Installation

Use uv to manage the dependencies:

git clone ...
cd mcp-python-host_info
uv sync

For development, install test dependencies:

uv pip install -e ".[dev]"

# install the pacakge in development mode
uv pip install -e .

Running Tests

Run the test suite with coverage report:

pytest

This will:

• Run all tests in the tests/ directory
• Generate a coverage report for the host_info package
• Show missing lines in the coverage report

Test files are organized to mirror the package structure:

• test_tools.py: Tests for host information gathering functionality
• test_main.py: Tests for MCP server setup and configuration

Debug/Development

Run the MCP server:

uv run python src/main.py

Debug the MCP server:

uv add "mcp[cli]"
uv run mcp dev src/main.py
