Digital Calculator (Markcolabs) financial calculator MCP server: 14 read-only tools for mortgage, loan, compound interest, savings, inflation, 401(k), Social Security, paycheck, IRA, Roth conversion, RMD, HSA, and emergency-fund calculations, plus money_flow_map — build a monthly budget conversationally and get back a computed summary with a link to an interactive money-flow (Sankey) map. IMPORTANT: all results are educational estimates computed with deterministic formulas from the inputs provided — they are not financial, tax, legal, or investment advice; actual rates, fees, taxes, and outcomes vary by lender, jurisdiction, and personal circumstances, so verify with a licensed professional before making financial decisions. Units: all monetary inputs and outputs are USD; rates are whole-number percents (e.g., 6.5 means 6.5%). Resources: read dc://disclaimers/ymyl for the canonical YMYL disclaimer and dc://methodologies/manifest for per-tool methodology URLs.
