Scored across 44 tools
Many tools overlap in purpose, such as the multiple planning tools (generate_tax_plan, get_tax_planning_tips, plan_multi_year_taxes) and the comparison tools (compare_filing_statuses vs compare_mfj_vs_mfs, compare_state_taxes vs analyze_relocation_taxes). While descriptions are detailed, the sheer number of similar-sounding tools creates selection ambiguity.
The naming is mostly consistent with verb_noun snake_case (calculate_federal_tax, list_deductions, estimate_state_tax). A few outliers like standard_vs_itemized and what_changed_between_tax_years break the pattern, but overall it's predictable and readable.
With 44 tools, this server is heavily over-scoped. While the tax domain is broad, this number exceeds reasonable limits (25+ is considered too many) and makes the tool list unwieldy, increasing selection overhead for agents.
The surface covers federal and state taxes, credits, deductions, retirement, planning, forms, deadlines, and scenario simulation. Minor gaps exist (e.g., actual form filing) but core workflows are well-covered, making it near-complete for a tax advisory MCP.
