What problem does it solve?
Founders waste time re-explaining tax rules to a chatbot or bouncing between spreadsheets when they only need fast, structured US tax estimates inside their agent session.
Who is it for?
US-based solo builders who want agent-driven tax what-ifs and deduction checks during operate-phase financial planning.
Skip if: Non-US tax, enterprise payroll, or anyone who needs certified filing software instead of exploratory MCP tools.

- Agent-callable answers across 39 tax-related MCP tools
- Local execution path for federal/state, credits, deductions, and retirement prompts
Recommended MCP Servers
Journey fit
Tax planning and filing sit in the run-the-business loop after you are earning—not in ideation or launch mechanics. Iterate covers recurring financial decisions (estimated payments, deduction checks, year-end what-ifs) that solo founders revisit each season.
How it compares
MCP integration for local tax calculators, not an agent skill or a full TurboTax-style filing product.
