Use this when ChatGPT should render the authenticated user
AI agents call identity.profile_card to retrieve information from GPT MCP Service without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and renders profile information for an already-authenticated user. It is a read-only operation that queries user identity data without side effects, data modification, or execution of commands. The narrow scope (authenticated user only) and informational nature keep severity low.
From the tool's definition Tool description states it 'render[s] the authenticated user' - a display/retrieval operation with no modification or execution of external actions.
Attacks that exploit this kind of access
Use this when ChatGPT should render the authenticated user. It is categorised as a Read tool in the GPT MCP Service MCP Server, which means it retrieves data without modifying state.
Register the GPT MCP Service MCP server in PolicyLayer and add a rule for identity.profile_card: 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 GPT MCP Service. Nothing to install.
identity.profile_card 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.profile_card 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.profile_card. 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.profile_card is provided by the GPT MCP Service MCP server (jmillpps/encore-mcp-base). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
