Option 2: Build from Source

1. Clone the repository:

   git clone https://github.com/okooo5km/unsplash-mcp-server-go.git
   cd unsplash-mcp-server-go
   

2. Build the project:

   Using Make (recommended):

   # Build for your current platform
   make
   
   # Or build for a specific platform
   make build-darwin-universal    # macOS Universal Binary
   make build-darwin-arm64        # macOS Apple Silicon
   make build-darwin-amd64        # macOS Intel
   make build-linux-amd64         # Linux x86_64
   make build-linux-arm64         # Linux ARM64
   make build-windows-amd64       # Windows x86_64
   
   # Or build for all platforms at once
   make build-all
   
   # Create distribution packages for all platforms
   make dist
   

   The binaries will be placed in the .build directory.

   Using Go directly:

   go build -o unsplash-mcp-server
   

3. Install the binary:

   # Install to user directory (recommended, no sudo required)
   mkdir -p ~/.local/bin
   cp unsplash-mcp-server ~/.local/bin/
   

   Make sure ~/.local/bin is in your PATH by adding to your shell configuration file:

   echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.zshrc  # or ~/.bashrc
   source ~/.zshrc  # or source ~/.bashrc
   

Configuration

Environment Variables

The server requires an Unsplash API access key to function. Set it in your environment:

export UNSPLASH_ACCESS_KEY="your-access-key-here"

• Unsplash API Access Key (register at Unsplash Developers Portal)

Obtain an Unsplash API Access Key

1. Go to the Unsplash Developers Portal
2. Sign up or log in to your Unsplash account
3. Register a new application
4. Accept the API use and guidelines
5. Fill in your application details (name, description, etc.)
6. Once registered, you'll receive your Access Key (also called Client ID)

Configure for Claude.app

Add to your Claude settings:

"mcpServers": {
  "unsplash": {
    "command": "unsplash-mcp-server",
    "env": {
      "UNSPLASH_ACCESS_KEY": "your-access-key-here"
    }
  }
}

Configure for Cursor

Add the following configuration to your Cursor editor's settings.json:

{
  "mcpServers": {
    "unsplash": {
      "command": "unsplash-mcp-server",
      "env": {
        "UNSPLASH_ACCESS_KEY": "your-access-key-here"
      }
    }
  }
}

Configure for Chatwise

Note: When adding environment variables in Chatwise, do not wrap the value in quotes (fixes #1)

Command Line Arguments

The server supports the following command line arguments:

• -h, --help: Display help information about the server, its usage, and available options
• -v, --version: Display the version number of the unsplash-mcp-server
• -t, --transport <string>: Transport type to use (default: "stdio")
  • stdio: Standard input/output mode for direct integration with LLMs
  • sse: Server-Sent Events mode for web-based connections
• -p, --port <int>: Port to use when running in SSE mode (default: 8080)

Example usage:

# Display help information
unsplash-mcp-server --help

# Display version information
unsplash-mcp-server --version

# Start server with default settings (stdio mode)
unsplash-mcp-server

# Start server in SSE mode on the default port (8080)
unsplash-mcp-server --transport sse

# Start server in SSE mode on a custom port
unsplash-mcp-server --transport sse --port 9090

When running in SSE mode, the server will be accessible via HTTP on the specified port, allowing web-based clients to connect. In stdio mode (default), the server communicates through standard input/output, which is ideal for direct integration with LLM applications.

Example System Prompt

You can use the following system prompt to help Claude utilize the unsplash-mcp-server effectively:

You have access to Unsplash photo search tools through MCP. You can:

1. Search for photos using specific keywords, colors, or orientations:
   - Use the search_photos tool to find images on any topic
   - Filter by color or orientation as needed
   - You can page through results and control how many appear per page

2. Get detailed information about specific photos:
   - Use get_photo with a photo ID to retrieve comprehensive details
   - This includes EXIF data, location info, and photographer details

3. Fetch random photos with customizable filters:
   - Use random_photo tool to get surprise images based on criteria
   - Filter random selections by topic, collection, username, etc.

When the user asks for images, use these tools to find relevant Unsplash photos.
Include photo URLs in your responses so users can view the images.
