upgrade_solactl · SOLAPI MCP Server MCP: Risk & Policy

WHAT IT DOES

What upgrade_solactl does on SOLAPI MCP Server

AI agents invoke upgrade_solactl to trigger actions in SOLAPI 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.
