ABRA Flexi Server

Local stdio MCP server for ABRA Flexi / FlexiBee accounting workflows. It is intended for agent clients such as Codex, Claude Desktop, or any MCP-compatible local runtime that can launch a Node process.

This is the standalone MCP project. The separate remote ChatGPT App project is here: vvitovec/abra-flexi-chatgpt-app.

What It Does

• connects to ABRA Flexi over the official REST API
• reads companies, evidence metadata, records, partners, products, balances, overdue items, and accounting summaries
• prepares accountant-focused document drafts
• supports guarded write flows with validation, dry-run style checks, confirmations, and an audit log
• keeps Flexi credentials out of prompts and MCP tool arguments

Safety Model

The server is configured through flexi.config.json profiles. Each profile controls:

• Flexi base URL and company slug
• test or production mode
• default response format
• which env vars contain credentials
• read, dry-run, and write evidence allowlists
• whether writes require confirmation

Writes are not free-form passthrough calls. Tool handlers build known payloads, validate them, enforce evidence permissions, and record request audit files under .flexi-harness/logs.

Setup

npm install
cp .env.example .env

Edit .env with a dedicated ABRA Flexi REST API user:

FLEXI_PROD_USERNAME=api-user
FLEXI_PROD_PASSWORD=replace-me

Then edit flexi.config.json:

{
  "defaultProfile": "prod",
  "profiles": {
    "prod": {
      "baseUrl": "https://example.flexibee.eu",
      "company": "example_company_s_r_o_",
      "usernameEnv": "FLEXI_PROD_USERNAME",
      "passwordEnv": "FLEXI_PROD_PASSWORD"
    }
  }
}

Run Locally

npm run dev

For a production-style build:

npm run build
npm start

Codex MCP Config

After building, add a server entry like this to your Codex config:

[mcp_servers.abra_flexi]
command = "node"
args = ["/absolute/path/to/abra-flexi-mcp-server/dist/index.js"]
enabled = true

The server loads .env and flexi.config.json from the project directory.

Main Tool Areas

• company and evidence discovery
• flexible read-only evidence queries
• partner and product search
• invoice, payable, receivable, bank, cash, and internal document workflows
• overdue and saldo summaries
• accountant-first draft creation and guarded posting
• latest-error explanation from the local audit log

Verification

npm run check
npm test
npm run build

The tests use mocked HTTP servers and fixture-style responses. They do not need real ABRA Flexi credentials.
