AI agents call assets_status to retrieve information from 8th Wall 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 the status/availability state of an external asset integration (PolyHaven). It queries information without creating, modifying, deleting, executing code, or causing financial impacts. This is a straightforward read operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool named 'assets_status' with description 'Report availability of PolyHaven integration' — the word 'report' and 'availability' indicate status checking or querying without modification.
Documented attack patterns abuse exactly the kind of access assets_status gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and 8th Wall MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for assets_status:
{
"version": "1",
"default": "deny",
"tools": {
"assets_status": {}
}
}assets_status is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Report availability of PolyHaven integration. It is categorised as a Read tool in the 8th Wall MCP Server MCP Server, which means it retrieves data without modifying state.
Register the 8th Wall MCP Server MCP server in PolicyLayer and add a rule for assets_status: 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 8th Wall MCP Server. Nothing to install.
assets_status 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 assets_status 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 assets_status. 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.
assets_status is provided by the 8th Wall MCP Server MCP server (superdwayne/8thwallmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from 8th Wall MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
