Overview

Description from the maker (original English)

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

Common questions

Is Web3Forms MCP by usefulapi safe?

It passed 3 of 3 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 (1.2.4) reached the registry today.

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.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, AvaHR

Web3Forms MCP by usefulapi

Use your Web3Forms account from Claude, Cursor, or any MCP client. List forms and read their submissions, and create submissions. Hosted, no local install: connect with your own credentials.

Live endpoint: https://web3forms.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://web3forms.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http web3forms https://web3forms.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
{

"mcpServers": { "web3forms": { "url": "https://web3forms.usefulapi.io/mcp" } } }

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Web3Forms credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/web3forms/

On first connect you provide a Web3Forms Submissions API key (Web3Forms → Dashboard → Account → API Keys). Tick Create submissions only if you want the assistant to create them. The server validates it and stores it per user. No keys go in config files.
