WHAT IT DOES

What saturate_color does on TinyFn

AI agents call saturate_color 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
`amount`	integer	—	Amount to saturate (0-100)
`hex_color`	string	Yes	Hex color to saturate

Parameters from the server's own tool schema.

RISK

Why saturate_color is rated Low

This tool performs a deterministic computation on a color value, returning a modified color representation. It reads input, computes a result, and returns it without modifying any external state. Consistent with the server's described purpose of 500+ deterministic tools.

From the tool's definition Increase color saturation by a percentage — pure deterministic transformation, no side effects

RECOMMENDED RULE

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

saturate_color Allowed

saturate_color 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": {
    "saturate_color": {}
  }
}

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 saturate_color call is checked against it from then on.

FAQ

Questions about saturate_color

What does the saturate_color tool do? +

Increase color saturation by a percentage. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.

What parameters does saturate_color accept? +

saturate_color accepts 2 parameters: amount, hex_color. Required: hex_color. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on saturate_color? +

Register the TinyFn MCP server in PolicyLayer and add a rule for saturate_color: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches TinyFn. Nothing to install.

What risk level is saturate_color? +

saturate_color is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit saturate_color? +

Yes. Add a rate_limit block to the saturate_color rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block saturate_color completely? +

Set action: deny in the PolicyLayer policy for saturate_color. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides saturate_color? +

saturate_color is provided by the TinyFn MCP server (https://api.tinyfn.io/mcp/all/). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
