equinox-checker · Equinox MCP Server MCP: Risk & Policy

WHAT IT DOES

What equinox-checker does on Equinox MCP Server

AI agents invoke equinox-checker to trigger actions in Equinox 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 equinox-checker needs a policy

The tool analyzes code and suggests fixes, which implies running a code validation or static analysis process. This falls under Execute as it triggers an external operation (code analysis engine) whose effects depend on the code arguments provided. It does not merely read stored data, nor does it write, delete, or move money.

From the tool's definition 'Analyze Equinox module code and suggest fixes' — the tool processes and runs analysis on code, which constitutes execution of an analytical/validation process against code inputs.
