WHAT IT DOES

What random_password does on TinyFn

AI agents call random_password 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
`count`	integer	—	Number of passwords to generate
`length`	integer	—	Password length
`numbers`	boolean	—	Include numbers
`symbols`	boolean	—	Include symbols
`lowercase`	boolean	—	Include lowercase letters
`uppercase`	boolean	—	Include uppercase letters
`exclude_ambiguous`	boolean	—	Exclude ambiguous characters (0O1lI)

Parameters from the server's own tool schema.

RISK

Why random_password is rated Low

Even though random_password 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 random_password 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 random_password, this is the rule to start with:

random_password Allowed

random_password 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": {
    "random_password": {}
  }
}

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 random_password call is checked against it from then on.
