WHAT IT DOES

What aes_gcm_decrypt does on Malware Analysis MCP Server

AI agents invoke aes_gcm_decrypt to trigger actions in Malware Analysis MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why aes_gcm_decrypt needs a policy

AES-GCM decryption executes a cryptographic operation that transforms ciphertext into plaintext. In the context of a malware analysis server, this could be used to decrypt malware payloads or obfuscated data. The empty description lowers confidence. It most likely falls under Execute (running a cryptographic transformation) rather than Read, as it actively processes and transforms data.

From the tool's definition Tool name 'aes_gcm_decrypt' on a malware analysis server with sibling tool 'aes_gcm_encrypt'. Description is empty and uninformative.

Verdict

aes_gcm_decrypt Rate-limited

aes_gcm_decrypt stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Malware Analysis MCP Server. Nothing to install.

What risk level is aes_gcm_decrypt? +

aes_gcm_decrypt is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit aes_gcm_decrypt? +

Yes. Add a rate_limit block to the aes_gcm_decrypt 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.

How do I block aes_gcm_decrypt completely? +

Set action: deny in the PolicyLayer policy for aes_gcm_decrypt. 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.

What MCP server provides aes_gcm_decrypt? +

aes_gcm_decrypt is provided by the Malware Analysis MCP Server MCP server (securitytalent/malware-analysis-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
