Compresses Nova Act log files to reduce size while preserving important information. Optionally extracts embedded screenshots to a separate directory before compression. Use this tool to prepare logs for storage or transmission when they become too large for efficient handling.
AI agents invoke compress_logs to trigger actions in Nova Act. 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.
This tool performs file system operations: compressing log files and optionally extracting screenshots to a separate directory. It modifies files on disk (compression, extraction) which constitutes an execution of a file transformation operation.

Documented attack patterns abuse exactly the kind of access compress_logs gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Nova Act, and nothing reaches the server without passing your rules. This is the rule we recommend for compress_logs:
{
"version": "1",
"default": "deny",
"tools": {
"compress_logs": {
"limits": [
{
"counter": "compress_logs_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}compress_logs 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.

Compresses Nova Act log files to reduce size while preserving important information. Optionally extracts embedded screenshots to a separate directory before compression. Use this tool to prepare logs for storage or transmission when they become too large for efficient handling. It is categorised as a Execute tool in the Nova Act MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Nova Act MCP server in PolicyLayer and add a rule for compress_logs: 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 Nova Act. Nothing to install.
compress_logs is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the compress_logs 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 compress_logs. 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.
compress_logs is provided by the Nova Act MCP server (madtank/nova-act-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Nova Act, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
