WHAT IT DOES

What ipv6_to_ipv4 does on TinyFn

AI agents call ipv6_to_ipv4 to retrieve information from TinyFn without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why ipv6_to_ipv4 is rated Low

This is a deterministic data transformation utility that reads an input (IPv6 address) and outputs a derived value (extracted IPv4 address). It has no capability to modify, delete, execute code, or affect external systems. It belongs in the Read category as a data query/extraction tool.

From the tool's definition Tool name 'ipv6_to_ipv4' and description 'Extract IPv4 address from IPv6 mapped address' indicate a data retrieval/transformation operation with no side effects. It parses and extracts information from an IPv6 address.

RECOMMENDED RULE

The rule that runs ipv6_to_ipv4 safely

PolicyLayer is an MCP gateway: it sits between your AI agents and TinyFn, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For ipv6_to_ipv4, this is the rule to start with:

ipv6_to_ipv4 Allowed

ipv6_to_ipv4 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": {
    "ipv6_to_ipv4": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect TinyFn, apply this rule, and every ipv6_to_ipv4 call is checked against it from then on.
