WHAT IT DOES

What compress does on ZIP-MCP

AI agents use compress to create or update resources in ZIP-MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ZIP-MCP environment.

RISK

Why compress is rated Medium

This tool creates a new ZIP archive from local files or directories. It is a Write operation as it creates a new file on disk. It does not delete the originals (no destructive behavior described), but misuse could overwrite existing ZIP files, hence medium severity.

RECOMMENDED RULE

The rule that runs compress safely

PolicyLayer is an MCP gateway: it sits between your AI agents and ZIP-MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For compress, this is the rule to start with:

compress Rate-limited

compress 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.

The button opens the PolicyLayer dashboard: create your workspace, connect ZIP-MCP, apply this rule, and every compress call is checked against it from then on.

How do I enforce a policy on compress? +

Register the ZIP MCP server in PolicyLayer and add a rule for compress: 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 ZIP-MCP. Nothing to install.

What risk level is compress? +

compress is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit compress? +

Yes. Add a rate_limit block to the compress 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 compress completely? +

Set action: deny in the PolicyLayer policy for compress. 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 compress? +
