AI agents call list_templates to retrieve information from IOX Cloud without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves informational data about available templates for deployment. It has no side effects, does not modify data, execute code, delete resources, or create financial obligations. The blast radius of misuse is minimal—an agent could only enumerate templates it is already authorized to see.
From the tool's definition Tool name 'list_templates' and description 'List available MCP server starter templates' indicate a read-only retrieval operation that queries and enumerates available templates without modifying state.
Attacks that exploit this kind of access
List available MCP server starter templates (database, API wrapper, scraper, etc.) you can deploy on IOX Cloud. It is categorised as a Read tool in the IOX Cloud MCP Server, which means it retrieves data without modifying state.
Register the IOX Cloud MCP server in PolicyLayer and add a rule for list_templates: 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 IOX Cloud. Nothing to install.
list_templates 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 list_templates 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 list_templates. 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.
list_templates is provided by the IOX Cloud MCP server (meruada/iox-cloud-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
