Ebook File Check tools (2, 1 write)

  • ebook_checkFree

    Validates one EPUB (a directly hosted public URL or a file attached in chat) against the EPUB 2/3 specification using a pinned local EPUBCheck 5.4.0 engine run in a no-network sandbox. Each call takes exactly one source: the url parameter or the file attachment, never both. Returns the automated verdict: pass boolean, EPUB version, message counts by severity (fatal/error/warning/usage), findings grouped most-severe-first with EPUBCheck rule id (RSC-005, OPF-014, …), file path and line/column, plus a structural inventory (spine items, media types, remote-resource state), SHA-256 of the exact bytes, and truncation metadata. Use for one-file readiness and diagnosis: 'is this ebook valid', 'does this EPUB have specification problems before upload', 'what is wrong with it'. A pass means only that the bytes satisfied the automated profile; it never renders the book, judges accessibility, or guarantees any store will accept it, and human review of how the book reads and looks is always required. Downloads and validates a live EPUB under a 110-second call deadline; tell the user before the call.

  • ebook_comparewrite actionFree

    Runs the identical pinned EPUBCheck 5.4.0 validation over exactly two EPUB builds (directly hosted public URLs or files attached in chat, baseline first, revised second) sequentially under one shared 110-second deadline, then reports which spec findings regressed or were fixed between them. Returns per-build hashes, EPUB versions, pass verdicts and severity counts, a regressions list (rules that appear or worsen in the revised build) and a fixed list (rules removed or reduced), and a ranking by pass state then fewer blocking findings. Use for 'did my re-export get worse', 'which build has fewer problems', and revision-over-revision questions. The ranking orders automated conformance only (it never means one build renders, reads, or sells better), and when both builds tie on pass state and blocking count it names no winner rather than crowning the first submission. It also flags when the two files declare different titles, since that usually means they are not two builds of one book. Human review remains required for both builds. A comparison can take up to 110 seconds under its shared deadline; tell the user before the call.

PowMCP MCP server guide

PowMCP provides hosted, task-specific MCP servers. This repository documents three of them, their remote connection URLs, and their public MCP Registry descriptors. The hosted server implementation is proprietary and is not contained in this repository. You do not need to install or run code from this repository to use the servers.

Each URL is a separate remote MCP server using Streamable HTTP. Add only the URL for the tool you need to an MCP client that supports remote servers. For example, a client that accepts an mcpServers JSON entry can use:

{
  "mcpServers": {
    "powmcp-ssl-certificate-check": {
      "type": "http",
      "url": "https://powmcp.com/ssl-certificate-check/mcp"
    }
  }
}

Replace the name and URL with one of the other entries above to connect another server. The individual app pages also provide client-specific connection buttons and commands. If your client requests authorization, complete its native sign-in flow. Client support for PowMCP account linking varies; consult the connection instructions on the app page. Usage allowances and any paid options are shown on the PowMCP apps and usage page.

The guides explain each tool's input and what its result can establish. For help with connection or results, contact support@powmcp.com. See support and security for reporting guidance.

The MIT license applies to documentation, descriptors, and example configuration in this repository. It does not grant a license to the proprietary hosted implementation or to PowMCP's names and logos. References to third-party validation standards and components in the guides do not imply ownership of them by PowMCP.
