identity-entities-list
AI agents call identity-entities-list 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.
The tool name pattern and server context (Vault ACL/secret management) indicate this retrieves a list of identity entities, which is a read operation with no side effects. Severity is medium rather than low because identity entity information in Vault could include sensitive metadata about principals and their permissions, which could inform reconnaissance attacks.
From the tool's definition Tool name 'identity-entities-list' and context of a Vault MCP server indicate a query/list operation for retrieving identity entities. The '-list' suffix strongly suggests data retrieval without modification.

identity-entities-list. It is categorised as a Read tool in the Vault MCP Server (mschuchard) MCP Server, which means it retrieves data without modifying state.
Register the Vault MCP Server (mschuchard) MCP server in PolicyLayer and add a rule for identity-entities-list: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Vault MCP Server (mschuchard). Nothing to install.
identity-entities-list is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the identity-entities-list rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for identity-entities-list. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
identity-entities-list is provided by the Vault MCP Server (mschuchard) MCP server (mschuchard/vault-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
