get_credentials_oidc
AI agents call get_credentials_oidc to retrieve information from Looker MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'get' prefix strongly suggests this is a retrieval tool that queries or fetches OIDC credentials configuration data without modifying system state. While credentials data is sensitive, the read-only nature places it in the Read category.
From the tool's definition Tool name 'get_credentials_oidc' contains 'get', which indicates a retrieval operation rather than modification or execution. The description is empty, limiting confidence.
