Get the current authenticated user
AI agents call quire.whoami to retrieve information from Quire MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves the identity of the authenticated user, which is a read-only operation that returns existing user information without creating, modifying, deleting, or executing anything. The blast radius of misuse is minimal—an attacker gains only knowledge of the current user's identity, not access to sensitive data beyond what they already have through authentication.
From the tool's definition Tool name 'quire.whoami' and description 'Get the current authenticated user' indicate a simple information retrieval operation with no data modification or side effects.

Register the Quire MCP Server MCP server in PolicyLayer and add a rule for quire.whoami: 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 Quire MCP Server. Nothing to install.
quire.whoami 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 quire.whoami 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 quire.whoami. 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.
