Pruna MCP server

🎨 pruna-mcp-server

MCP server for Pruna AI — ultra-fast image generation, editing, upscaling, and video generation directly from your AI assistant.

Pruna AI is an inference API specialized in image and video generation. It offers sub-2-second image generation starting at $0.005/image, with models for text-to-image, image editing, upscaling, and video generation. This MCP server wraps their API so any MCP-compatible client (Claude Desktop, Kiro, Cursor) can generate visual content natively.

Conforms to MCP Specification 2025-11-25.

Features

• 8 MCP Tools: generateimage, editimage, tryonimage, upscaleimage, generatevideo, transformvideo, listmodels, upload_file
• 7 MCP Prompts: Product photos, virtual staging, social media visuals, game concept art, ad creatives, video ads, image enhancement
• 2 MCP Resources: pruna://models catalog for model discovery without tool calls

• Full MCP compliance: Tool annotations, structured content, progress notifications

Quick Start

# With uvx (zero install)
uvx pruna-mcp-server

# Or with pip
pip install pruna-mcp-server
pruna-mcp

Set your API key — get one at pruna.ai (go to the developer portal or contact Pruna to request access):

# macOS Keychain (recommended)
security add-generic-password -a $USER -s PRUNA_API_KEY -w "your-api-key"

# Linux (GNOME Keyring)
secret-tool store --label="Pruna API Key" service pruna-mcp-server key api_key <<< "your-api-key"

# Windows (PowerShell)
[System.Environment]::SetEnvironmentVariable("PRUNA_API_KEY", "your-api-key", "User")

# Or environment variable (all platforms)
export PRUNA_API_KEY="your-api-key"

MCP Client Configuration

Kiro CLI

Add to your agent config (e.g. ~/.kiro/agents/default.json):

In mcpServers:

"pruna": {
  "command": "sh",
  "args": ["-c", "PRUNA_API_KEY=$(security find-generic-password -a $USER -s PRUNA_API_KEY -w) uv run --directory /path/to/pruna-mcp-server pruna-mcp"],
  "autoApprove": ["generate_image", "edit_image", "try_on_image", "upscale_image", "generate_video", "transform_video", "list_models", "upload_file"]
}

In tools, add: "@pruna/*"

In allowedTools, add: "generateimage", "editimage", "tryonimage", "upscaleimage", "generatevideo", "transformvideo", "listmodels", "upload_file"

Note: Kiro agents use a tools whitelist with @server-name/* syntax and an allowedTools list. Both must include the Pruna tools for them to be available.

Claude Desktop

Add to ~/Library/Application Support/Claude/claudedesktopconfig.json (macOS):

{
  "mcpServers": {
    "pruna": {
      "command": "sh",
      "args": ["-c", "PRUNA_API_KEY=$(security find-generic-password -a $USER -s PRUNA_API_KEY -w) /path/to/uv run --directory /path/to/pruna-mcp-server pruna-mcp"]
    }
  }
}
