AI agents call who_am_i to retrieve information from Mycase without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation that retrieves existing profile data about the authenticated user. It has no side effects, does not modify data, and does not execute external operations. The blast radius of misuse is minimal—an attacker could only learn who is currently authenticated. Classification as Read is appropriate.
From the tool's definition Tool retrieves 'the currently authenticated staff member's profile' with no modification capability indicated. This is a simple query operation returning user identity information.
Attacks that exploit this kind of access
Get the currently authenticated staff member's profile. It is categorised as a Read tool in the Mycase MCP Server, which means it retrieves data without modifying state.
Register the Mycase MCP server in PolicyLayer and add a rule for who_am_i: 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 Mycase. Nothing to install.
who_am_i 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 who_am_i 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 who_am_i. 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.
who_am_i is provided by the Mycase MCP server (rosenadvertising/mycase-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
