Usage

With Claude Desktop

Add this configuration to your Claude Desktop config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "traktamente": {
      "command": "npx",
      "args": ["traktamente-mcp"]
    }
  }
}

Restart Claude Desktop, and you'll have access to three new tools:

get_traktamente - Query per diem rates with filters (country, year, country code)
get_all_countries - List all available countries
search_traktamente - Search for countries using regex patterns

With Streamable HTTP (Remote Server)

The server is available as a hosted service at https://traktamente.app/mcp, which you can connect to without installing anything locally.

Claude Code

The easiest way to add the server to Claude Code is using the CLI:

claude mcp add --transport http traktamente https://traktamente.app/mcp

Alternatively, you can manually add it to your Claude Code settings (~/.config/claude/config.json or via UI settings):

{
  "mcpServers": {
    "traktamente": {
      "transport": "http",
      "url": "https://traktamente.app/mcp"
    }
  }
}

Standalone Usage

# Start the server
bun start

# Development mode with hot reload
bun dev

# Test with MCP Inspector (interactive web UI)
bun run inspector

With Docker

The server can run in a Docker container, useful for isolated environments or deployment:

# Build the Docker image
docker build -t traktamente-mcp .

# Run with stdio transport (interactive)
docker run -i traktamente-mcp

# Or use Docker Compose
docker-compose up

Docker with Claude Desktop

To use the Docker container with Claude Desktop, configure it like this:

    "traktamente": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "traktamente-mcp"]
    }
  }
}

Note: You need to build the Docker image first using docker build -t traktamente-mcp . in the project directory.
