Parameters from the server's own tool schema.
This tool performs a stateless color blending calculation with no side effects on any system, database, or external service. It is a read-like operation in the sense that it retrieves a computed result based on inputs without altering any state. The minimal blast radius and lack of any destructive, executable, or financial capability warrant a 'low' severity classification.
From the tool's definition Tool name 'color_mix' and description 'Mix two colors together' indicate a pure computational operation that takes two color inputs and returns a blended result. No data creation, modification, deletion, code execution, or financial transactions are involved.

Register the UnClick MCP server in PolicyLayer and add a rule for color_mix: 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 UnClick. Nothing to install.
color_mix is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the color_mix 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.
Set action: deny in the PolicyLayer policy for color_mix. 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.
color_mix is provided by the UnClick MCP server (@unclick/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
