Details
From the project READMEWeb3Forms 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/mcpto 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.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
