CALL WHEN confused about CodeModeTOON. Returns step-by-step guides for quickstart, troubleshooting, and best practices.
AI agents call usage_guide to retrieve information from Code Mode Toon without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays informational content (guides, troubleshooting, best practices) to help users understand and use the system. It is a pure Read operation: it queries internal documentation and returns data without creating, modifying, executing code, or destroying anything. The low severity reflects that misuse would only result in a user reading irrelevant documentation, with no blast radius.
From the tool's definition Tool name 'usage_guide' and description states it 'Returns step-by-step guides' - a retrieval operation that provides documentation/help information with no side effects.
Documented attack patterns abuse exactly the kind of access usage_guide gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Code Mode Toon, and nothing reaches the server without passing your rules. This is the rule we recommend for usage_guide:
{
"version": "1",
"default": "deny",
"tools": {
"usage_guide": {}
}
}usage_guide is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

CALL WHEN confused about CodeModeTOON. Returns step-by-step guides for quickstart, troubleshooting, and best practices. It is categorised as a Read tool in the Code Mode Toon MCP Server, which means it retrieves data without modifying state.
Register the Code Mode Toon MCP server in PolicyLayer and add a rule for usage_guide: 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 Code Mode Toon. Nothing to install.
usage_guide 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 usage_guide 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 usage_guide. 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.
usage_guide is provided by the Code Mode Toon MCP server (ziad-hsn/code-mode-toon). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Code Mode Toon, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
