Render a curated AGT YAML policy template into disabled/shadow YAML. Template params must not include secrets.
AI agents call render_policy_template to retrieve information from Tuning Engines - LLM Fine-Tuning without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though render_policy_template only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
Render a curated AGT YAML policy template into disabled/shadow YAML. Template params must not include secrets. It is categorised as a Read tool in the Tuning Engines - LLM Fine-Tuning MCP Server, which means it retrieves data without modifying state.
Register the Tuning Engines - LLM Fine-Tuning MCP server in PolicyLayer and add a rule for render_policy_template: 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 Tuning Engines - LLM Fine-Tuning. Nothing to install.
render_policy_template 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 render_policy_template 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 render_policy_template. 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.
render_policy_template is provided by the Tuning Engines - LLM Fine-Tuning MCP server (tuningengines-cli). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
