Why cmyk_to_rgb_tool needs a policy

This tool retrieves or computes color values based on input parameters. It does not create, modify, delete, or execute any operations. It is a pure read/compute operation typical of color management utilities. The offline nature and lack of API keys confirm no external state changes occur. Severity is low because misuse causes only cosmetic/formatting issues in color output.

From the tool's definition Tool performs color space conversion from CMYK to RGB/HEX values. The description indicates it 'converts' values with no modification of data or execution of external operations. This is a stateless computational lookup/transformation with no side effects.

POLICY

How to control cmyk_to_rgb_tool

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Print, and nothing reaches the server without passing your rules. This is the rule we recommend for cmyk_to_rgb_tool:

policy.json

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

cmyk_to_rgb_tool is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Mcp Print — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about cmyk_to_rgb_tool

What does the cmyk_to_rgb_tool tool do? +

Convert CMYK values to RGB and HEX. It is categorised as a Read tool in the Mcp Print MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on cmyk_to_rgb_tool? +

Register the Mcp Print MCP server in PolicyLayer and add a rule for cmyk_to_rgb_tool: 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 Mcp Print. Nothing to install.

What risk level is cmyk_to_rgb_tool? +

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

Can I rate-limit cmyk_to_rgb_tool? +

Yes. Add a rate_limit block to the cmyk_to_rgb_tool 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 cmyk_to_rgb_tool completely? +

Set action: deny in the PolicyLayer policy for cmyk_to_rgb_tool. 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 cmyk_to_rgb_tool? +

cmyk_to_rgb_tool is provided by the Mcp Print MCP server (kcgdz/mcp-print). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Mcp Print tool call.

Start from Mcp Print, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
