List available video templates that can be used as starting points.
AI agents call list_templates to retrieve information from Hyper Video Service without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns a list of available templates. It performs no modifications, deletions, code execution, or financial transactions. It is a simple read operation that retrieves information from the server's template inventory. The blast radius of misuse is minimal—an agent could only enumerate templates, which poses no security or operational risk.
From the tool's definition Tool name 'list_templates' and description 'List available video templates that can be used as starting points' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
List available video templates that can be used as starting points. It is categorised as a Read tool in the Hyper Video Service MCP Server, which means it retrieves data without modifying state.
Register the Hyper Video Service 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 Hyper Video Service. 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 Hyper Video Service MCP server (twilson63/hyper-video-service). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
