Get sample metafield configuration for sandbox analysis.
AI agents call get_sample_metafield to retrieve information from Threat Zone MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves configuration metadata for sandbox analysis. It is a read-only operation that queries or fetches information without modifying, creating, deleting, or executing any actions. The blast radius of misuse is minimal—an agent could only access sample configuration data, which poses no meaningful security risk.
From the tool's definition Tool name 'get_sample_metafield' and description 'Get sample metafield configuration for sandbox analysis' indicate a retrieval operation. The verb 'Get' and context of retrieving configuration metadata demonstrate no data modification or side effects.

PolicyLayer is an MCP gateway — it sits between your AI agents and Threat Zone MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_sample_metafield:
{
"version": "1",
"default": "deny",
"tools": {
"get_sample_metafield": {}
}
}get_sample_metafield is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get sample metafield configuration for sandbox analysis. It is categorised as a Read tool in the Threat Zone MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Threat Zone MCP Server MCP server in PolicyLayer and add a rule for get_sample_metafield: 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 Threat Zone MCP Server. Nothing to install.

Yes. Add a rate_limit block to the get_sample_metafield 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 get_sample_metafield. 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.
get_sample_metafield is provided by the Threat Zone MCP Server MCP server (threat-zone/threatzonemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Threat Zone MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
