WHAT IT DOES

What whoami does on Frontmcp

AI agents call whoami to retrieve information from Frontmcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why whoami is rated Low

This tool queries identity provider (IdP) token information for the authenticated user. It is a read-only operation that retrieves existing authentication data without creating, modifying, deleting, or executing external actions.

From the tool's definition Tool name 'whoami' and description 'Read the upstream IdP token via orchestration' explicitly uses the verb 'Read' and retrieves authentication token data without modification.

RECOMMENDED RULE

The rule that runs whoami safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Frontmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For whoami, this is the rule to start with:

whoami Allowed

whoami is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "whoami": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Frontmcp, apply this rule, and every whoami call is checked against it from then on.
