unbilled_report · ERP-File MCP Server MCP: Risk & Policy

WHAT IT DOES

What unbilled_report does on ERP-File MCP Server

AI agents call unbilled_report to retrieve information from ERP-File MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

WHY IT NEEDS A POLICY

Why unbilled_report needs a policy

Report generation tools that query ERP data without modifying it fall under the 'Read' category. The lack of 'delete', 'update', 'create', or 'execute' language in the name, combined with sibling reporting tools being read-only operations, indicates this retrieves financial/business data for analysis. Low severity because misuse retrieves information rather than causing operational or financial damage.

From the tool's definition Tool name 'unbilled_report' suggests report generation/retrieval. Server description indicates this is an ERP data access system focused on 'querying' and 'accessing data'.
