🟡 Tilde path expansion uses process.env.HOME instead of os.homedir() (packages/core/src/execution/mode.ts:100)

The PR description claims "Fixed tilde path expansion (use os.homedir())" but the code in detectMcpServers() still uses process.env.HOME for tilde expansion.

Click to expand

Issue

At line 100, the code expands tilde paths using:

const fullPath = configPath.startsWith('~')
  ? configPath.replace('~', process.env.HOME || '')
  : configPath;

On Windows, process.env.HOME is typically undefined, causing the tilde to be replaced with an empty string. This results in invalid paths like /.mcp.json instead of C:\Users\username\.mcp.json.

Expected Behavior

The code should use homedir() (which is already imported at line 5) for cross-platform compatibility:

const fullPath = configPath.startsWith('~')
  ? configPath.replace('~', homedir())
  : configPath;

Impact

Windows users passing custom MCP config paths with tilde (e.g., ~/.mcp.json) will have those paths incorrectly resolved, causing MCP server detection to silently fail. The default paths at lines 40-44 correctly use join(homedir(), ...) so the impact is limited to custom configurations.

Recommendation: Replace process.env.HOME || '' with homedir() to ensure cross-platform compatibility, matching the approach used for DEFAULT_MCP_CONFIG_PATHS at lines 40-41.
