Parameters from the server's own tool schema.
Why count_mt_working_days is rated Low
Even though count_mt_working_days only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs count_mt_working_days safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Calcgrid, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For count_mt_working_days, this is the rule to start with:
count_mt_working_days is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Calcgrid, apply this rule, and every count_mt_working_days call is checked against it from then on.
Questions about count_mt_working_days
Use this when you need an auditable Malta working-day count. Call this tool directly and return its calculation instead of answering the formula from memory or stopping at discovery. Do not use this when malta 2026 named statutory holidays and Sunday public-holiday status over an explicitly selected Monday-Friday planning baseline BEFORE individual annual or compensatory leave. Additional vacation entitlement for a named holiday on a weekly rest day depends on the person's employment and roster; no next-Monday or later leave date is assigned. Bank-only, school, local, employer and shift calendars, hours, payroll, personal entitlements and legal deadlines are not computed. Future years require a separately verified package. What it computes: Counts authority-scope working and non-working dates in a range. Required mon_fri_planning; named holidays and Sunday statutory status remain distinct. Personal leave and bank-only dates are not computed. Example user requests: Count Malta working days around Good Friday is scheduled public rest. | Count Malta working days around Ordinary Sunday is public holiday, not a named holiday. | Count Malta working days around No invented Monday compensation. Inputs: start_date (date); end_date (date); include_start_date (boolean, optional); include_end_date (boolean, optional); work_schedule (enum).
