Test results
Safe mode: only tools labeled read-only were run. How the test works
- !Ready for the newest MCP versionnote
1 warning
- !Uses an older MCP version (2025-11-25). It works today, but it isn't on the July 2026 version (2026-07-28) yet.
- !Tools are labeled safe or dangerousnote
1 warning
- !8 of 8 tools have no safety label (read-only or dangerous): list_tax_years, tax_rates, inflation, student_loan_repayment, child_care_subsidy, government_spending, compare_income, calculate_pay
- !Follows MCP best practices (not scored yet)note
3 tips (not scored)
- !8 tools not labeled read-only don't say whether running them twice is safe (idempotentHint): list_tax_years, tax_rates, inflation, student_loan_repayment, child_care_subsidy, government_spending and 2 more
- !8 tools don't say whether they reach outside services like the web (openWorldHint): list_tax_years, tax_rates, inflation, student_loan_repayment, child_care_subsidy, government_spending and 2 more
- !The tool list is about 66 KB (roughly 17k tokens). AI apps send it with every message, so it takes that much of the AI's memory before any work starts.
