- Homepage: https://github.com/7gugu/zip-mcp
- Risk category: Write (Medium risk)
- Registry record: grade A, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "decompress",
    "arguments": {}
  }
}
```

## Why decompress is rated Medium

Decompressing a ZIP file writes new files and directories to the filesystem. This is reversible (the extracted files can be deleted), so it falls under Write rather than Destructive. However, it could overwrite existing files at the destination path, which raises the severity to medium. It does not execute code or move money.

From the tool's own definition: "'Decompress local ZIP file to specified directory' — creates new files in a target directory"

## Use case

AI agents use decompress 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.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches ZIP-MCP:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "decompress": {
      "limits": [
        {
          "counter": "decompress_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
```

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
