What lookup_color_palette does on GoCreative Agent API
AI agents call lookup_color_palette to retrieve information from GoCreative Agent API 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 |

seed_hex | string | Yes |
Parameters from the server's own tool schema.
Why lookup_color_palette is rated Low
This is a pure computation tool that takes a hex color input and returns derived color values. It has no side effects, does not modify data, does not execute arbitrary code, and does not access sensitive systems. The output is deterministic and reversible (the same seed always produces the same palette).
From the tool's definition Tool generates and returns a color palette from a seed hex code with no modification of external state. Description explicitly states 'Generate a complementary color palette' and example shows input-only operation with computational output.
Attacks that exploit this kind of access
The rule that runs lookup_color_palette safely
PolicyLayer is an MCP gateway: it sits between your AI agents and GoCreative Agent API, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For lookup_color_palette, this is the rule to start with:
lookup_color_palette is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect GoCreative Agent API, apply this rule, and every lookup_color_palette call is checked against it from then on.
Questions about lookup_color_palette
Generate a complementary color palette from a seed hex code. Use for design agents and theme generators. Example call: {"seed_hex": "3b82f6"} Cost: $0.005–$0.05 USDC on Base per call. It is categorised as a Read tool in the GoCreative Agent API MCP Server, which means it retrieves data without modifying state.
lookup_color_palette accepts 1 parameter: seed_hex. Required: seed_hex. The full parameter table on this page comes from the server's own tool schema.
Register the GoCreative Agent API MCP server in PolicyLayer and add a rule for lookup_color_palette: 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 GoCreative Agent API. Nothing to install.
lookup_color_palette 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 lookup_color_palette 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 lookup_color_palette. 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.
lookup_color_palette is provided by the GoCreative Agent API MCP server (https://api.gocreativeai.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
