WHAT IT DOES

What whoami does on Postking Mcp

AI agents call whoami to retrieve information from Postking Mcp 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 only reads and returns information about the authenticated user. It performs no writes, executions, or destructive actions. The data returned (email, plan, credit balance, token source) is informational only. Misuse potential is minimal — an attacker could learn the user's email or plan tier, but cannot cause harm beyond information disclosure.

From the tool's definition 'Return the profile of the currently authenticated PostKing user (email, plan, credit balance, token source)' — purely retrieves user profile data with no side effects

RECOMMENDED RULE

The rule that runs whoami safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Postking Mcp, 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 Postking Mcp, apply this rule, and every whoami call is checked against it from then on.
