affinity_run_macro · Affinity MCP Server MCP: Risk & Policy

WHAT IT DOES

What affinity_run_macro does on Affinity MCP Server

AI agents invoke affinity_run_macro to trigger actions in Affinity 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 affinity_run_macro needs a policy

This tool executes external macro files whose behavior is determined by the macro's contents. While not as severe as Destructive (macros could delete files or perform irreversible operations, making this borderline), the primary risk is uncontrolled code execution within the Affinity application context.

From the tool's definition Tool description states 'Import and run an .afmacro file' — the "run" verb indicates execution of arbitrary code/macros.
