zapcap-mcp-server 0.1.8

MCP server for ZapCap.ai video processing and caption generation

ZapCap MCP Server

NOTE: This is an unofficial implementation of MCP Server for ZapCap.

An MCP (Model Context Protocol) server that provides tools for uploading videos, creating processing tasks, and monitoring their progress through the ZapCap API.

Requirements

• uv
• ZapCap API key

You can install uv from here: https://docs.astral.sh/uv/

You can get api key from ZapCap API after registation at https://zapcap.ai/ in their platform here: https://platform.zapcap.ai/dashboard/api-key

Installation in MCP-client

Add to your MCP client mcp.json configuration (e.g., Claude Desktop, Cursor and etc.):

{
  "mcpServers": {
    "zapcap": {
      "command": "uvx",
      "args": ["zapcap-mcp-server"],
      "env": {
        "ZAPCAP_API_KEY": "your_api_key_here"
      }
    }
  }
}

Alternative Installation

uv tool install zapcap-mcp-server

Docker Installation

You can also run the MCP server in a Docker container using the pre-built image from Docker Hub:

Using pre-built image from Docker Hub:

{
  "mcpServers": {
    "zapcap": {
      "command": "docker",
      "args": [
        "run", 
        "--rm", 
        "--init",
        "-i",
        "--net=host",
        "-v", "/home/$USER:/host/home/$USER",
        "-e", "ZAPCAP_API_KEY=your_api_key_here",
        "bogdan01m/zapcap-mcp-server:latest"
      ],
      "env": {
        "DOCKER_CLI_HINTS": "false"
      }
    }
  }
}

Configuration

Set your ZapCap API key as an environment variable:

export ZAPCAP_API_KEY="your_api_key_here"

Benefits Over Direct API Usage

Token Management

Unlike using curl or direct API calls where you need to manually include your API key in every request:

# Traditional curl approach - token needed every time
curl -X POST "https://api.zapcap.ai/upload" \
  -H "Authorization: Bearer your_token_here" \
  -F "file=@video.mp4"

With this MCP server, your API key is configured once in the environment and automatically used for all operations:

{
  "env": {
    "ZAPCAP_API_KEY": "your_api_key_here"
  }
}

Natural Language Interface

Instead of constructing complex API requests with parameters, you can describe what you want:

Traditional API:

curl -X POST "https://api.zapcap.ai/tasks" \
  -H "Authorization: Bearer token" \
  -d '{
    "video_id": "abc123",
    "template_id": "viral",
    "font_size": 30,
    "highlight_color_1": "#00ff00",
    "enable_broll": true,
    "broll_percent": 40
  }'

MCP Server:

"Add green highlighted subtitles with 40% B-roll using viral template"

Type Safety & Validation

• Pydantic Integration: All parameters are validated automatically with type checking

Future Plans

Testing Integration

We're planning to add basic testing capabilities:

• API Integration Tests: Verify that ZapCap API calls work correctly
• MCP Tool Tests: Ensure all MCP tools respond properly to requests

Planned Features

• Named configurations: Save frequently used parameter combinations ("my_brand", "youtube_style")
• Template enhancement: Override template defaults with consistent brand colors/fonts
