# Traktamente MCP Server
An MCP server that provides access to Swedish traktamente (per diem) rates from Skatteverket's official API.
## Features
- 🔍 Query per diem rates by country, year, or country code
- 🌍 Search across all available countries
- 📊 Access official data from Skatteverket
- ⚡ Fast and lightweight implementation using Bun
- 🔒 Type-safe with Zod schema validation
## Installation
```bash
pnpm install traktamente-mcp
```
Or with Bun:
```bash
bun add traktamente-mcp
```
## 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`
```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:
```bash
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):
```json
{
"mcpServers": {
"traktamente": {
"transport": "http",
"url": "https://traktamente.app/mcp"
}
}
}
```
### Standalone Usage
```bash
# 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:
```bash
# 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:
**macOS/Linux**: `~/Library/Application Support/Claude/claude_desktop_config.json`
```json
{
"mcpServers": {
"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.
