# Installation

> Set up VIS42 MCP Server with your AI client

## Overview

The VIS42 MCP Server is **built into the platform**—there's no separate installation required. You simply need to configure your MCP-compatible AI client.

This guide covers setup for popular MCP clients.

## Prerequisites

Before you begin, ensure you have:

* An active VIS42 account
* An MCP-compatible AI client (such as Claude)

The recommended **Claude (Remote Connector)** flow signs you in with OAuth, so no API token is required. Only the **Claude Desktop Extension** flow needs a VIS42 API token.

## Choose Your Client

  <Tab title="Claude (Remote Connector)">
    Connect VIS42 straight from Claude — no download required. Authentication uses OAuth, so you never paste an API token.

    1. Open [Claude](https://claude.ai) and sign in.
    2. Go to **Settings → Connectors**.
    3. Click **Add custom connector**.
    4. Enter the VIS42 MCP Server URL:
       ```
       https://vis42.com/api/mcp
       ```
    5. Click **Add**, then **Connect**. Claude redirects you to VIS42 to sign in and authorize access.
    6. Approve the requested `mcp:use` scope. You'll be returned to Claude with VIS42 connected.

    VIS42 now appears in Claude's connector menu. Claude can work with your receivables, payables, expenses, ledger, and reconciliation — always scoped to your business role and permissions.

    2. Open Claude Desktop settings
    3. Navigate to **Extensions**
    4. Click **Advanced settings**
    5. Click **Install Extension**
    6. Select **vis42.mcpb**
    7. Click on **Install**
    8. Click [here](https://vis42.com/app/get-jwt-token) to get your VIS42 **API token**
    9. Insert the VIS42 **API token**
    10. Click on **Save**
    11. Enable **VIS42**

    If configured correctly, Claude will use the VIS42 MCP Server to retrieve your business information.
