MCP vtenext agent

mcp-vtenext

MCP server for VTENext CRM: exposes the WebService API as tools for Claude and other MCP-compatible clients.

Requirements

• Node.js 18+
• A running VTENext instance (self-hosted or Docker, see ../docker)

Setup

cd mcp/vtenext/server
npm install
cp .env.example .env

Edit .env:

VTENEXT_URL=http://your-vtenext-instance
VTENEXT_USERNAME=admin
VTENEXT_ACCESS_KEY=your_access_key
READ_ONLY=false

The access key is in VTENext under Admin → Users → [user] → Access Key.

Read-only mode

Set READ_ONLY=true to prevent any write operation on VTENext. When enabled, the tools create_opportunita, update_opportunita and add_nota_opportunita return an error instead of writing data.

This is useful when the server is used by AI bots or automated agents that should only read CRM data. To run a read-only instance alongside a full-access one, pass the variable via the MCP config:

{
  "mcpServers": {
    "vtenext-bot": {
      "type": "stdio",
      "command": "node",
      "args": ["/absolute/path/to/mcp/vtenext/server/index.js"],
      "env": {
        "VTENEXT_URL": "http://your-vtenext-instance",
        "VTENEXT_USERNAME": "admin",
        "VTENEXT_ACCESS_KEY": "your_access_key",
        "READ_ONLY": "true"
      }
    }
  }
}

Claude Code integration

Add to .mcp.json in your project root:

{
  "mcpServers": {
    "vtenext": {
      "type": "stdio",
      "command": "node",
      "args": ["/absolute/path/to/mcp/vtenext/server/index.js"]
    }
  }
}

Authentication

VTENext uses the vtiger WebService protocol:

1. GET /webservice.php?operation=getchallenge → token
2. MD5(token + accessKey) → hashed key
3. POST /webservice.php with operation=login (form-encoded) → sessionName

Sessions are cached for 4 minutes (token lifetime is 5 minutes).

Tests

# Unit tests (no VTENext required)
npm test

# Integration tests (requires live VTENext at VTENEXT_URL)
npm run test:integration
