WHAT IT DOES

What base_convert does on TinyFn

AI agents call base_convert 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.

Parameter	Type	Required	Description
`number`	string	Yes	Number to convert
`to_base`	integer	Yes	Target base
`from_base`	integer	Yes	Source base

Parameters from the server's own tool schema.

RISK

Why base_convert is rated Low

This tool performs a pure mathematical conversion between numerical bases (e.g., binary, decimal, hex). It is purely deterministic and read-only with no side effects, no data modification, and no external operations.

RECOMMENDED RULE

The rule that runs base_convert 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 base_convert, this is the rule to start with:

base_convert Allowed

base_convert 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": {
    "base_convert": {}
  }
}

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 base_convert call is checked against it from then on.
