Overview

AI-generated overview

Hosted MCP server for Fiken accounting: read invoices, bills, contacts, ledger and bank balances, and create contacts, products and invoice drafts.

What you can do
  • Look up the signed-in user, companies, chart of accounts, account and bank balances
  • Browse contacts, products, projects and time entries
  • Read issued invoices, drafts, credit notes, offers, order confirmations, sales and purchases
  • Inspect journal entries, ledger transactions and inbox documents
  • Create contacts, products and invoice drafts
  • Issue a draft as a real invoice and send it to the customer
When to use it
Useful when you want an assistant to answer questions about a Norwegian company's Fiken books, such as overdue invoices, unpaid supplier bills or today's bank balances, or to prepare invoice drafts and new contacts without leaving the chat.
Requirements
A remote MCP endpoint added by URL only; sign-in happens through OAuth with your own Fiken account, so no API key or Authorization header goes in the client config. The company must have Fiken's API module activated. A free plan allows 50 tool calls per month; paid plans are available.
Before you install
Write tools change Fiken data: issuing an invoice from a draft is irreversible and books it in the ledger, and sending an invoice by email, EHF, eFaktura, SMS or letter cannot be recalled (letters cost extra). Confirm before any write. Paid plans are billed through a payment link, and the free tier is capped at 50 calls per month. Access is granted per company in Fiken.

Installation

In SourceWeft

  1. Open Fiken MCP by usefulapi in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.usefulapi%2Ffiken/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

README

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:
json
{  "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.
