How It Works
This extension is a thin wrapper that registers the @jarahkon/hass-mcp-server npm package as an MCP server via VS Code's mcpServerDefinitionProviders API. The actual MCP server runs as a child process using npx.
Sensitive credentials (access token, SSH password) are stored using VS Code's built-in SecretStorage API, ensuring they are encrypted at rest.
