Can I visualize my financial projections?

Yes, the skill can generate self-contained HTML dashboards and Chart.js specifications for fan charts, account breakdowns, and scenario comparisons.

Where is my financial data stored?

FinPlan uses client-side state persistence. Financial profiles, accounts, and goals are saved locally to a JSON file on your machine, ensuring privacy and continuity between sessions.

What happens if the MCP connection fails?

FinPlan includes a diagnostic command (/finplan:diagnose) that tests server reachability, authentication, and tool availability to help you troubleshoot connection issues.

Does FinPlan support US-specific tax calculations?

Yes, it includes specialized tools for modeling US federal income tax, capital gains, and after-tax projections based on current tax logic.

How does FinPlan handle large financial datasets?

FinPlan uses a file-based response system that writes full results to a file server, returning only URLs and summaries to Claude. This prevents large time-series data from overwhelming the LLM context window.
