Configure Claude Desktop:

First, make sure you have Claude for Desktop installed. You can install the latest version here. If you already have Claude for Desktop, make sure it's updated to the latest version.

Open your Claude Desktop configuration file:

# MacOS
~/Library/Application Support/Claude/claude_desktop_config.json

# Create the file if it doesn't exist
mkdir -p ~/Library/Application\ Support/Claude
touch ~/Library/Application\ Support/Claude/claude_desktop_config.json

Add the following configuration:

{
  "mcpServers": {
    "email": {
      "command": "/Users/username/.local/bin/uv",
      "args": [
        "--directory",
        "/path/to/claude-post/src/email_client",
        "run",
        "email-client"
      ]
    }
  }
}

Replace /Users/username and /path/to/claude-post with your actual paths.

After updating the configuration, restart Claude Desktop for the changes to take effect.

Running the Server
