Return the org IaC standards: naming pattern, allowed regions, required
AI agents call list_standards to retrieve information from Claude Iac 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 organizational infrastructure-as-code standards (naming patterns, allowed regions, required tags). It performs a read-only operation that retrieves configuration metadata without modifying, creating, executing, or deleting any resources.
From the tool's definition Tool name 'list_standards' and description 'Return the org IaC standards' indicate data retrieval with no side effects.
Attacks that exploit this kind of access
Return the org IaC standards: naming pattern, allowed regions, required. It is categorised as a Read tool in the Claude Iac MCP Server, which means it retrieves data without modifying state.
Register the Claude Iac MCP server in PolicyLayer and add a rule for list_standards: 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 Claude Iac. Nothing to install.
list_standards 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_standards 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_standards. 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_standards is provided by the Claude Iac MCP server (net9876/claude-iac-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
