lookup_unicode
Get Unicode info for a character or codepoint (name, category, hex). Use for text-processing and emoji-debugging agents. Example call: {"char_or_code": "U+1F600"} Cost: $0.005–$0.05 USDC on Base per call.

What lookup_unicode does on GoCreative Agent API
AI agents call lookup_unicode 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 |
|---|---|---|---|
char_or_code | string | Yes |
Parameters from the server's own tool schema.
Why lookup_unicode is rated Low
This tool performs a pure query/lookup operation against Unicode data with no side effects. It cannot modify, execute, delete, or conduct financial operations. The pay-per-call model is irrelevant to functional risk classification. Severity is low because misuse by an AI agent cannot cause harm beyond potentially wasting API credits on excessive calls.
From the tool's definition Tool retrieves Unicode metadata ('name, category, hex') for a given character or codepoint. The example call shows a simple lookup operation with no mutation capability.
Attacks that exploit this kind of access
The rule that runs lookup_unicode 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_unicode, this is the rule to start with:
lookup_unicode 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_unicode call is checked against it from then on.
Questions about lookup_unicode
Get Unicode info for a character or codepoint (name, category, hex). Use for text-processing and emoji-debugging agents. Example call: {"char_or_code": "U+1F600"} 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_unicode accepts 1 parameter: char_or_code. Required: char_or_code. 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_unicode: 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_unicode 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_unicode 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_unicode. 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_unicode 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.
