEATURES:

• Automatic dependency installation: Python scripts with PEP 723 metadata (/* script */ dependencies) are run with 'uv run' automatically

• Environment variables: Loads skill-specific .env file and injects variables into script environment

• Working directory: Can specify a subdirectory to run the script from

• Arguments: Pass command-line arguments to the script

• Output capture: Returns stdout, stderr, and exit code

PARAMETERS:

• skill_name: The name of the skill directory (e.g., 'weather-skill')

• script_path: Relative path to the script (e.g., 'scripts/fetch_weather.py', 'bin/process.sh')

• args: Optional list of command-line arguments to pass to the script (e.g., ['--verbose', 'input.txt'])

• working_dir: Optional working directory for execution (relative to skill root)

BEHAVIOR:

• Python scripts with PEP 723 metadata are detected automatically and run with 'uv run'

• Environment variables from skill's .env file are available to the script

• Script must be executable or have proper shebang line

• Script path is relative to the skill directory

RETURNS: Script execution result with:

• Exit code (0 = success, non-zero = failure)

• STDOUT (standard output)

• STDERR (error output)
