# compute_payroll

PAID ($0.10). Gross-to-net take-home pay for Nigeria or Kenya: applies PAYE (on the verified brackets) plus the statutory employee deductions (Nigeria: pension/NHF/NHIS; Kenya: NSSF/SHIF/Affordable Housing Levy) and reliefs, returning net pay with full workings, per-contribution citations and DISCLOSED assumptions. Nigeria's pension base needs pay composition — pass basic/housing/transport for an exact figure, or a market-convention 40/30/10 split is assumed and disclosed. Pass api_key if you have one; otherwise the response explains how to pay via x402.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "compute_payroll",
    "arguments": {
      "gross": 0,
      "country": "<country>"
    }
  }
}
```

## Why compute_payroll is rated Low

Even though compute_payroll 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.

Risk signals: Handles credentials or secrets (api_key) · High parameter count (12 properties)

## Use case

AI agents call compute_payroll to retrieve information from Reference Data without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Reference Data:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "compute_payroll": {}
  }
}
```
