Overview

AI-generated overview

Remote MCP server for ABRA Flexi accounting: read invoices, contacts, stock and payments, and create contacts or draft invoices.

What you can do
  • Check the connected company and list its evidences (tables)
  • List and read issued and received invoices, including line items and amounts still to pay
  • Search the address book, price list, stock cards, stock movements, orders, bank and cash movements
  • List or fetch records of any business evidence with ABRA Flexi filter expressions
  • Create or update address-book entries and create issued invoices, with a dry-run option
  • Report usage, request a feature, upgrade or cancel the paid plan
When to use it
Useful when the user works with ABRA Flexi and wants an assistant to answer questions about overdue invoices, open payments, stock levels or customer data, or to prepare new contacts and invoices without switching to the ABRA Flexi interface.
Requirements
A remote endpoint reached by URL; no package or local runtime. An API-enabled ABRA Flexi account, signed in through OAuth on the server's login page with the user's ABRA Flexi credentials. No API key or Authorization header is added to the client config. A paid plan is needed beyond the free monthly call allowance.
Before you install
Three tools write to ABRA Flexi: creating and updating contacts and creating issued invoices; a created invoice gets the next number in its series and may be accounted automatically, so confirm before running and use dry_run first. The login page asks for ABRA Flexi credentials, which are handled by the hosted service. Usage is metered: the free plan allows 50 calls a month, and paid plans are billed through a Stripe checkout link returned by the upgrade tool.

Installation

In SourceWeft

  1. Open ABRA Flexi 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%2Fabra-flexi/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

Connect

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

abraflexi_create_issued_invoice

Create an issued invoice

WRITE: create an issued invoice (faktura-vydana) with line items in ABRA Flexi.

Use dry_run first to see the computed totals and validation errors without saving. Find document_type_code with abraflexi_list_records (evidence typ-faktury-vydane) and customer_code with abraflexi_list_contacts.
