Unzip a .zip file into project assets directory
AI agents use assets_unzip to create or update resources in 8th Wall MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your 8th Wall MCP Server environment.
Unzipping files into a project directory creates or modifies project state by populating it with new files or overwriting existing ones. This is reversible (files can be deleted or re-extracted differently), so it falls under Write rather than Destructive.
From the tool's definition Tool name is 'assets_unzip' and description states it will 'Unzip a .zip file into project assets directory', which modifies the project by extracting and adding files to the assets directory.
Documented attack patterns abuse exactly the kind of access assets_unzip 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_unzip:
{
"version": "1",
"default": "deny",
"tools": {
"assets_unzip": {
"limits": [
{
"counter": "assets_unzip_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}assets_unzip stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Unzip a .zip file into project assets directory. It is categorised as a Write tool in the 8th Wall MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the 8th Wall MCP Server MCP server in PolicyLayer and add a rule for assets_unzip: 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_unzip is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the assets_unzip 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_unzip. 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_unzip 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.
