WHAT IT DOES

What run_code_and_show_plot does on Financial Analyst MCP Server

AI agents invoke run_code_and_show_plot to trigger actions in Financial Analyst 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_code_and_show_plot needs a policy

This tool executes Python code with side effects that depend on the code's contents. While the immediate effect (plotting) appears benign, executing code files is an Execute-category action with high severity due to the potential for AI agents to be tricked into running malicious or unintended code.

From the tool's definition Tool name contains 'run_code' and description states 'Run the code in stock_analysis.py', indicating execution of arbitrary Python code. Generating plots involves external operations dependent on code contents.
