Payroll Engine MCP Tools

Part of the Payroll Engine open-source payroll automation framework. Full documentation at payrollengine.org.

Read-only MCP tools for the Payroll Engine — HR, Payroll, Report and System query tools built on PayrollEngine.Mcp.Core, ready for use in any MCP server deployment.

NuGet Package

Available as a private GitHub Package:

dotnet add package PayrollEngine.Mcp.Tools

Overview

PayrollEngine.Mcp.Tools provides the complete set of read-only MCP tools that expose Payroll Engine data to AI agents. All tools are read-only by design — no mutations, no side effects, with two exceptions: get_employee_pay_preview and execute_payroll_report execute synchronous calculations without persisting anything to the database.

Tools are organized into four roles. Each role is independently enabled or disabled per server deployment via McpPermissions.

Tools

Server — Always Available

Registered unconditionally, independent of role permissions or isolation level.

Tool Description
get_server_info Server version, active isolation level, configured scope, and role permissions

HR — Human Resources

Employee master data, case values, and audit trail.

Tool Description
list_divisions List all divisions of a tenant
get_division Get a division by name
get_division_attribute Get a single custom attribute of a division
list_employees List employees with optional OData filter
get_employee Get an employee by identifier
get_employee_attribute Get a single custom attribute of an employee
list_employee_case_values Full case value history of an employee
list_company_case_values Company-level case values of a tenant
list_employee_case_changes Audit trail of employee data mutations
list_company_case_changes Audit trail of company data mutations

Payroll — Payroll Processing

Payroll structure, results, preview calculations, temporal case value queries, and lookup resolution.

Tool Description
list_payrolls List all payrolls of a tenant
get_payroll Get a payroll by name
list_payruns List all payruns of a tenant
list_payrun_jobs List all payrun jobs ordered by creation date descending
list_payroll_wage_types Effective wage types merged across all regulation layers

Assembly Marker

ToolsMarker is the assembly marker for tool discovery in ToolRegistrar.GetPermittedTypes():

var toolsAssembly = typeof(ToolsMarker).Assembly;
var permittedTypes = ToolRegistrar.GetPermittedTypes(toolsAssembly, permissions, isolationLevel);

When building a server that combines these tools with additional write tools from a private assembly, pass both assemblies to GetPermittedTypes or call it twice.

Repository Description
PayrollEngine.Mcp.Core Core infrastructure — ToolBase, isolation model, permission system
PayrollEngine.Mcp.Server Hosted MCP server using Core and Tools
PayrollEngine.Client.Core Payroll Engine REST API client
