identity-oidc-role-read
AI agents call identity-oidc-role-read to retrieve information from Vault MCP Server (mschuchard) without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads OIDC identity role configuration from Vault without modifying state. Reading identity and authentication configurations is a Read operation with medium severity because OIDC role details may contain sensitive metadata about role bindings, claim mappings, or policy associations that could inform further attacks, but the operation itself causes no direct harm or state changes.
From the tool's definition Tool name 'identity-oidc-role-read' contains 'read', indicating data retrieval. Server context shows it interacts with HashiCorp Vault to manage authentication and identity systems.
