WHAT IT DOES

What generate_shades does on TinyFn

AI agents call generate_shades 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 shades
`hex_color`	string	Yes	Base hex color

Parameters from the server's own tool schema.

RISK

Why generate_shades is rated Low

This tool performs a read/compute operation, generating darker color variations from an input color. It is purely deterministic with no data modification, execution, or financial implications. Misuse has negligible impact.

RECOMMENDED RULE

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

generate_shades Allowed

generate_shades is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

{
  "version": "1",
  "default": "deny",
  "tools": {
    "generate_shades": {}
  }
}

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 generate_shades call is checked against it from then on.
