WHAT IT DOES

What validate_date does on TinyFn

AI agents call validate_date 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
`format`	string	—	Expected date format
`date_str`	string	Yes	Date string to validate

Parameters from the server's own tool schema.

RISK

Why validate_date is rated Low

Validation tools perform read-only checks on supplied inputs and return boolean or error results with no side effects. This is a deterministic utility tool from a math/conversion/validation suite with no capacity to execute external operations, modify data, or cause financial impact. Misuse would not create meaningful harm.

From the tool's definition Tool name 'validate_date' and description 'Validate a date string' indicate a validation/query operation that checks input without modifying, creating, or deleting data.

RECOMMENDED RULE

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

validate_date Allowed

validate_date 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": {
    "validate_date": {}
  }
}

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 validate_date call is checked against it from then on.
