MCP Meetup-Claude Integration Server

Overview

This is a production-quality Model Communication Protocol (MCP) server that seamlessly integrates Meetup.com's event discovery APIs with Anthropic's Claude LLM. The server enables intelligent event discovery, natural language querying, and AI-powered recommendations for Meetup events.

Architecture

Core Components

1. MCP Protocol Handler (MeetupClaudeMCPServer)

   • Manages client connections and tool definitions
   • Handles resource management and server lifecycle
   • Provides standardized MCP interface

2. Authentication Manager (AuthenticationManager)

   • OAuth2 flow implementation for Meetup.com
   • Token lifecycle management and refresh
   • Secure credential handling

3. Event Discovery Engine (EventDiscoveryEngine)

   • Natural language query parameter extraction
   • Dual API support (REST and GraphQL)
   • Intelligent event filtering and ranking

4. Prompt Augmentation Service (PromptAugmentationService)

   • Context-aware prompt enhancement
   • Event data formatting for LLM consumption
   • Smart relevance filtering

5. Claude Integration (ClaudeIntegration)

   • Anthropic API client management
   • Response generation and error handling
   • Configurable model parameters

Data Flow

User Query → Parameter Extraction → Event Discovery → Data Augmentation → Claude Processing → Response

4. Generate new API key
5. Copy the API key securely

3. Environment Configuration

Required environment variables in .env:

MEETUP_CLIENT_ID=your_meetup_client_id_here
MEETUP_CLIENT_SECRET=your_meetup_client_secret_here
ANTHROPIC_API_KEY=your_anthropic_api_key_here

Optional configuration:

MEETUP_ACCESS_TOKEN=your_access_token_if_available
MEETUP_REDIRECT_URI=http://localhost:8080/oauth/callback
LOG_LEVEL=INFO
MAX_EVENTS_PER_QUERY=20
DEFAULT_RADIUS=25

MCP Tools

1. search_meetup_events

Search for Meetup events using natural language queries.

Parameters:

• query (string, required): Natural language search query
• max_results (integer, optional): Maximum events to return (default: 20)

Example:

{
  "query": "Python programming events near San Francisco this week",
  "max_results": 10
}

2. augment_prompt_with_events

Enhance a user prompt with relevant event data for context.

Parameters:

• prompt (string, required): User prompt to augment

Example:

{
  "prompt": "What programming events should I attend this weekend?"
}

3. get_event_recommendations

Get AI-powered event recommendations using Claude with event context.

Parameters:

• query (string, required): Natural language query for recommendations
• preferences (string, optional): Additional preferences or constraints

Example:

{
  "query": "I'm interested in machine learning and networking events",
  "preferences": "Prefer free events, willing to travel up to 30 miles"
}

4. get_oauth_url

Get Meetup OAuth authorization URL for authentication setup.

Parameters: None

MCP Resources

1. meetup://config

Current server configuration and status information.

2. meetup://auth/status

Authentication status with Meetup.com including token validity.

Natural Language Query Examples

The server intelligently extracts parameters from natural language:

Time-based queries:

• "events today"
• "what's happening tomorrow"
• "events this week"

Location-based queries:

• "events near me"
• "meetups in San Francisco"
• "remote events only"

Topic-based queries:

• "Python programming meetups"
• "data science events"
• "startup networking"
• "AI and machine learning"

Combined queries:

• "Python events near me today"
• "remote data science meetups this week"
• "free networking events in San Francisco"

Error Handling

The server includes comprehensive error handling for:

• Authentication errors: Missing credentials, expired tokens
• API errors: Rate limiting, network failures, invalid queries
• Data processing errors: Malformed events, empty results

Security Considerations

• Environment variable configuration prevents credential exposure
• OAuth2 flow implementation follows security best practices
• No persistent storage of user queries or personal data
• Configurable logging levels to control information exposure

Testing

Basic testing can be done by running the server and using MCP client tools:

# Start the server
python meetup_claude_mcp_server.py

# In another terminal, test with MCP client
# (MCP client implementation would go here)

Extending the Server

The modular design makes it easy to extend:

1. Additional APIs: Add other event platforms in EventDiscoveryEngine
2. Enhanced filtering: Extend extract_query_parameters method
3. Caching: Add Redis or memory caching in PromptAugmentationService
4. Additional tools: Add new MCP tools in _setup_tools method

Troubleshooting

Common Issues

1. Authentication failures

   • Verify client ID and secret are correct
   • Check redirect URI matches OAuth consumer settings
   • Ensure access token hasn't expired

2. No events found

   • Try broader search terms
   • Check location spelling and format
   • Verify time parameters are reasonable

3. API rate limiting

   • Reduce query frequency
   • Implement request caching
   • Check API quota usage

4. Claude integration errors

   • Verify Anthropic API key is valid
   • Check API quota and billing status
   • Review prompt length and complexity

Debug Mode

Enable debug logging:

export LOG_LEVEL=DEBUG
python meetup_claude_mcp_server.py

Health Checks

Check server status using MCP resources:

# Check configuration
# Use MCP client to read meetup://config

# Check authentication status
# Use MCP client to read meetup://auth/status
