Tools
Details
From the project READMEWeFact MCP by usefulapi
Use your WeFact account from Claude, Cursor, or any MCP client. It reads customers, invoices, products and subscriptions, and it changes nothing. Hosted, no local install: connect with your own credentials.
Live endpoint: https://wefact.usefulapi.io/mcp · Homepage: https://usefulapi.io
Connect
- Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste
https://wefact.usefulapi.io/mcp. - Claude Code:
claude mcp add --transport http wefact https://wefact.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": {
"wefact": {
"url": "https://wefact.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 WeFact credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/wefact/
On first connect you provide your WeFact API key (Settings → API; the API must be switched on there). 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.
