Common questions
Is SSL Certificate Check safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.2.5) reached the registry 2 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

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.
| Server | Remote MCP endpoint | Tools | Guide | Registry descriptor |
|---|---|---|---|---|
| SSL Certificate Check | https://powmcp.com/ssl-certificate-check/mcp | ssl_check | SSL guide | server.json |
| Ebook File Check | https://powmcp.com/epub-check/mcp | ebook_check, ebook_compare | EPUB guide | server.json |
| Caption File Check | https://powmcp.com/caption-file-check/mcp | caption_check, caption_compare | Caption guide | server.json |
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.
