Check for software updates — what version you
AI agents call rivian_get_ota_status to retrieve information from Rivian MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries OTA (over-the-air) update status and version information. It performs a read operation with no side effects—it retrieves data but does not modify, execute, delete, or commit financial transactions. The incomplete description appears to be a truncation but context from sibling tools and server description confirms read-only semantics.
From the tool's definition Tool name is 'rivian_get_ota_status' and description indicates it 'Check[s] for software updates — what version you' (description cuts off).
