I Hoped Spending Less Would Solve It. The Data Said Otherwise.

I Hoped Spending Less Would Solve It. The Data Said Otherwise.

Short summary

The author built PlaidMCP, a local MCP server, to let Claude analyze five years of personal spending data instead of using spreadsheets or traditional budgeting apps. Claude's analysis revealed the real problem wasn't excessive spending but a timing/clustering of bill payments and insufficient income. The insight confirmed a difficult truth the author already sensed: career growth and secondary income matter more than spending cuts.

  • •Built custom MCP server to expose financial data to Claude
  • •Analysis revealed income mismatch, not overspending
  • •Confirmed need for career change over expense cutting
