corrosion_get_server_info
AI agents call corrosion_get_server_info to retrieve information from Corrosion Engineering MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool appears to retrieve or query server information with no side effects. It fits the 'Read' category as a lookup/metadata retrieval operation. Severity is low because server info retrieval poses minimal risk to data integrity or system state—even if an AI agent calls it, the impact is confined to information disclosure about the service itself.
From the tool's definition Tool name 'corrosion_get_server_info' indicates retrieval of metadata or configuration information about the server. The 'get_' prefix and 'server_info' suffix strongly suggest a read-only lookup operation.
