Overview

AI-generated overview

Hosted MCP server that lets an assistant read KashFlow accounting data — invoices, customers, suppliers, banking and reports — and add customers, suppliers…

What you can do
  • Read company details, customers, suppliers and the product catalogue, including balances and lookups by code, ID or email.
  • Browse sales invoices, quotes, purchases and payments by date range, customer, supplier, unpaid or overdue status, plus invoice notes.
  • Inspect bank accounts, transactions and balances, nominal codes, VAT rates and projects.
  • Pull financial reports: profit and loss, balance sheet, trial balance, aged debtors and creditors, VAT return figures and KPIs.
  • Create customers and suppliers, add invoice notes, and check usage or manage the subscription.
When to use it
Useful when you want to ask questions about a KashFlow account in plain language — outstanding debt, overdue invoices, profit and loss for a period, VAT figures — or add a customer or invoice note without opening KashFlow.
Requirements
Remote endpoint reached over streamable HTTP; no local install. Sign-in uses OAuth, and the login page asks for your KashFlow username and password (or the separate API password, with API access enabled under Apps > API Settings). No API key or Authorization header goes in the client config.
Before you install
The login page collects your KashFlow credentials, which the service stores per user. Create-customer, create-supplier and add-invoice-note tools write to your accounting data, so confirm before running them. The free tier allows 50 calls a month; paid plans cost $9/month or $90/year (Pro) and $39/month or $390/year (Pro+), billed through a Stripe checkout link, with no refund for the current period on cancellation.

Installation

In SourceWeft

  1. Open KashFlow 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%2Fkashflow/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

KashFlow MCP by usefulapi

Use KashFlow from Claude, Cursor, or any MCP client — work with your invoices, customers, suppliers, banking and accounting reports. Hosted, no local install: connect with your own KashFlow credentials.

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

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://kashflow.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http kashflow https://kashflow.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": {    "kashflow": {      "url": "https://kashflow.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 KashFlow credentials.

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

On first connect you'll enter your KashFlow username and password (or the separate API password; enable API access under Apps > API Settings). They are validated, stored per-user, and scoped to you — no keys in config files.
