Fiken MCP by usefulapi

Use your Fiken account from Claude, Cursor, or any MCP client. Read companies, contacts, invoices, purchases, sales, ledger and bank balances, and create contacts, products and invoice drafts. Hosted, no local install: connect with your own credentials.

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

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://fiken.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http fiken https://fiken.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": {
    "fiken": {
      "url": "https://fiken.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 you sign in with your Fiken account.

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

On first connect you sign in to Fiken and approve access for the companies you choose. The company needs Fiken's API module, ordered in Fiken under Innstillinger. The server stores the access per user. No keys go in config files.
