[Bug]

Describe the bug

Running openbb-mcp-server via uvx fails immediately after startup with an uninformative error — the actual exception message is not printed, only a bare "Server error:" label.

To Reproduce

1. uvx --from openbb-mcp-server --with openbb openbb-mcp --transport stdio
2. Server logs "Loaded bundled skills..." and "Added default system prompt with skill awareness nudge."
3. Immediately after, logs ERROR Server error: (app.py:1027) with no exception detail, and the process exits.

Environment

• OS: Windows
• Installed via: uvx (using uv)
• No ~/.openbb directory exists (fresh user, never configured)
• No ~/.openbb_platform/mcp_settings.json exists

What I've ruled out

• PATH issues — uvx.exe resolves correctly, confirmed via logs and manual terminal run
• Windows console encoding — set chcp 65001, PYTHONUTF8=1, PYTHONIOENCODING=utf-8; identical crash
• Corrupted/stale cached packages — ran uv cache clean (removed 23,391 files), reinstalled all 149 packages fresh in 3.92s; identical crash
• Corrupted local OpenBB config — no .openbb directory exists to be corrupted
• Reproducible identically both via uvx directly in a terminal and via Claude Desktop's MCP server launcher

Expected behavior

Either the server starts successfully, or — at minimum — the actual exception (type + message + traceback) should be logged instead of a bare "Server error:" with no detail. The current logging swallows the real cause, making this impossible to self-diagnose.

Additional context

Ran openbb-mcp --help — no --verbose or --log-level flag is exposed that would help surface the underlying exception.
