Overview

What is ZIP MCP Server?

ZIP MCP Server is a compression server built on fastMCP and zip.js that implements the Model Context Protocol (MCP). It provides fully parameter-controlled ZIP compression, decompression, and query of compressed package information for AI clients.

How to use ZIP MCP Server?

Install globally via npm (npm install -g zip-mcp), then add the server to your MCP JSON configuration with the command zip-mcp. After configuration, AI clients (e.g., Claude, Raycast, Cursor) can call its tools (compress, decompress, getZipInfo, echo) through the MCP protocol.

Key features of ZIP MCP Server

Compression and decompression of files and data
Multi-file packaging compression
Compression level control (0–9)
Password protection and encryption strength settings (1–3)
Query function for compressed package metadata
Validates ZIP entry paths to prevent path traversal writes

Use cases of ZIP MCP Server

Compress local files or directories into a password-protected ZIP archive
Decompress ZIP files to a specified directory with overwrite control
Inspect metadata (file count, sizes, compression ratio) of a ZIP file
Test MCP connectivity via the echo tool

Frequently asked questions

What runtime does ZIP MCP Server require?

It is installed via npm, so Node.js is required. The README does not specify a minimum version.

Can I password-protect a ZIP archive?

Yes. The `compress` tool accepts an optional `password` parameter and an `encryptionStrength` parameter (1–3).

Where does the server read and write files?

All operations are on local files as specified by the `input` and `output` parameters. No remote storage is involved.

How does the server prevent arbitrary file writes during decompression?

Starting from version 1.0.6, extraction validates each ZIP entry path against the output root, rejecting absolute paths, drive-letter paths, `..` segments, and any path that would escape the output directory.

What transport does the MCP server use?

The server is configured via a JSON entry with a command (`zip-mcp`) and no explicit transport arguments, implying it uses standard input/output (stdio) transport as typical for MCP servers.
