  • 🎯 Comprehensive Parameters - Supports all ConvertAPI parameters including PageSize, PageOrientation, Quality, StoreFile, etc.
  • 🤖 AI-Ready - Seamlessly integrates with Claude Desktop, Cline, and other MCP-compatible AI assistants
  • 📦 Local - Supports local file operations

Installation

Prerequisites

  • .NET 9.0 SDK or later
  • A ConvertAPI account and API Token (Get one free)

Configuration

  1. Clone the repository:

git clone https://github.com/ConvertAPI/convertapi-mcp cd ConvertAPI-MCP

  1. Set your ConvertAPI API Token as an environment variable:

Windows (PowerShell): $env:CONVERTAPI_TOKEN = "your_api_token_here" $env:CONVERTAPI_BASE_URI = "https://v2.convertapi.com"

Linux/macOS: export CONVERTAPI_TOKEN="your_api_token_here" export CONVERTAPI_BASE_URI="https://v2.convertapi.com"

  1. Build the project: dotnet build

Usage

Configuration:

Set the following in your application configuration:

Local Mode (with file download): dotnet run --project "CA.MCP.Local"

Integration with AI Assistants

Claude Desktop Configuration

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "convertapi": {
      "command": "dotnet",
      "args": [
        "run",
        "--project",
        "C:\\Path\\To\\CA.MCP.Local\\CA.MCP.Local.csproj",
        "--no-build"
      ],
      "env": {
        "CONVERTAPI_TOKEN": "your_api_token_here",
        "CONVERTAPI_BASE_URI": "https://v2.convertapi.com"
      }
    }
  }
}

Cline (VSCode Extension)

Add to your MCP settings in Cline:

{
  "convertapi": {
    "command": "dotnet",
    "args": [
      "run",
      "--project",
      "/path/to/CA.MCP.Local",
      "--no-build"
    ],
    "env": {
      "CONVERTAPI_TOKEN": "your_api_token_here",
      "CONVERTAPI_BASE_URI": "https://v2.convertapi.com"
    }
  }
}

Prefer a Hosted MCP? (No Setup Required)

If you do not want to install .NET or run your own server, you can use the hosted ConvertAPI MCP instead.

Hosted endpoint:

https://mcp.convertapi.io

Just configure your MCP client to use the hosted endpoint and provide your ConvertAPI API Token.

Example (Claude Desktop)

{
  "mcpServers": {
    "convertapi": {
      "url": "https://mcp.convertapi.io",
      "env": {
        "CONVERTAPI_TOKEN": "your_api_token_here"
      }
    }
  }
}

That’s it. Your AI agent can immediately start converting documents across 200+ formats using structured MCP tool calls.

If you need full control, private networking, or custom deployment, continue with the self-hosted setup.
