Save a static resource from a network request to a local file. File extension is automatically determined.
AI agents use save_static_resource to create or update resources in ReverseCraft DevTools MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ReverseCraft DevTools MCP environment.
This tool performs a write operation—it captures a network resource and persists it to local storage. While reversible (files can be deleted), it modifies the local file system state. The severity is medium because uncontrolled use could fill disk space, overwrite sensitive files, or exfiltrate data from network responses, but the operation itself is not destructive or irreversible in the traditional sense.
From the tool's definition Tool description states it 'Save[s] a static resource from a network request to a local file', which creates or writes data to the file system.
Documented attack patterns abuse exactly the kind of access save_static_resource gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ReverseCraft DevTools MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for save_static_resource:
{
"version": "1",
"default": "deny",
"tools": {
"save_static_resource": {
"limits": [
{
"counter": "save_static_resource_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}save_static_resource 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.

Save a static resource from a network request to a local file. File extension is automatically determined. It is categorised as a Write tool in the ReverseCraft DevTools MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the ReverseCraft DevTools MCP server in PolicyLayer and add a rule for save_static_resource: 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 ReverseCraft DevTools MCP. Nothing to install.
save_static_resource 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 save_static_resource 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 save_static_resource. 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.
save_static_resource is provided by the ReverseCraft DevTools MCP server (reverse-craft/rc-devtools-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from ReverseCraft DevTools MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
