WHAT IT DOES

What token-info does on Mcp Test Servers

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

RISK

Why token-info is rated Low

This tool retrieves or queries existing data (token expiration information) with no side effects or ability to modify, delete, or execute operations. It is a straightforward informational read operation, representing minimal security risk even if accessed by an unauthorized actor, as it only exposes token metadata.

From the tool's definition Tool name 'token-info' and description 'Returns information about the current access token expiration' indicate a retrieval operation that queries token metadata without modifying or executing any operations.

RECOMMENDED RULE

The rule that runs token-info safely

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

token-info Allowed

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

  "tools": {
    "token-info": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Test Servers, apply this rule, and every token-info call is checked against it from then on.
