AI agents call extract_assets to retrieve information from Ffdecmcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to extract or export assets (images, audio, fonts, etc.) from compiled SWF files as part of decompilation workflow. This is a read operation that retrieves data from the file without modifying the original or executing arbitrary code.
From the tool's definition Tool name 'extract_assets' in a decompilation/analysis context suggests retrieving embedded resources from SWF files without modification. No destructive or execution capability implied.
Attacks that exploit this kind of access
extract_assets. It is categorised as a Read tool in the Ffdecmcp MCP Server, which means it retrieves data without modifying state.
Register the Ffdec MCP server in PolicyLayer and add a rule for extract_assets: 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 Ffdecmcp. Nothing to install.
extract_assets 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 extract_assets 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 extract_assets. 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.
extract_assets is provided by the Ffdec MCP server (sublimnl/ffdecmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
