WHAT IT DOES

What poll_device_token does on instantKOM MCP Server

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

RISK

Why poll_device_token is rated Low

Polling for a device authorization token is a read/query operation that checks the status of an ongoing device flow. However, it has moderate severity because it's part of an authentication flow — if misused, it could be used to complete unauthorized device authorization, potentially granting access to accounts. The tool itself only retrieves/checks status rather than modifying state.

RECOMMENDED RULE

The rule that runs poll_device_token safely

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

poll_device_token Allowed

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

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

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