Pack: web-fetch · Connect: https://pipeworx.io/mcp (see Connect below for a single-pack URL)

No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/extract_archive_member for the schema, then POST the same URL with its arguments for the data.

List or extract a named member from a ZIP archive at a public URL, without downloading the whole archive when the origin honours HTTP Range (most do, including Internet Archive Wayback Machine captures).

Parameters

Name	Type	Required	Description
`url`	string	yes	The absolute http(s) URL of a ZIP archive, e.g. an Internet Archive Wayback Machine capture of a .zip, an object-store URL, or any direct ZIP download link.
`member`	string	no	The exact (or case-insensitive) name of the archive member to extract, as returned by a prior call without “member”. Omit to list members instead.
`format`	string	no	Only used when extracting a member. auto (default) and raw both return decoded text for a textual member and base64 for binary; text forces a text decode (falls back to base64 with a warning if the member looks binary).
`max_bytes`	number	no	Only used when extracting a member: size of the returned window. Default 100000. Maximum 1000000 for text, 512000 for base64 (binary).
`offset`	number	no	Only used when extracting a member: byte offset into the DECOMPRESSED member where the window starts. Use next_offset from the previous call to page. Default 0.
