Installation

Prerequisites

1. Node.js >= 20 (check with node --version)
2. Holded API Key - Get yours from Holded API Settings or go to Configuration (top bar) → API

Quick Start (npx)

The easiest way to use this MCP server is via npx - no installation or build required! Just configure your MCP client as shown below.

Setup for Claude Desktop

Add the following to your Claude Desktop configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "holded": {
      "command": "npx",
      "args": ["-y", "@energio/holded-mcp"],
      "env": {
        "HOLDED_API_KEY": "your_api_key_here"
      }
    }
  }
}

Restart Claude Desktop to load the server.

Setup for Claude Code

Add the server with a single command:

claude mcp add holded -- npx -y @energio/holded-mcp

Then set the API key in your environment:

export HOLDED_API_KEY=your_api_key_here

Setup for Cursor

Add the following to your Cursor MCP settings file:

• macOS: ~/.cursor/mcp.json
• Windows: %APPDATA%\Cursor\mcp.json
• Linux: ~/.config/cursor/mcp.json

{
  "mcpServers": {
    "holded": {
      "command": "npx",
      "args": ["-y", "@energio/holded-mcp"],
      "env": {
        "HOLDED_API_KEY": "your_api_key_here"
      }
    }
  }
}

After saving, restart Cursor or reload the MCP servers from the settings.

Setup for VS Code

Add the following to your VS Code user settings (settings.json) or workspace settings (.vscode/mcp.json):

User settings (settings.json):

{
  "mcp": {
    "servers": {
      "holded": {
        "command": "npx",
        "args": ["-y", "@energio/holded-mcp"],
        "env": {
          "HOLDED_API_KEY": "your_api_key_here"
        }
      }
    }
  }
}

Workspace settings (.vscode/mcp.json):

{
  "servers": {
    "holded": {
      "command": "npx",
      "args": ["-y", "@energio/holded-mcp"],
      "env": {
        "HOLDED_API_KEY": "your_api_key_here"
      }
    }
  }
}

Setup for Windsurf

Add the following to your Windsurf MCP configuration file:

• macOS: ~/.codeium/windsurf/mcp_config.json
• Windows: %APPDATA%\Codeium\windsurf\mcp_config.json
• Linux: ~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "holded": {
      "command": "npx",
      "args": ["-y", "@energio/holded-mcp"],
      "env": {
        "HOLDED_API_KEY": "your_api_key_here"
      }
    }
  }
}

Setup for Other MCP-Compatible Agents

Any MCP-compatible agent can use this server via npx. The general configuration requires:

1. Command: npx
2. Arguments: ["-y", "@energio/holded-mcp"]
3. Environment variable: HOLDED_API_KEY with your API key

Example configuration:

{
  "mcpServers": {
    "holded": {
      "command": "npx",
      "args": ["-y", "@energio/holded-mcp"],
      "env": {
        "HOLDED_API_KEY": "your_api_key_here"
      }
    }
  }
}

The server communicates via stdio using the MCP protocol and can be integrated with any client that supports the Model Context Protocol.

Configuration

The server requires a HOLDED_API_KEY environment variable. This is typically set in your MCP client configuration (see installation sections above).

For manual/development usage, you can set it directly:

export HOLDED_API_KEY=your_api_key_here

Module Selection

By default, all modules are enabled. To load only specific modules, set the HOLDED_MODULES environment variable with a comma-separated list:

Available modules: invoicing, crm, projects, accounting, team

Example - enable only invoicing module:

{
  "mcpServers": {
    "holded": {
      "command": "npx",
      "args": ["-y", "@energio/holded-mcp"],
      "env": {
        "HOLDED_API_KEY": "your_api_key_here",
        "HOLDED_MODULES": "invoicing"
      }
    }
  }
}

Configuration examples:

• All modules (default): Omit HOLDED_MODULES or leave it empty
• Only CRM: "HOLDED_MODULES": "crm"
• Only invoicing: "HOLDED_MODULES": "invoicing"
• Multiple modules: "HOLDED_MODULES": "invoicing,crm"

Debug Mode

Enable debug logging for API requests and retries by setting the HOLDED_DEBUG environment variable:

{
  "mcpServers": {
    "holded": {
      "command": "npx",
      "args": ["-y", "@energio/holded-mcp"],
      "env": {
        "HOLDED_API_KEY": "your_api_key_here",
        "HOLDED_DEBUG": "true"
      }
    }
  }
}

When enabled, the server will log retry attempts and API request failures to stderr, which can be helpful for troubleshooting connection issues or rate limiting.

Usage

Running the Server Manually

npm start

Or for development with auto-reload:

npm run dev

Note: In most cases, you won't run the server manually. Your MCP client (Cursor, Claude Desktop, etc.) will start and manage the server process automatically based on your configuration.
