run_report · ERPNext MCP Server MCP: Risk & Policy

WHAT IT DOES

What run_report does on ERPNext MCP Server

AI agents invoke run_report to trigger actions in ERPNext MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why run_report needs a policy

This tool triggers execution of business logic (report generation) whose behavior and output depend entirely on arguments passed to it. While reports are typically read-oriented, the tool itself executes a predefined operation that could have side effects depending on the report definition (e.g., reports that log access, trigger workflows, or modify data).

From the tool's definition Tool name 'run_report' combined with description 'Run an ERPNext report' indicates execution of a pre-defined report operation.
