Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Travel per diem allowances. It covers bundled daily allowance rates with their authority, source and effective date, a trip's allowance with partial days and meal deductions, saved trips with the traveller taken from the shared business profile, and saved trips turned into expense entries for the expense tracker. Saved trips are stored per user account on McpStamp's hosted service. Rate lookups and calculations are free and unlimited; the free tier saves 5 trips a month, and expense export and monthly totals need Pro. One lifetime key unlocks this server and all 58 others: https://mcp.zovo.one/buy/bundle?src=instr.per-diem
