⚠️ Project Status

This project is currently in development and requires additional validation and testing. While the core functionality is implemented, it has not been thoroughly tested in production environments. Please use with caution and report any issues you encounter.

🎯 Overview

The OParl MCP Server provides AI models and applications with seamless access to OParl parliamentary data APIs through the Model Context Protocol. It enables natural language queries and structured access to parliamentary information systems across multiple implementations.

✨ Features

• 🔌 MCP Integration: Full Model Context Protocol compliance
• 🏛️ OParl 1.1 Support: Complete support for all OParl object types
• 🌐 Multi-Implementation: Works with various OParl implementations
• 🔐 Authentication: Flexible API key and Bearer token support
• 📊 Rich Data Access: Parliamentary meetings, documents, organizations, and more
• 🔍 Advanced Search: Query parameters and filtering capabilities
• 🐳 Docker Ready: Containerized deployment with Docker Compose
• 🧪 Comprehensive Testing: Unit tests and integration tests included
• 📚 Extensive Documentation: Complete API reference and usage guides

🏛️ OParl API

The server provides access to all standard OParl 1.1 object types:

Object Type	Description	Key Properties
System	Root system information	oparlVersion, body, created
Body	Parliamentary bodies	name, shortName, organization
Organization	Political parties & groups	name, shortName, member
Person	Representatives & officials	name, givenName, familyName
Meeting	Parliamentary sessions	name, start, end, location
AgendaItem	Meeting topics	name, meeting, order
Paper	Documents & resolutions	name, reference, date
Consultation	Public consultations	name, paper, start, end
File	Attachments & media	name, mimeType, accessUrl
Location	Meeting venues	name, geojson, postalCode

🚀 Quick Start

Prerequisites

• Python 3.11 or higher
• pip (Python package manager)

Installation

1. Clone the repository

   git clone https://github.com/jtwolfe/oparl-mcp-server.git
   cd oparl-mcp-server
   

2. Create a virtual environment

   python -m venv venv
   source venv/bin/activate  # On Windows: venv\Scripts\activate
   

3. Install dependencies

   pip install -r requirements.txt
   

4. Run the server

   python -m oparl_mcp.server
   

Development Setup

For development, install additional dependencies:

pip install -r requirements-dev.txt

⚙️ Configuration

The server can be configured using environment variables or programmatically:

Environment Variables

export OPARL_BASE_URL="https://api.oparl.org"
export OPARL_API_KEY="your-api-key"  # Optional
export OPARL_TIMEOUT="30.0"
export OPARL_LOG_LEVEL="INFO"
export OPARL_SERVER_NAME="OParl MCP Server"

Programmatic Configuration

from oparl_mcp import OParlConfig, OParlMCPServer

# Create configuration
config = OParlConfig(
    base_url="https://oparl.muenchen.de",
    api_key="your-munich-api-key",
    timeout=60.0,
    server_name="Munich OParl Server"
)

# Create and run server
server = OParlMCPServer(config)
server.run()

🌍 OParl Implementations

The server works with various OParl implementations:

Implementation	URL	Description
Generic OParl API	https://api.oparl.org	Standard OParl implementation
Munich City Council	https://oparl.muenchen.de	Munich parliamentary data
Cologne City Council	https://oparl.koeln.de	Cologne parliamentary data
Hamburg Parliament	https://oparl.hamburg.de	Hamburg parliamentary data

Each implementation may have different:

• Authentication requirements
• Available data
• API endpoints
• Rate limits

🐳 Docker

Using Docker Compose

1. Create environment file

   cp .env.example .env
   # Edit .env with your configuration
   

2. Run with Docker Compose

   docker-compose -f docker/docker-compose.yml up -d
   

Using Docker directly

# Build the image
docker build -f docker/Dockerfile -t oparl-mcp-server .

# Run the container
docker run -p 8000:8000 \
  -e OPARL_BASE_URL=https://api.oparl.org \
  -e OPARL_API_KEY=your-key \
  oparl-mcp-server

📖 Usage Examples

Basic MCP Client Usage

from mcp import ClientSession, StdioServerParameters
from mcp.client.stdio import stdio_client

async def main():
    async with stdio_client(StdioServerParameters(
        command="python",
        args=["-m", "oparl_mcp.server"]
    )) as (read, write):
        async with ClientSession(read, write) as session:
            # List all meetings
            meetings = await session.list_resources()
            print(f"Found {len(meetings)} resources")

            # Get specific meeting
            meeting = await session.read_resource("oparl_meeting_123")
            print(f"Meeting: {meeting['name']}")

Advanced Configuration

from oparl_mcp import OParlMCPServer, OParlConfig

# Custom configuration for Munich
config = OParlConfig(
    base_url="https://oparl.muenchen.de",
    api_key="your-munich-api-key",
    timeout=45.0,
    server_name="Munich OParl MCP Server"
)

server = OParlMCPServer(config)
info = server.get_server_info()
print(f"Server: {info['name']}")
print(f"Features: {info['features']}")
