lint_javascript_code · MCP SAPUI5 Server MCP: Risk & Policy

WHAT IT DOES

What lint_javascript_code does on MCP SAPUI5 Server

AI agents invoke lint_javascript_code to trigger actions in MCP SAPUI5 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 lint_javascript_code needs a policy

This tool executes linting operations on JavaScript code. While linting itself is generally non-destructive (read-only analysis), ESLint engines execute code parsing and rule evaluation logic. The tool's effects depend on the code being analyzed—it could identify security issues, performance problems, or other code quality concerns.

From the tool's definition Tool runs ESLint-style static checks, which involves executing a linting engine against code. The description explicitly states it 'runs' checks and returns suggested fixes, indicating code execution.
