Magic pack

Magic pack is a tool that makes it easy to compress and decompress files without remembering lots of commands.

Quick install

cargo install magic-pack

MCP server

Install the optional MCP server binary:

cargo install magic-pack --features mcp --bin magic-pack-mcp

Example MCP client config:

{
  "mcpServers": {
    "magic-pack": {
      "command": "magic-pack-mcp",
      "env": {
        "MAGIC_PACK_MCP_ALLOWED_ROOT": "/absolute/path/you/want/to/allow"
      }
    }
  }
}

Codex config example (~/.codex/config.toml):

[mcp_servers.magic-pack]
command = "magic-pack-mcp"

[mcp_servers.magic-pack.env]
MAGIC_PACK_MCP_ALLOWED_ROOT = "/absolute/path/you/want/to/allow"

Local test example:

{
  "mcpServers": {
    "magic-pack": {
      "command": "magic-pack-mcp",
      "env": {
        "MAGIC_PACK_MCP_ALLOWED_ROOT": "/Users/zonda/Repos/magic-pack"
      }
    }
  }
}

Codex config example (~/.codex/config.toml):

[mcp_servers.magic-pack]
command = "cargo"
args = ["run", "--features", "mcp", "--bin", "magic-pack-mcp"]
cwd = "/Users/zonda/Repos/magic-pack"

[mcp_servers.magic-pack.env]
MAGIC_PACK_MCP_ALLOWED_ROOT = "/Users/zonda/Repos/magic-pack"

After saving the MCP config, restart your MCP client so it re-runs magic-pack-mcp. Then call the tools with absolute paths inside MAGIC_PACK_MCP_ALLOWED_ROOT, for example:

compress /Users/zonda/Repos/magic-pack/temp/test_dir to /Users/zonda/Repos/magic-pack/temp/test_dir.zip as zip
decompress /Users/zonda/Repos/magic-pack/temp/test_dir.zip to /Users/zonda/Repos/magic-pack/temp/test_dir_unpacked
detect file type of /Users/zonda/Repos/magic-pack/temp/test_dir.zip
list supported formats
