AI agents call app_list 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 performs a read-only query to enumerate 8th Wall applications. It has no side effects, does not modify data, execute code, delete resources, or commit financial transactions. The mock implementation reinforces that this is a simple data retrieval operation. Blast radius is minimal as listing apps cannot harm systems or data.
From the tool's definition Tool name 'app_list' and description 'List 8th Wall apps' indicate a retrieval operation that queries existing applications without modifying, deleting, or executing external operations.
Documented attack patterns abuse exactly the kind of access app_list 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 app_list:
{
"version": "1",
"default": "deny",
"tools": {
"app_list": {}
}
}app_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
List 8th Wall apps (mock unless API configured). 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 app_list: 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.
app_list 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 app_list 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 app_list. 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.
app_list 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.
