WHAT IT DOES

What v_txt2hex does on Hyperion

AI agents call v_txt2hex to retrieve information from Hyperion without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why v_txt2hex is rated Low

Even though v_txt2hex only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

RECOMMENDED RULE

The rule that runs v_txt2hex safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Hyperion, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For v_txt2hex, this is the rule to start with:

v_txt2hex Allowed

v_txt2hex 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": {
    "v_txt2hex": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect Hyperion, apply this rule, and every v_txt2hex call is checked against it from then on.
